Question

please solve this.......

Answer 1

1) 1C=273K

Therefore,300K=27C,

And,-10C=263k.

2) It's about force to mass and distance in Newton's law of gravitation.

3) Ice, it has latent heat of fusion subtracted from that of water at 0 degrees Celsius .So ice has more cooling effect .

4) Total distance will be 3km+2km+3.5km

=8.5km

Displacement can be found out using Pythagorean theorem

Displacement ²=2²+6.5²

Displacement=√4+42.25

Displacement=√46.25=6.8(approx)

Hope it helps ☺
