3a) w = mg = 60 x 10 = 600N
b) W = fd = 600 x 10 = 6000J
c) chemical to gravitational potential via the mechanical pathway

4a) W = fd = 200 x 0.5 = 100J
b) chemical to kinetic via mechanical pathway

5a) F = W/d = 40000/20 = 2000N
b) some is transferred into the thermal store, some is dissipated into the surrounding

An atomic physicist determines that an atom is composed of 8 positively charged particles and has a mass of 15 amu. which is the

stellarik [79]

<span> 1.the atom has 7 neutrons and 8 protons....

because the positively charged particles are the protons ...and 8 is also the atomic number ...so number of neutrons can be calculated by subtracting </span>atomic number from the mass number...which gives us the neutrons 7 ...

Hope it helps !!!
