Answer:
Hi myself Shrushtee.
Explanation:
The fuse is connected to the live wire so that the appliance will not become charged (have a potential difference of 230 V) after the fuse has melted due to excessive current. Fuses must be fitted onto the live wire so that when it blows, it will disconnect (isolate) the appliance from the high voltage live wire.
Answer:
m v^2 / R = m g where gravitational force provides centripetal force
R = v^2 / g = 14.3^2 m/s / 9.8 m/s^2 = 20.9 m
Explanation:
d = Diameter of wheel = 27 cm
r = Radius = 
m = Mass of wheel = 800 g
= Initial angular velocity = 
Equation of rotational motion

Moment of inertia is given by

Torque is given by

C is incorrect because the atomic number and symbol are the only ones displayed.
I think it could be A but it is most likely C
Hope it helps!!
Answer:
2000J
Explanation:
work done = force * distance
Work done = 100 * 20
Work done = 2000J
