Answer:
the angular acceleration of the gate is approximately 1.61 
Explanation:
Recall the formula that connects the net torque with the moment of inertia of a rotating object about its axis of rotation, and the angular acceleration (similar to Newton's second law with net force, mass, and linear acceleration):
In our case, both forces contribute to the same direction of torque, so we can add their torques up and get the net torque on the gate:
Now we use this value to obtain the angular acceleration by using the given moment of inertia of the rotating gate:
Explanation:
Coal and natural gases are fossil fuels that are found in geologic formation. They both form under similar environment of high temperature and pressure which transforms organic matter.
Natural gas is a fluid and coal is a solid.
How did they form differently?
- Natural and gas and petroleum are both derived from an organic matter rich in both plant and animal remains.
- Coal is typically derived from organic matter that is rich in only plant remains usually formed in swampy area.

In one of the greatest coincidences to arise on Brainly in quite some time, Choice-C is the correct choice for BOTH #15 and #16 .
Choice-C is the only situation in which the source is a different distance from each ear.
Answer:
the ball experiences the greater momentum change
Explanation:
You have to take into account that momentum change is given by
where vf and vb are the speed of the object after and before the impact.
In the case of the ball you have
where the minus of vf is included due to the motion is in an opposite direction regarding with vb
And for the lump
Hence, the ball experiences the greater change
hope this helps!!
