The refraction occurs because when the light beam hits the prism, it is bent and light ricochets and the light is sometimes separated into the different colors.

Spacecraft have been sent to Mars in recent years. Mars is smaller than Earth and has correspondingly weaker surface gravity. On Mars, the free-fall acceleration is only 3.8m/s2. What is the orbital period of a spacecraft in a low orbit near the surface of Mars?
Answer:
Explanation:
Given
To find
orbital period of a spacecraft T
Solution
An the initial calculating is computing the angular velocity of satellite :
Computing T
Answer:
Explanation:
Height attained by body = 50 cm
= .5 m
Initial velocity = u
v² = u² - 2gh
0 = u² - 2gh
u² = 2 x 9.8 x .5
u = 3.13 m /s
During the initial period , the muscle stretches by around 10 cm during which force by ground reacts on the body and gives acceleration to achieve velocity of 3.13 m/s from zero .
v² = u² + 2as
3.13² = 0 + 2 a x .10
a = 49 m/s²
reaction by ground R
Net force
R-mg = ma
R= m ( g +a )
= mg + ma
=W + (W/g) x a
W ( 1 + a / g )
= W ( 1 + 49 / 9.8 )
= 6W
F = M (V^2/r) = 20 x 100 /.15 =13333.33 N<span>convert units as needed to wind up with Newtons Kg-m/s^2 hope it helps :)</span>
Answer:Spot B
Explanation:
Mary will Reject spot B which can be explained by the process of Selective thinking.
Selective reasoning is the practice in which one chooses favorable memory and concentration information while ignoring unfavorable proof of belief.
This kind of reasoning is the foundation of most beliefs in so-called mind readers and media's psychic powers. It is also the basis of many, though not all, mysticism and pseudo science beliefs.
though hotels are modern but the presence of very cold water and strong winds might become the factors to reject spot B
