Hello I hope you are having a great day :)
Your question: When a light switch is turned on, the light comes on immediately because....
The answer is: the electrons in the wire are instantly "pushed" by a voltage difference making the the light switch on.
Hopefully that helps you :)
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
The answer is <span>A) Velocity describes speed with direction.
Speed can be in any direction </span>
Answer: 21 kg x m/s
Momentum can be found using the equation p = mv, or momentum = mass times velocity.
Therefore, to find the momentum of the bowling bowl, you can plug the mass and velocity values into the equation to get p = (7kg)(3m/s)
Solve the equation to get a momentum of 21kg x m/s
I hope I could help :)
