A bullet loses `1/20` of its velocity in passing through one plank What is the minimum number of plank's required to stop the ballet:

A

5

B

10

C

11

D

20

Text Solution

Verified by Experts

The correct Answer is:
c
If bullet loses 1/nth of its velocity in passing through one plank then minimum no. of planks required is `((n)/(2)+1)=(20)/(2)+1=1`

A rifle bullet loses half of its velocity in penetrating 24 cm in a wooden plank. The further distance covered by the bullet in coming to rest is:

The blades of a windmill sweep out a circle of area 30m^(2) . If the wind flows at a velocity 10ms^(-1) at right angles to the circle, what is the mass of the air passing through it in time t? What is the kinetic energy of the air? If the density of air is 1.2 kgm^(-3) , then calculate the electric power produced if the windmill converts 25% of wind energy into electrical energy.

A parallel plate capacitor is to be designed with a voltage rating 1 kV, using a material of dielectric constant 3 and dielectric strength about 10^(7) Vm^(-1) . (Dielectric strength is the maximum electric field a material can tolerate without breakdown, i.e., without starting to conduct electricity through partial ionisation.) For safety, we should like the field never to exceed, say 10% of the dielectric strength. What minimum area of the plates is required to have a capacitance of 50 pF?

A bullet travelling at 200ms^(-1) penetrates a wooden block of thickness 0.20 m and comes out at 20ms^(-1) . Calculate the retardation produced inside the block. What additional thickness is required to stop the bullet.

In a hydrogen atom, the electron and proton are bound at a distance of about 0.53 Å (a) Estimate the potential energy of the system in eV, taking the zero of the potential energy at infinite separation of the electron from proton. (b) What is the minimum work required to free the electron, given that its kinetic energy in the orbit is half the magnitude of potential energy obtained in (a)? (c) What are the answers to (a) and (b) above if the zero of potential energy is taken at 1.06 Å separation?

A bullet moving with a speed of 100 ms^1 can just penetrate two planks of equal thickness. Then, the number of such planks penetrated by the same bullet when the speed is doubled will be
