Explanation:
since both the teammates are of the same height, their height won't matter. Because now the basketball won't cover any vertical distance.
We have to calculate its range the horizontal distance covered by it when tossed from one teammate to the other.
range can be calculated by the formula :-
u is the velocity during its take off and is the angle at which its thrown
Given that
calculating range using the above formula
value of sin 80 = 0. 985
Hence,
Answer:
Power is the rate at which energy is transformed.
The SI unit of power is the watt.
Power is the rate at which work is done.
Explanation:
In this question we have to choose the statements related to Power that are True.
In this sense, Power is the speed with which work
is done. Its unit is Watts (
), being
.
Power is mathematically expressed as:
Where is the time during which work
is performed.
On the other hand, the Work done by a Force
refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path. It is a scalar magnitude, and its unit in the International System of Units is the Joule (like energy). Therefore, 1 Joule is the work done by a force of 1 Newton when moving an object, in the direction of the force, along 1 meter (
).
So, according to this explanation, the true statements are:
Power is the rate at which energy is transformed.
The SI unit of power is the watt.
Power is the rate at which work is done.
