Answer: Electromagnetism and sound
Answer:
117,30m
Explanation:
I think the situation here is a horizontal projection to the ground. So in order to find the distance the formula = Ut, where U is the initial speed and t is the Time of flight. To get the time of flight in this case =√2h/g where h is the height and g is gravity. so to get the time = √2×300÷9.81 =7.821 .so range =ut which is equal to the time multiplied by 15m/s =117.30m
Explanation:
Centripetal acceleration is the acceleration caused by centripetal force. It is equal to the square of the tangential velocity divided by the radius of the circular path.
a = v² / r
Answer:
-10.0 cm
Explanation:
OK so in the equation they're having you use the variables are:
So we simply plug in the variables:
There's no way to tell without seeing the diagram.
