You were approximately 5.72 meters away from the second baseman. The vertical drop or distance between point A and point B was approximately 0.4576 meters.

To determine the distance between you (the shortstop) and the second baseman, we can use the formula for horizontal distance (d) traveled by an object moving at a constant horizontal velocity:

d = v * t

where:

- d is the horizontal distance traveled,

- v is the horizontal velocity of the ball,

- t is the time taken.

Given that the horizontal velocity (v) is 13 m/s and the time (t) is 0.44 s, we can calculate the horizontal distance (d) as follows:

d = 13 m/s * 0.44 s = 5.72 meters

So, you were approximately 5.72 meters away from the second baseman.

To find the vertical drop or the distance between point A and point B, we need to calculate the vertical component of the ball's motion. Since the ball is thrown horizontally, it will experience a constant vertical acceleration due to gravity.

The formula to calculate the distance (d) traveled vertically in free fall is:

d = 1/2 * g * t²

where:

- d is the vertical distance traveled,

- g is the acceleration due to gravity (approximately 9.8 m/s²),

- t is the time taken.

Given that the time (t) is 0.44 s, we can calculate the vertical distance (d) as follows:

d = 1/2 * 9.8 m/s² * (0.44 s)² = 0.4576 meters

So, the vertical drop or the distance between point A and point B is approximately 0.4576 meters.

Part (a) To find the total capacitance of the circuit, we need to use the formula for capacitors in parallel and series. In this case, the accelerationare in both parallel and series, so we need to break it down into steps.

First, we can find the equivalent capacitance of C1 and C2 in parallel: C12 = (C1 x C2) / (C1 + C2) = (7.8 ?F x 13.2 ?F) / (7.8 ?F + 13.2 ?F) = 4.96 ?F.

Then, we can find the total capacitance of C12 and C3 in series: C123 = 1 / ((1 / C12) + (1 / C3)) = 1 / ((1 / 4.96 ?F) + (1 / 4.9 ?F)) = 2.45 ?F.

Therefore, the total capacitance of the circuit is 2.45 ?F.

Part (b) To find the total energy stored in the capacitors, we can use the formula U = 0.5 x C x V^2, where U is the energy stored, C is the capacitance, and V is the voltage.

For C1, U1 = 0.5 x 7.8 ?F x (12 V)^2 = 673.92 ?J.
For C2, U2 = 0.5 x 13.2 ?F x (12 V)^2 = 1,411.2 ?J.
For C3, U3 = 0.5 x 4.9 ?F x (12 V)^2 = 352.8 ?J.

The total energy stored in the capacitors is U = U1 + U2 + U3 = 2,437.92 ?J.

Therefore, the numerical value of the total capacitance of the circuit is 2.45 ?F and the numerical value of the total energy stored in the capacitors is 2,437.92 ?J.

According to Newton's third law of motion the force exerted by the car on the wall and the force by the wall on the car are equal and opposite. But there will be no displacement for the wall.

Collison is a short time force acting between two objects. There are both elastic and inelastic collision. In elastic collision, the kinetic energy and momentum of the colliding system is conserved whereas in inelastic collision, the kinetic energy is not conserved.

For any type of collision, we can apply Newton's third law of motion. This law states that, for every action there is an equal and opposite reaction. Therefore, in a collision, the force exerted by each object will be equal and opposite in direction.

Answer:

KE=800,000

Explanation:

The formula for kinetic energy is KE=1/2mv^2 or Kinetic Energy= 0.5*mass*velocity^2

so 1000 is the mass and 40 is the velocity

KE=0.5*1000*40^2

KE=0.5*1,000*1,600

KE=800,000 Joules

We will see that the electric field in that point is:

Ex = 31.598 N/μc

Remember that for a charge Q, the electric field is given by:

\(E = k*\frac{Q}{r^2} (n_x, n_y)\)

Where the versor is in the direction of r,  k is a constant, and r is the distance to the charge.

In this case, we have two charges, one at  (0cm, 5cm) and the other at (0cm, -5cm). Because of the symmetry on the y-axis, we know that the y-component will be canceled, so we only have the x-component.

\(E_x = k*(\frac{30 \mu C}{(12cm)^2 + (5cm)^2} + \frac{30 \mu C}{(12cm)^2 + (-5cm)^2} )\\\\E_x = k*(\frac{60 \mu C}{169cm^2})\)

Now we know that the value of k, the Coulomb's constant is:

k = 8,9*10^9 N*m^2/C^2

Writing this in cm and μc (multiplying by 10^4 and dividing by 10^12 we get)

k = 8.9*10^9*(10^4*10^-12) N*cm^2/μc^2

k =  8.9*10 N*cm^2/μc^2

Now we use that in our equation:

\(E_x = (8.9*10 N*cm^2/\mu c^2)*(\frac{60 \mu C}{169cm^2}) = 31.598N/\mu c\)

This is the electric field on the point (12cm, 0cm).

Explanation:

a. Part A: The area of each plate is required for for a 0.300 uF capacitor is 1.56 × \(10^{-4}\) m².

b. Part B: If the electric field in the paper is not to exceed one-half the dielectric strength, the maximum potential difference that can be applied across the compactor is 2025 V.

To find the area of each plate required for a 0.300 uF capacitor, use the formula:

C = ε₀εrA/d

where C is the capacitance, ε₀ is the vacuum permittivity (8.85 × \(10^{-12}\) F/m), εr is the relative permittivity (dielectric constant), A is the area, and d is the distance between the plates. In this case,

C = 0.300 uF

εr = 2.10

d = 8.10 × \(10^{-5}\) m.

Rearrange the formula to find A:

A = Cd / (ε₀εr)

A = (0.300 × \(10^{-6}\) F)(8.10 × \(10^{-5}\) m) / (8.85 × \(10^{-12}\) F/m × 2.10)

A ≈ 1.56 × \(10^{-4}\) m²

Thus, the area of each plate required for a 0.300 uF capacitor is approximately 1.56 × \(10^{-4}\) m².

To find the maximum potential difference that can be applied across the capacitor, use the formula:

V = Ed

where E is the electric field and d is the distance between the plates. In this case, E is half the dielectric strength (50.0 MV/m / 2 = 25.0 MV/m), and d = 8.10 × \(10^{-5}\) m:

V = (25.0 × 10^6 V/m)(8.10 × 10^-5 m)

V ≈ 2025 V

Thus, the maximum potential difference that can be applied across the capacitor without exceeding one-half the dielectric strength is approximately 2025 V.

Answer:

The rider experiences weight or does not experience weight depends upon the direction of the elevator in which it moves and its acceleration.  

Explanation:

Consider the mass of a rider as m. So its actual weight is mg and it acts vertically downward. The apparent weight of the rider is depended on the acceleration of the elevator and its direction of movement.

When elevator moves with a constant speed i.e. its acceleration is zero, the apparent weight of the rider is equal to the actual weight. Thus the rider's sensation is normal.

If the elevator is moving upward with an acceleration a, then the apparent weight of the rider will be more and the rider will experience an increase in weight or the sensation is heavy.

Or when the elevator moves downward with an acceleration a, the apparent weight of the rider is less. And the rider sensation is lighter.

The acceleration will become "0 (zero)". A further solution to the question is provided below.

Now,

→ \(mg= W+F\)

or,

→ \(g= a+g\)

then,

→ \(a =0\)

This means that the rider isn't moving. Thus the response above is appropriate.

The moment of inertia of a 5.00 kg sphere of radius 0.741 m when the axis of rotation is through its center is 0.777 kg·m².

The moment of inertia of an object is a measure of its resistance to rotational motion around a given axis. For a solid sphere rotating around an axis through its center, the moment of inertia can be calculated using the formula I = (2/5) * m * r², where I is the moment of inertia, m is the mass of the sphere, and r is the radius of the sphere.

Applying the given values, we have I = (2/5) * 5.00 kg * (0.741 m)². Simplifying the equation yields I = 0.777 kg·m².

This means that when the sphere rotates around an axis passing through its center, it has a moment of inertia of 0.777 kg·m². The moment of inertia quantifies how the mass is distributed around the axis of rotation, and a larger moment of inertia indicates greater resistance to changes in rotational motion.

Force of air and gravitational force are acting on the ball when launched from the slingshot.

When a ball is launched from a slingshot, during its travel force of air as well as gravitational force are acting on the ball because there is air which moves opposite to the motion of a ball whereas the force of gravity attracts the ball downward.

The force of air slows down the motion of the ball while on the other hand, the force of gravity brings the ball to the ground due to attraction. If these two forces are not present then the ball continues its motion forever so we can conclude that force of air and force of gravity are acting on the ball when launched from the slingshot.

Explanation:

It was Newton's genius that saw that it was true. He also realized that if it was true, the motion the earth experience would be unmeasurably small, especially in his time. Their instruments were just not good enough: crude and too approximate would be better descriptions.

The velocity of the canister relative to the Earth when shot directly away from the Earth is approximately 0.9091c.

We'll be using the terms "spaceship," "velocity," "canister," "relative to the ship," and "relative to the Earth" in our answer. We'll also be using the relativistic velocity addition formula: (u + v) / (1 + uv/c^2).

(a) If the canister is shot directly at the Earth, we have:
u = 0.750c (velocity of spaceship relative to Earth)
v = -0.500c (velocity of canister relative to spaceship, negative sign because it's shot towards Earth)
c = speed of light

Using the relativistic velocity addition formula:
(0.750c - 0.500c) / (1 - 0.750 * -0.500) = (0.250c) / (1 + 0.375) = 0.250c / 1.375 ≈ 0.1818c

So, the velocity of the canister relative to the Earth when shot directly at the Earth is approximately 0.1818c.

(b) If the canister is shot directly away from the Earth, we have:
u = 0.750c (velocity of spaceship relative to Earth)
v = 0.500c (velocity of canister relative to spaceship)

Using the relativistic velocity addition formula:
(0.750c + 0.500c) / (1 + 0.750 * 0.500) = (1.250c) / (1 + 0.375) = 1.250c / 1.375 ≈ 0.9091c

Answer:

The formula for calculating the length change due to a temperature change is:

ΔL = α * L * ΔT

where α is the linear expansivity, L is the original length of the bar, and ΔT is the change in temperature.

So in this case, the length change of each bar would be:

ΔL = 1.0 x 10^-5 K^-1 * 3m * (40°C - 28°C)

Converting the temperatures to Kelvin (28°C = 28 + 273 = 301 K and 40°C = 40 + 273 = 313 K), we get:

ΔL = 1.0 x 10^-5 K^-1 * 3m * (313 K - 301 K)

ΔL = 1.0 x 10^-5 * 3 * 12

ΔL = 0.00036 m

So each bar will increase in length by approximately 0.00036 meters when the temperature changes from 28°C to 40°C. To allow for this increase in length, a safety gap of 0.00036 meters should be left between each bar.

A. The percentage change in volume of the copper cube is 3%.

B. The force necessary to stretch a 2.0 mm diameter steel wire by 1% is approximately 25.1 N.

A.

To find the percentage change in volume of the copper cube, we can use the formula:

ΔV/V = 3BΔP/Β

Where ΔV/V is the fractional change in volume,

B is the bulk modulus of the material (given as \(14\times10^{10}\: N/m^2\) for copper), and ΔP is the change in pressure.

Since the pressure is the same on all six sides of the cube,

ΔP = \(7.0\times10^5 \:N/m^2.\)

Substituting the values into the formula, we get:

ΔV/V = \(3(14\times10^{10}\: N/m^2)(7.0\times10^5 N/m^2)/(14\times10^{10}\: N/m^2)\)

ΔV/V = 0.03 or 3%

B.

To find the force necessary to stretch a 2.0 mm diameter steel wire by 1%, we can use the formula:

F = AΔL Y/L

Where F is the force required,

A is the cross-sectional area of the wire (given as πr^2, where r = 1.0 mm = 0.001 m),

ΔL is the change in length (given as 1% of the original length, or 0.01 x 2.0 mm = 0.02 mm = 0.00002 m),

Y is the Young's modulus of the material (given as 2.0x10^11 N/m^2), and L is the original length of the wire (which we will assume to be 1 meter for simplicity).

Substituting the values into the formula, we get:

F = \(\pi(0.001 m)^2 (0.00002 \:m) (2.0\times10^{11}\: N/m^2) / 1 m\)

F ≈ 25.1 N
