what is the difference between speed and velocity? what is the difference between speed and velocity? velocity contains information about the direction of motion while speed does not. speed is an average quantity while velocity is not. the concept of speed applies only to objects that are neither speeding up nor slowing down, while velocity applies to every kind of motion. speed is measured in mph, while velocity is measured in m/s.

Answer:

4m/s^2

Explanation:

using the formula a = (v_f - v_i) / Δt we can use final velocity, initial velocity, and accel. time to calculate the accel. rate

In this problem it would be a=(26m/s - 10m/s) / 4s

our answer would be 4m/s^2

The magnetic field forms a 51.8 ⁰C angle with an axis perpendicular to the plane of the triangle.

The total territory enclosed by the three sides of any particular triangle is defined as its area. In general, it is equal to half of the base times the height, i.e. A = 1/2 b h. The sum of a triangle's three interior angles equals 180 degrees. If ABC is a triangle, then A + B + C = 180°, according to this theorem. Theorem 2: An isosceles triangle's base angles are equivalent.

A triangle's total area is equal to half of its base multiplied by its height. The altitude is calculated using the Pythagorean equation.

h=√(8cm)-(4cm)=4/3cm

As a result, the area of a triangle,

A=0.5bh-(0.08m)(4/3x10m)-2.77x 10m

Then, align equation (2) for e to get

Explanation:

The correct answer is option C.

Two electromagnetic waves are traveling through a material. Wave 1 has a maximum electric field strength that is three times the maximum field strength of wave 2. The average intensity of Wave 1 is nine times the intensity of Wave 2.

By comparing the two electromagnetic waves, we get:

Maximum Electric Field Strength of Wave(1) = 3 x Maximum Electric Field Strength of Wave (2), i.e.

\(E_{1}\)  = 3 x \(E_{2}\)

Now comparing the average intensities of the two waves. we get \(\frac{I1}{I2}\)

The average intensity of electromagnetic wave 1 can be expressed as:

\(I_{1}\) = \(\frac{1}{2}\) x ε0 x  \(E1^{2}\) x c ------- (1)

Now, the average intensity of the electro-magnetic wave 2 can be expressed as:

\(I_{2}\)  =  \(\frac{1}{2}\) x ε0 x  \(E2^{2}\)  x c -----(2)

Now comparing equations 1 and 2 we get.

\(\frac{I1}{I2}\)  =   \(E1^{2}\) /  \(E2^{2}\)

\(\frac{I1}{I2}\)  =  ( 3 x \(E2)^{2}\)/  \(E2^{2}\)

\(\frac{I1}{I2}\)  = 9

Thus, we can say that the average intensity of Wave 1 is nine times the intensity of Wave 2.

The weight of a \(45 kg\) box is \(441.45 N\).

Weight refers to the measure of the force exerted on an object due to the gravitational pull of the Earth.

Given the mass of the box is \(m=45 kg\).

The weight of an object (\(W\)) can be found by multiplying the mass of the object (\(m\)) by the acceleration due to gravity (\(g\)).

So, \(W=mg\).

It is known that acceleration due to gravity, \(g=9.81 m/s^2\).

Hence, the weight of the box, \(W=(45kg)\times (9.81 m/s^2)\).

\(\Rightarrow W=441.45 (kg\cdot m/s^2)\\\Rightarrow W=441.45 N\)

Therefore, the weight of the box is \(441.45 N\).

Given the velocity versus time graph of an object.

From the graph, the velocity of object A is constant as the line representing its velocity is horizontal. The velocity of object a is decreasing with time. That is, object B is decelerating.

From the graph, at t=5 s the value of the instantaneous velocity of object A is 0 m/s.

And the value of the instantaneous velocity of object B is the same throughout the graph. And the value is 4 m/s.

Thus the value of the instantaneous velocity of object B is greater than that of object A.

Thus the correct answer is B has the greater value

The magnitude of the force of gravity that is acting on the objects is  1.33 × 10^−10 N.

We know that the gravitational force is an attractive force that acts on all the objects that do exist in the universe. Thus, once  body lies within the gravitational field of the earth this force of gravity can be said to act on the object. We have in the question two objects that are positioned on the cartesian coordinates as shown. The distance between the objects is 2 m.

Using the formula;

F = Gm1m2/r^2

F = gravitational force

G = gravitational constant

m1  and m2 = masses of the objects

r = distance of separation

Then we have;

F = 6.6726 × 10^−11 * 4 * 2/(2)^2

F = 1.33 × 10^−10 N

Thus the attractive force has a magnitude of  1.33 × 10^−10 N.

The energies of the first four rotational levels of 1H127I can be calculated using the formula:

E = B(J(J+1))

where B is the rotational constant, J is the rotational quantum number, and h and c are Planck's constant and the speed of light, respectively.

The rotational constant can be calculated using the moment of inertia formula I=μR^2 as follows:

B = h/(8π^2cI)

where h is Planck's constant, c is the speed of light, and I is the moment of inertia.

Substituting the given values we get:

μ = mHmI/(mH+mI) = (1.0078 amu * 126.9045 amu)/(1.0078 amu + 126.9045 amu) = 1.002 amu

I = μR^2 = (1.002 amu)(160 pm)^2 = 0.004921 kg m^2

B = h/(8π^2cI) = (6.626 x 10^-34 Js)/(8π^2 x 3 x 10^8 m/s x 0.004921 kg m^2) = 2.921 x 10^-23 J

Using the formula above, the energies of the first four rotational levels are:

E1 = B(1(1+1)) = 2B = 5.842 x 10^-23 J

E2 = B(2(2+1)) = 6B = 1.7526 x 10^-22 J

E3 = B(3(3+1)) = 12B = 3.5051 x 10^-22 J

E4 = B(4(4+1)) = 20B = 5.842 x 10^-22 J

Part A: The average power output of the human sprinter is approximately 1002.3 watts.

Part B: The average power output of the greyhound is approximately 2746.3 watts.

Part A: To calculate the average power output of the human sprinter, we can use the formula ΔE/Δt, where ΔE is the change in energy and Δt is the time interval. The change in energy can be calculated using the formula ΔE = (1/2)mv², where m is the mass and v is the final velocity.

ΔE = (1/2) * 73 kg * (10 m/s)² = 3650 J

The time interval is given as 3.5 seconds, so we can now calculate the average power:

Average power = ΔE/Δt = 3650 J / 3.5 s ≈ 1002.3 W

Therefore, the average power output of the human sprinter is approximately 1002.3 watts.

Part B: Similarly, for the greyhound, we can calculate the change in energy using the same formula:

ΔE = (1/2) * 29 kg * (20 m/s)² = 11600 J

Using the same time interval of 3.5 seconds, we can calculate the average power:

Average power = ΔE/Δt = 11600 J / 3.5 s ≈ 2746.3 W

Therefore, the average power output of the greyhound is approximately 2746.3 watts.

What is the magnitude of the boat’s resultant velocity? Round your answer to the nearest whole number.

answer :  25.73 m/s

Explanation:

Given

V1 = 15 miles/hour =  6.71 m/s [ 45° EN ]

V2 = 18 m/s [ 5° NE ]

Calculate  the resultant velocity

Vr = 6.71 m/s[45°] + 18m/s[5°].

Vr = ( 6.71 *Cos45° + 6.71 *sin45°) + ( 18 *Cos5° + 18*sin5° )

Vr = ( 4.74  + 4.74 i  )+  ( 17.93 + 1.57i) = 22.67 + 12.18i.

Therefore the magnitude

the position relative to the center where the electric field is a maximum is at the center itself, where x = 0. At this point, the electric field magnitude is:

E = (kq/d^2) * 2sinθ

The electric field vector at a point along the perpendicular bisector of two equal positive charges is given by:

E = (kq/r^2) * (sinθ1 + sinθ2)

where k is Coulomb's constant, q is the charge, r is the distance from the charges to the point of interest, θ1 and θ2 are the angles between the line connecting the charges and the perpendicular bisector, and θ1 = θ2.

In this case, θ1 = θ2 = θ, and the distance from each charge to the point of interest is d/2. Therefore, we have:

r = sqrt((d/2)^2 + x^2)

where x is the distance from the center alongbthe perpendicular bisector.

Substituting this into the equation for the electric field, we get:

E = (kq/(d^2/4 + x^2)) * 2sinθ

where we used the identity sinθ1 + sinθ2 = 2sinθ.

Tofind the position relative to the center where the electric field is a maximum, we differentiate E with respect to x and set it equal to zero

dE/dx = -2kq/(d^2/4 + x^2)^2 * 2xsinθ = 0
