Answer:
m/s
km/h
mph
Explanation:
speed is measured with distance which does in velocity too that is why I chose this answer
Answer:
T - M g - Ff = M a describes the acceleration of the object
T = M g + Ff if the object moves at constant speed (a = zero)
Ff = μ M g = .3 * 40 * 9.8 = 118 N the force of friction
Ff will be in a direction opposite to the motion
M g = 40 kg * 9.8 m/s = 392 N
a) T = M g + Ff for an object moving upwards
T = 392 + 118 = 510 N
b) T = M g - Ff for an object moving downwards
T = 392 - 118 = 274 N
A nuclear power plant is defined as a thermal power station where electricity is generated by the help of sustainable nuclear fission.
A nuclear power plant needs nuclear reactor as the thermal energy generator .The reactor has various parts where fissionable radioactive material will undergo nuclear fission .Through this process high amount of thermal energy is released which is allowed to water to generate steam.
The steam produced in the reactor drives the turbine which is connected to the generator.Due to the electromagnetic induction the generator will produce electricity.
The control rods present in the nuclear reactor will control the rate of fission by absorbing the thermal neutrons.
Hence the correct answer of the question is C i.e Turbine.
Answer:
C. 500 watts
Explanation:
power is defined as the rate of work done
When a force causes a object to move, work is being done on the object by the force.
Answer:
1.03m/s
Explanation:
According to the question
Fdrag = bv²
now Fdrag = weight of the box
that is Fdrag = mg
where m = mass of the box, 0.6 Kg
and g = acceleration due to gravity
thus,
Fdrag = bv² becomes
mg = bv²
making v the subject of formula
v = 1.03m/s
