<span>Finite angular displacements are not vector quantities, the reason being that they do not obey the law of vector addition. This law asserts that the order in which vectors are added does not affect their sum.
However finite angles under addition tend towards commutivity as the angles become very small. Infinitesimal angles do commute under addition, making it possible to treat them as vectors.</span>

<em> Fahrenheit reading = (1.8 times Celsius reading) + 32</em> .
F = (1.8 x 232) + 32
F = 417.6 + 32
<em>F = 449.6°</em>
First, we need to fight the weight of the balls instead of their mass. We do this by multiplying their weight it kg by 9.8. This gives us .98 N. To find the potential energy of the rolling ball, we find its kinetic energy. The formula for this is KE=mass*velocity^2*1/2.
Plugging in our numbers, we have Kinetic energy = .1 * 1^2*1/2 which gives us .05 joules.
Now we find the potential energy of the ball on the shelf. For this we do:
Potential energy = .1*9.8*1, and our answer is .98 joules. Clearly, the ball on the shelf has more energy.
125 W is the power output of this machine.
Answer:
Explanation:
Power is defined as the amount of work done on the system to move that system from its original state within the given time interval. So it can be determined by the ratio of work done with time interval. As work done is the measure of force required to move a system to a certain distance. Work done is calculated as product of force with displacement.
So in the present case, the force is given as 100 N, the displacement is given as 5 m and the time is given as 4 s, then power is
As Work done = Force acting on the machine × Displacement
So
Power = =125 W
So, 125 W is the power output of this machine.
