What is the magnetic force on a proton that is moving at 3.8 x 10^7m/s up
through a magnetic field that is 0.72 T and pointing toward you? The charge
on a proton is 1.6 x 10-19 C. Use F = qvx B sine.

b) phosphorus pentoxide

force tends to be low and long diustance masses are high

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
