derive relationship between commercial unit of energy and si unit of energy

is ncert solutions for computer science avalable

calculate the work required to be done to stop a car of 1500kg moving at a velocity of 60km/h?

Define 1 watt of power:

what is the relation between KW h and joules

What is the formula of sulphide ion,sulphate ion,sulphur ion ?

Q- Give one example of:-

(a) Certain force acting on a 20kg mass changes its velocity from 5m /s to 2 m/s . calculate the work done by the force .

(b) State two possible condition under which the work done would be zero.

(c) if the kinetic energy of the body is increased by 300% then determine the percentage increase in the momentum.

the power of motor pump is 2kW. how much water per minute the pump can raise to a height of 10m? (given g = 10m/s)

suggest me a working science model for class 9th

The kinetic energy of an object of mass , m moving with a velocity of 5m/s is 25J.what will be its kinetic energy when its velocity is doubled ?what will be its kinetic energy when its velocity is incrased three times

a body of mass 2 kg is thrown vertically upwards with the initial velocity of 20 m s^{-1}. what will be its potential energy at the end of 2 seconds.(g=10m s^{-2})

What is the derivation of Kinetic energy and Potential energy

What is the work done to increase the velocity of a car from 30km/h to 60km/h if the mass of the car is 1500kg?

Q1. The volume of 50g of a substance is 20cm3 . If the denstiy of water is 1 g cm3, will the substance float or sink in water ? justify your answer ?

Q2. Show that the energy of a vibrating pendulum is conserved ?

Q3. A ball is dropped from a heigh of 10m. If the energy of the ball reduces by 40% after striking the ground, how much high can the ball bounce back ?
