Yes it is possible to do that

**Answer:**

v = 1.28 m/s

**Explanation:**

**Given that,**

Maximum compression of the spring,

Spring constant, k = 800 N/m

Mass of the block, m = 0.2 kg

**To find,**

The velocity of the block when it first reaches a height of 0.1 m above the ground on the ramp.

**Solution,**

When the block is bounced back up the ramp, the total energy of the system remains conserved. Let v is the velocity of the block such that,

**Initial energy = Final energy**

Substituting all the values in above equation,

**v = 1.28 m/s**

Therefore the velocity of block when it first reaches a height of 0.1 m above the ground on the ramp is 1.28 m/s.

Momentum = (mass) x (speed)

= (2 kg) x (5 m/s)

= **10 kg-m/s**

No. Atom cannot exist without a nucleus. There would be only one part in an atom if nucleus would be deleted and that will be "Electrons", when electrons will be alone they will be just electron not an atom.

**In short, Atom can't exist without a nucleus**

Hope this helps!

When an earthquake strikes usually seismic waves carry the energy outward (a.) With the greatest power at the focus and as the seismic waves travel outward they become more and more weak until they disappear.<span />
