Answer:
The acceleration of the ball as it rises to the top of its arc equals 9.807 meters per square second.
Explanation:
Let suppose that maximum height of the arc is so small in comparison with the radius of the Earth.
Since the ball is launched upwards, then the ball experiments a free-fall motion, that is, an uniform accelerated motion in which the element is accelerated by gravity. Then, the acceleration experimented by the motion remains constant at every instant and position.
Besides, the gravitational acceleration in the Earth and, in consequence, the acceleration of the ball as it rises to the top of its arc equals 9.807 meters per square second.
In hot warter or substant bc hot makes molecues go,s faster then all the rest
Weather is the condition of the atmosphere at a particular place and time
Climate is the average condition of the atmosphere of a specific place over a long period of time
Dropping two objects and seeing them hit the ground at the same time
A. 75 ampere-turns
<u>Explanation:</u>
Given:
Number of turns, n = 50
Voltage, V = 9V
Current, I = 1.5A
MMF= ?
MMF is magnetomotive force.
MMF is independent on voltage and dependent on the number of turns and current in the wire.
Thus, MMF can be written as:
On substituting the value we get:
MMF = 50 X 1.5
MMF = 75 ampere-turns
