<h2>What is an electric fuse?</h2><h3>
Answer: Electric fuse is a safety device used to limit the current in an electric circuit which melts and breaks the circuit whenever there is an excess flow of current through the circuit.</h3><h2>What is the working principle of electric fuse?</h2><h3>An electric fuse is based on the principle of heating effect of electric current. It is made up of thin metallic wire of non-combustible material. A fuse is always connected between the ends of the terminal in a series connection with the circuit.</h3>
Answer:
91.64 km
91.64 km high material would go on earth if it were ejected with the same speed as on Io.
Explanation:
According to Newton Law of gravitation:
Where:
G is gravitational constant=
For Moon lo g is:
According to law of conservation of energy
Initial Energy=Final Energy
For Jupiter's moon Io:
Velocity is given by:
For Earth Velocity is given by:
Now:
91.64 km high material would go on earth if it were ejected with the same speed as on Io.
Answer:
v = 8.57 m/s
Explanation:
As we know that the wagon is pulled up by string system
So the net force on the wagon along the inclined is due to tension in the rope and component of weight along the inclined plane
So as per work energy theorem we know that
work done by tension force + work done by force of gravity = change in kinetic energy
so we have
m = 38.2 kg
d = 85.4 m
so now we have
Answer:
Answer below!!
Explanation:
Every observer would observe the same image location and every light ray would follow the law of reflection.Yet only two of these rays would be needed to determine the image location since it only requires two rays to find the intersection point.
Hope I helped!!
