What happens to a day of light that slows down when it hits a new medium at an angle

Anika [276]

Light travels as transverse waves and faster than sound. It can be reflected, refracted and dispersed. Ray diagrams show what happens to light in mirrors and lenses. Eyes and cameras detect light.

A brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 780 N on him. The

stich3 [128]

Answer:

$f = 556.4 N$

Explanation:

Mass of the losing player with its all equipment is given as

M = 86 kg

Net force applied on him by another player is given as

F = 780 N

also we know that acceleration of the losing player is given as

$a = 2.6 m/s^2$

now by Newton's 2nd law we will have

$F - f = ma$

$780 - f = 86(2.6)$

$780 - f = 223.6$

$f = 556.4 N$

5. average A body sets off from rest with a constant acceleration of 8.0 m/s? What distance will it have covered after 3.0 s? 6.

chubhunter [2.5K]

Answer:

$\boxed {\boxed {\sf 36 \ meters}}$

Explanation:

We are asked to find the distance a body covers. We know the initial velocity, acceleration, and time, so we will use the following kinematic equation.

$d= v_i t+ \frac {1}{2} \ at^2$
