What is the total displacement of the car after 5 h? Question 4 options: 0 km 15 km 20 km 40km.

Physics
1 answer:
Likurg_2 [28]3 years ago
3 0

Displacement can be defined as the overall change in the position of the object. The displacement of the car in 5 hrs is 0 km.

Displacement:

It is a vector quantity that is defined as the overall change in the position of the object.

The formula for displacement is:

s = s_f-s_i

Where,

s - total displacement

s_f - final position

s_i- initial position

In the given graph:

  • Car displaces 15 km in 2 hrs
  • Car displaces 20 km in 4 hrs.
  • The car moves back to the initial position in 5 hrs.

Therefore, the displacement of the car in 5 hrs is 0 km.

What is the maximum value of the magnetic field at a<br> distance2.5m from a 100-W light bulb?
MA_775_DIABLO [31]

To solve this problem we will apply the concepts related to the intensity included as the power transferred per unit area, where the area is the perpendicular plane in the direction of energy propagation.

Since the propagation occurs in an area of spherical figure we will have to

I = \frac{P}{A}

I = \frac{P}{4\pi r^2}

Replacing with the given power of the Bulb of 100W and the radius of 2.5m we have that

I = \frac{100}{4\pi (2.5)^2}

I = 1.2738W/m^2

The relation between intensity I and E_{max}

I = \frac{E_max^2}{2\mu_0 c}

Here,

\mu_0 = Permeability constant

c = Speed of light

Rearranging for the Maximum Energy and substituting we have then,

E_{max}^2 = 2I\mu_0 c

E_{max}=\sqrt{2I\mu_0 c }

E_{max} = 2(1.2738)(4\pi*10^{-7})(3*10^8)

E_{max} = 30.982 V/m

Finally the maximum magnetic field is given as the change in the Energy per light speed, that is,

B_{max} = \frac{E_{max}}{c}

B_{max} = \frac{30.982 V /m}{3*10^8}

B_{max} = 1.03275 *10{-7} T

Therefore the maximum value of the magnetic field is B_{max} = 1.03275 *10{-7} T
