It grows every time it needs to grow for the population of the environment
Answer:
Newtons law of conservation energy says that energy cannot be created or destroyed because energy is always made into something else. It is always reused.
Explanation:
Answer:
19.6 kg*m/s^2 = 19.6 N
Explanation:
Weight is mass times acceleration due to gravity. And hopefully you know that acceleration due to gravity on earth is 9.8 m/s^2 So what is half of that? 4.9. So now the calculation is super simple.
mass = 4 kg and acceleration = 4.9 m/s^2 so now we multiply these two numbers and get 19.6 kg*m/s^2. kg*m/s^2 is also known as Newtons, abbreviated with an N so the final result is 19.6 N.
Answer:
The coefficient of static friction between the coin and the turntable is 0.51
Explanation:
at the time of the slip:
centripetal force = frictional force
mv^2/r = x*m*980
v^2/r = 980x
x = v^2/980r
= [(120)^2]/[980*29]
= 0.51
Therefore, The coefficient of static friction between the coin and the turntable is 0.51
