Answer:
P = 90 W
Explanation:
Mass of an object, m = 30 kg
Speed of the object, v = 15 m/s
Distance, d = 10 m
Work done, W = 900 J
Time, t = 10 s
We need to find the power generated by this project. We know that power is equal to work done divided by time taken.
So,
So, the required power generated is 90 W.
1). Force = (mass) x (acceleration)
Force = (20 kg) x (0.5 m/s )
Force = <em>10 Newtons</em>
2). Force = (mass) x (acceleration)
In this case, the acceleration is the acceleration of gravity.
1 N = (mass) x (9.8 m/s )
Mass = (1 N) / (9.8 m/s )
Mass = <em>0.1 kg</em>
<em></em>
3). Force = (mass) x (acceleration)
This formula is important. Memorize it !
You saw here that the same formula answered both of your questions.
It'll answer a lot more Physics questions that you haven't seen yet.
If you're taking a Physics class, there will DEFINITELY be at least one question on the final exam that will test you to see whether you know this formula and how to use it. Maybe more than one.
Answer:
down below
Explanation:
Image 1- <u>wheels of train</u> showing both translatory motion as well as rotatory motion.
Image 2- <u>rotation of ball</u> shows both rotatory motion as well as translatory motion.
Image 3- <u>the earth rotates</u> about its axis, same time it revolves around the sun thus showing both rotatory motion and curvilinear motion in a fixed time. (perodic motion)
Image 4- while cutting wood, <u>the</u>
<u>carpenter's</u> <u>saw</u> has both
translatory motion and oscillatory
motion, as it moves down while
oscillating.
I think the answer of the Q1 is b, and Q2 the answer is c.
After the waxing gibbous, the lunar phase is the full moon so the answer is A.
