Answer:
3565 J
Explanation:
F = Force applied = 1550 N
s = Displacement caused by the applied force = 2.3 m
= Angle at which the force is applied = 0°
When we multiply force, displacement and the angle at which the force is applied we get work
Work done is given by
The work done by team A is 3565 J
<span>If
the amplitude is equal to 0.25m, then the distance travelled above and below
the equilibrium is also equals to 0.25m. it means if it starts above the
equilibrium, one period will be completed when it returns back to its original
position so, it travels 0.25 below, 0.25m back, 0.25m down and o.25 m when it
comes back to its original position, so the total distance we get is by adding
0.25m 4 times that is 1m.</span>

Answer:
Power is the rate at which work is done. It is the work/time ratio. Mathematically, it is computed using the following equation. The standard metric unit of power is the Watt.
Explanation:
Answer:
Option (b) is correct.
Explanation:
The amount of heat required to raise the temperature of substance of mass 1 kg by 1 degree C, is called specific heat of the substance.
The formula of the specific heat is
H = m c (T' - T)
where, m is the mass, c is the specific heat and T' - T is the change in temperature.
So, to know the rise in temperature, by adding the known amount of heat, the specific heat is required.
So, option (b) is correct.
