Question

1) From which element do we get atomic energy? 2) One car travels 300 kilometres from Mumbai to Ratnagiri in 6 hours. What will be its speed? 3) What should be taken in account for measuring work 4) Define - weight.​

Answer 1

Answer:

Explanation:

1. uranium

2.distance = 300km time = 6 hours

speed = distance / time = 300/6 = 50km/hr

3.mass of body

4.the gravitational force exerted by a body

Answer 2

Answers for the following questions

Explanation:

1)From which element do we get atomic energy?

Explanation:

• Uranium is the most often utilized element for nuclear atomic energy
• This is due to the ease with which uranium atoms split apart.
• However, the sort of uranium utilized to make nuclear energy, known as U-235

2) One car travels 300 kilometres from Mumbai to Ratnagiri in 6 hours. What will be its speed?

Given:

Distance d = 300km

Time t = 6 hrs

Explanation:

As we know,

SPEED = DISTANCE/TIME

now,

Speed =300/6 = 50 km/hr

hence, the required speed is 50 km/hr

3) What should be taken in account for measuring work

Explanation:

Force and Displacement should be taken into account while measuring Work.

             Work = Force × Displacement

                  W = F X S

4) Define - weight.​

Explanation:

weight:

• force of gravity on the object of an object is known as weight

• SI unit of weight is Newton (N)
