Answer:
yes I think I must have a tree of me I hope it will help you please follow me
W=350 J=M g H
Solve for the height, H
G=9.8 m/s^2
M=7kg
H will be in meters if you use those units.
Answer:
The correct answer to the following question will be "Period".
Explanation:
The Period seems to be the time deemed necessary for such a perfect cycle of vibration to transfer a particular moment. Because as the amplitude of the wave raises, the wavelength falls.
It is denoted by "T" and its formula will be:
⇒ 
Where, T = Period
F = Frequency
The other given choices are not related to the given circumstances. So that the above would be the right answer.
Answer:
The block will not move.
Explanation:
We'll begin by calculating the frictional force. This can be obtained as follow:
Coefficient of friction (µ) = 0.6
Mass of block (m) = 3 Kg
Acceleration due to gravity (g) = 10 m/s²
Normal reaction (R) = mg = 3 × 10 = 30 N
Frictional force (Fբ) =?
Fբ = µR
Fբ = 0.6 × 30
Fբ = 18 N
From the calculations made above, the frictional force of the block is 18 N. Since the frictional force (i.e 18 N) is bigger than the force applied (i.e 14 N), the block will not move.
Answer:
The answer you have selected is correct.
Explanation:
Increase radius, force of gravity decreases
