Well, all the words are common, but I try to answer in my way. The way how light is used to study space is finding distance between the planets, which is called a light year. According to the <span>scientist's beliefs the space is but a vaccum and the only body that can travel through it is light, that's why light is very importand for discovering space.
</span>Hope you will find it helpful!
Answer:
So the minimum force is
32.2Newton
Explanation:
To solve for the minimum force, let us assume it to be F (N)
So
F=mgsinA
But
=>>>> coefficient of static friction x (F + mgcosA
=>3 x 9.8 x sin35 = 0.3 x (F + 3 x 9.8 x cos35)
So making F subject of formula
F + 24.0 = 56.2
F = 32.2N
Answer:
250

because some people control some parts of the space shuttle launcher and some people control other parts of it
Answer:
Explanation:
<u>Given Data:</u>
Cycles = c = 3 cycles
Time = t = 2 seconds
<u>Required:</u>
Time period = T = ?
<u>Formula:</u>
1) f = c/t
2) T = 1/f
<u>Solution:</u>
<u>Finding frequency first:</u>
f = c / t
f = 3/2
f = 1.5 Hz
<u>Now, finding period:</u>
T = 1/f
T = 1 / 1.5
T = 0.67 seconds
