Probably late but the change in motion of the man is in his speed, I know because every 0.2 seconds, he was gaining more distance as he was the previous 0.2 seconds. His acceleration positive because he was speeding up.

Explanation:

Hope it Helps!

( I realized he started off speeding up but then started slowning down so I am confused if you get this wrong Im so sorry.)

Acceleration is defined as the rate of change of the velocity of the body. The acceleration of the man is positive due to its increased velocity.

Acceleration is defined as the rate of change of the velocity of the body. Its unit is m/sec².It is a vector quantity. It requires both magnitudes as well as direction to define.

The acceleration of the man is positive because acceleration is the rate of change of velocity and the velocity of the person is increasing at an equal interval of time showing that the acceleration is increasing and positive in nature.

Hence due to successive velocity, the acceleration of the man is positive.

How this amendment would benefit is that it would be more structured in Congress.

A ball is dropped from a height of 10 m. Its velocity upon impact with the ground is (v) = (a) 14 m/s.

Velocity is a term that means that the object has changed its position by making a distance in a given time. That called the velocity of the object. It can be measured in m/s, cm/s.

To calculate the velocity we are using the formula,

v²-u²=2gh

As we know the ball start velocity from rest so, u=0

v²=2gh

Or, v=√2gh

Here we are given,

h= the height of the cliff from the ball fell. = 10m.

g= The acceleration due to gravity. = 9.8 m/s².

We have to calculate the velocity of the ball = v m/s.

Now we put the values in above equation, we get

v=√2gh

Or, v= √2*9.8*10

Or, v= 14 m/s.

So from this we can say that, Its velocity upon impact with the ground is (v) = (a) 14 m/s

Hope this helps, good luck.

The speed of object A at the end of the ramp is approximately 25.39 m/s.

Part (a) The two objects, A (solid cylinder) and B (hollow cylinder), will reach the bottom of the ramp at the same time.

The time it takes for an object to reach the bottom of a ramp depends on its mass distribution and shape, not on whether it is solid or hollow.

In the absence of any other information, we can assume that both objects have similar mass distributions and roll without slipping, resulting in them reaching the bottom of the ramp simultaneously.

Therefore, the answer is 3) They will reach the bottom at the same time.

Part (b) To calculate the speed of object A at the end of the ramp, we can use the principle of conservation of energy.

The potential energy at the beginning of the ramp is converted into kinetic energy at the bottom of the ramp.

The potential energy (PE) at the beginning of the ramp is given by:

PE = m * g * h

where m is the mass of object A, g is the acceleration due to gravity, and h is the height of the beginning of the ramp.

Mass of object A (m) = 340 g = 0.34 kg

Radius of object A (r) = 31 cm = 0.31 m

Height of the beginning of the ramp (h) = 41 cm = 0.41 m

Acceleration due to gravity (g) = 9.8 m/s²

The potential energy at the beginning of the ramp is:

PE = 0.34 kg * 9.8 m/s² * 0.41 m

PE ≈ 1.375 J

At the bottom of the ramp, the potential energy is fully converted into kinetic energy:

KE = 1/2 * I * ω²

where I is the moment of inertia of the object and ω is the angular velocity.

For a solid cylinder, the moment of inertia is given by:

I = (1/2) * m * r²

Substituting the given values:

I = (1/2) * 0.34 kg * (0.31 m)²

I ≈ 0.0169 kg·m²

Since the object rolls without slipping, the linear speed (v) can be related to the angular velocity (ω) by the equation:

v = ω * r

Solving for ω:

ω = v / r

The linear speed at the end of the ramp is equal to the radius times the angular velocity.

Substituting the values:

v = (1.375 J / 0.0169 kg·m²) * 0.31 m

v ≈ 25.39 m/s

Part A: The spring stiffness constant is approximately 63.6 N/m.

Part B: The amplitude of vibration is approximately 0.017 m.

Part C: The frequency of vibration is approximately 2.73 Hz.

To determine the spring stiffness constant, we can use Hooke's Law, which states that the force exerted by a spring is directly proportional to the displacement of the spring from its equilibrium position.

Part A:

Given:

Stretch of the scale (displacement), Δx = 3.3 cm = 0.033 m

Weight of the fish, F = 2.1 kg

Hooke's Law equation:

F = k * Δx

Rearranging the equation to solve for the spring stiffness constant:

k = F / Δx

Substituting the given values:

k = 2.1 kg / 0.033 m ≈ 63.6 N/m

Therefore, the spring stiffness constant is approximately 63.6 N/m.

Part B:

To find the amplitude of vibration, we need to determine the maximum displacement from the equilibrium position. In simple harmonic motion, the amplitude is equal to half the total displacement.

Given:

Total displacement, Δx = 3.4 cm = 0.034 m

Amplitude, A = Δx / 2

Substituting the given value:

A = 0.034 m / 2 = 0.017 m

Therefore, the amplitude of vibration is approximately 0.017 m.

Part C:

The frequency of vibration can be calculated using the formula:

f = (1 / 2π) * √(k / m)

Given:

Spring stiffness constant, k = 63.6 N/m

Mass of the fish, m = 2.1 kg

Substituting the given values into the formula:

f = (1 / 2π) * √(63.6 N/m / 2.1 kg)

Calculating the frequency:

f ≈ (1 / 2π) * √(30.2857 N/kg) ≈ 2.73 Hz

Therefore, the frequency of vibration is approximately 2.73 Hz.

The formula for the impulse exerted on the ball from the instant it is dropped to an arbitrary time later is:

Impulse = (Final momentum - Initial momentum)

Impulse is a vector quantity having both magnitude and direction, whereas momentum is a vector quantity, but the impulse is not equal to momentum. The impulse is the change in momentum.

If a ball of mass m is dropped from rest, then its initial momentum is zero.

The final momentum of the ball after falling for time t is:

Final momentum = mv

Where v is the velocity of the ball after falling for time t.

Therefore, the impulse exerted on the ball from the instant it is dropped to an arbitrary time later is:

Impulse = (mv - 0) = mv

The other car is traveling at approximately 68.8 mph.

To find the speed of the other car, we can use the fact that the distance between the two cars is increasing at a rate of 20 mph. This means that the rate at which the distance between them is changing is equal to the difference in their speeds. Let's call the speed of the other car "x".

Using the Pythagorean theorem, we can find the initial distance between the two cars:

sqrt((0.6)^2 + (0.8)^2) = 1 mile

Now we can set up an equation:

x - 60 = 20

This is because the police car is traveling at a constant speed of 60 mph, and the distance between the two cars is increasing at a rate of 20 mph.

Solving for x, we get:

x = 80

However, this is the speed of the other car relative to the police car. To find the actual speed of the other car, we need to add the speed of the police car:

x + 60 = 68.8 mph (rounded to one decimal place)

Therefore, the other car is traveling at approximately 68.8 mph.

(a) The total number of bright fringes is 172, including the central fringe and those on both sides. (b) The fringe that is most distant from the central bright fringe will occur at an angle of approximately 3.00 degrees.

When a laser beam of wavelength 585 nm is passed through two parallel slits that are 0.0116 mm apart, bright fringes are observed on a distant screen due to constructive interference of the light waves. The total number of bright fringes including the central fringe and those on both sides can be determined by considering the maximum value of the sine function. This leads to the formula N = (d sinθ)/λ, where d is the distance between the slits, λ is the wavelength of light, θ is the angle of diffraction, and N is the number of bright fringes. Using this formula, the total number of bright fringes is calculated to be 172. The fringe that is most distant from the central bright fringe occurs at an angle of approximately 3.00 degrees.

To find the current in the resistor, we can use Ohm's Law and the concept of equivalent resistance. Thus, option A is correct.

First, let's calculate the equivalent resistance of the three cells connected in parallel. When resistors are connected in parallel, the reciprocal of the equivalent resistance is equal to the sum of the reciprocals of the individual resistances:

1/Req = 1/R1 + 1/R2 + 1/R3

Given that R1 = R2 = R3 = 22 Ω (internal resistance of each cell), we can substitute the values:

1/Req = 1/22 + 1/22 + 1/22

1/Req = 3/22

Taking the reciprocal of both sides, we find:

Req = 22/3 Ω

Now we can use Ohm's Law to calculate the current (I) in the resistor. Ohm's Law states that the current flowing through a resistor is equal to the voltage across it divided by its resistance:

I = V/R

Given that V = 1.1 V (emf of each cell) and R = 32 Ω (resistance), we can substitute the values:

I = 1.1/32

Calculating this value, we find:

I ≈ 0.034375 A

Therefore, the current in the resistor is approximately 0.034375 A.

The reflective surface of a concave mirror is curved inward and away from the light source. Concave mirrors focus light inward to a single focal point. In contrast to convex mirrors, the image formed by a concave mirror changes depending on the distance between the object and the mirror.

Given ,

In concave lens

focal length f =+25

object distance  u =20cm
