Answer:
Explanation:
Consider the motion of the ball attached to string.
In triangle ABD
height gained by the ball is given as
= mass of the ball attached to string = 110 g
= speed of the ball attached to string just after collision
Using conservation of energy
Potential energy gained = Kinetic energy lost
Consider the collision between the two balls
= mass of the ball fired = 26 g
= initial velocity of ball fired before collision = ?
= final velocity of ball fired after collision = ?
using conservation of momentum
Using conservation of kinetic energy
Answer:
Current in the circuit will be 0.024 A
Explanation:
We have given battery voltage v = 6 volt
Resistance R = 220 ohm
Diode potential = 0.7 volt
So voltage across the resistance = 6 - 0.7 = 5.3 volt
Current is given by
So current in the circuit will be 0.024 A
