Mechanical energy is the top because it has two types.
These two types are:
Kinetic energy - which is the energy in motion and potential energy which is the energy in reserve.
Both energy in motion and reserve is called Joules. Joules is the International System of Measurement unit for energy, this is mainly used for scaling energy in all aspects.
Answer:
D, the acceleration of A is twice that of b.
Explanation: in four seconds b got to ten, in two seconds a got to 20. Going 10m/s faster in half the time is going twice the acceleration
The MCB of a rupas room is tripped and keeps on tripping again and again, and if it is a domestic circuit, what could be the reason for this phenomenon?
The reason could be a short circuit which is resulting in higher level of currents to pass through the MCB which is resulting in trip every time.
OR
The MCB is faulty and might need a replacement.
To Diagnose the problem further more.
Turn off all the switches in rupas room and then try turning on the MCB. If it trips again then MCB is faulty (Subjective to the fact there everything was normal before this issue and no signs of short circuit or spark in wiring were observed)
If MCB does not trip in point 1 then Turn ON all the switches one by one. This shall give you the cause of problem.
Explanation:
a) The Earth makes 1 rotation in 24 hours. In seconds:
24 hr × (3600 s / hr) = 86400 s
b) 1 rotation is 2π radians. So the angular velocity is:
2π rad / 86400 s = 7.27×10⁻⁵ rad/s
c) The earth's linear velocity is the angular velocity times the radius:
40075 km × 7.27×10⁻⁵ rad/s = 2.91 km/s
<span>On the ignition switch, the
ACC position provides power to electrical equipment including lights, wipers, warning lights and radio, without turning on the engine.

ACC is an Autonomous cruise
control or adaptive cruise
control is a system for
road vehicles that automatically adjusts the vehicle speed (can increase or
decrease the speed) to maintain a safe distance from vehicles ahead.
There are
also many other names of Autonomous cruise control such as active cruise control, intelligent cruise
control, or radar cruise control.
