The Sun delivers an average power of 1150 W/m2 to the top of the Earth’s atmosphere. The permeability of free space is 4π × 10−7
My name is Ann [436]

Answer:

E=930.84 N/C

Explanation:

Given that

I = 1150 W/m²

μ = 4Π x 10⁻⁷

C = 2.999 x 10⁸ m/s

E= C B

C=speed of light

B=Magnetic filed  ,E=Electric filed

Power  P = I A

A=Area=4πr²  ,I=Intensity

I=\dfrac{CB^2}{2\mu_0}

I=\dfrac{CE^2}{2\mu_0 C^2}

E=\sqrt{{2I\mu_0 C}}

E=\sqrt{{2\times 1150\times 4\pi \times 10^{-7}(2.99792\times 10^8)}}

E=930.84 N/C

Therefore answer is 930.84 N/C

A rock is thrown horizontally out of a window with a velocity of 20.0 m/s. If the window is 8.50m above the ground, how far
vladimir1956 [14]

The distance from the base of the building the rock will land is 26.4 m

<h3>Data obtained from the question </h3>
  • Horizontal velocity (u) = 20 m/s
  • Height (h) = 8.50 m
  • Distance (s) =?
<h3>Determination of the time to reach the ground </h3>
  • Height (h) = 8.50 m
  • Acceleration due to gravity (g) = 9.8 m/s²
  • Time (t) =?

h = ½gt²

8.5 = ½ × 9.8 × t²

8.5 = 4.9 × t²

Divide both side by 4.9

t² = 8.5 / 4.9

Take the square root of both side

t = √(8.5 / 4.9)

t = 1.32 s

<h3>How to determine the distance </h3>
  • Horizontal velocity (u) = 20 m/s
  • Time (t) = 1.32 s
  • Distance (s) =?

s = ut

s = 20 × 1.32

s = 26.4 m

A motorcycle is following a car that is traveling at constant speed on a straight highway. Initially, the car and the motorcycle
Sunny_sXe [5.5K]

Answer:

a) 5.09 seconds

b) 107.07 meters

Explanation:

a) As we know

t_2- t_1 = \sqrt{\frac{2 X}{a} }

Substituting the given values we get

t_2 - t_1 = \sqrt{\frac{2 * 52}{4} } \\t_2 - t_1 = 5.09

It takes 5 .09 s for the motorcycle to accelerate until it catches up with the car

b)

X_{t`2} = v_i \sqrt{\frac{2X}{a} } + 0.5 a\sqrt{\frac{2X}{a} }\\X_{t`2} =  (v_i + 0.5 a) \sqrt{\frac{2X}{a} }\\X_{t`2} =  ( 19 + 2)  \sqrt{\frac{2* 52}{4} }\\X_{t`2} =  21 * 5.09\\X_{t`2} = 107.07
