then why a powefull lazer beam can not move a small mass.

Secondly how anything that travel at "C" can have a mass ?

please note light propulsion works on combustion of air not momenum

According to the equation E=mC2 (Note: '2' stands for 'squared'), mass is changed into energy. This energy will surely heat the Earth up, wouldn't it? I can't find proof for it. Please help.

Second Question:
A string fastened at both ends has successive resonances with wavelengths of 0.57 m for the nth harmonic and 0.50 m for the (n + 1)th harmonic.
What is the value of n? and What is the length of the string?

If you could please show me how to do it then that would be great, thanks!

Hi! Before I begin, thanks for reading this question and even bigger thanks if you answer! I'm in the middle of a Physics Investigation and one of the minor things that I need to include are the properties of a few different materials. So far I've been ok at doing this but have become stuck at cling film and sand paper (!) can you help please? I need to discuss their surfaces and how easily air would pass over them. Thanks again!

A body is suspended vertically from an ideal spring of spring constant 2.5 n/m. the spring is intialily in its relaxed position. the body is then released and oscillates about it equilibrium position. the motion is described by y=(4.0cm)sin{(0.70rad/s)f}

what is the maximum kinetic energy of the body?
