Answer:

C. light in which the electric and magnetic vectors oscillate perpendicular to the direction of propagation of the wave

Explanation:

Light is an electromagnetic wave in which electric field vector and magnetic field vector both oscillates perpendicular to each other and also these two components are perpendicular to the propagation of wave.

As we know that the direction of velocity of wave is given by the formula

\vec E \times \vec B = \vec v

so here the velocity vector must be perpendicular to vector E and vector B

so here correct answer will be

C. light in which the electric and magnetic vectors oscillate perpendicular to the direction of propagation of the wave

A driver averaged 64 mph and took 3½ hours to travel from st. Louis to chicago. Based on this, what is the distance between st.
sammy [17]

Average speed of the driver is given as

v = 64 mph

if he moved for total time t = 3.5 hours

so the distance between the tow is given as

d = v* t

d = 64 * 3.5

d = 224 miles

so the distance between St. Louis and Chicago is 224 miles

A 3.9 kg ball traveling towards a soccer player at a velocity of -3.5 m/s rebounds off the soccer player's foot at a velocity of
Tresset [83]

Answer: 2.92 s

Explanation:

Given

Mass of ball is m=3.9\ kg

The initial velocity of the ball is u=-3.5\ m/s

Velocity after the rebound is v=15.9\ m/s

Force during the contact is F=25.9\ N

We know, change in momentum is Impulse

\Rightarrow F\cdot \Delta t=m(\Delta v)

\Rightarrow 25.9\cdot \Delta t=3.9(15.9-(-3.5))\\\\\Rightarrow \Delta t=\dfrac{3.9\times 19.4}{25.9}=2.92\ s

Thus, the force is applied for 2.92 s
