Cathode ray tube, plumb pudding model, atoms were not hard spheres, but had smaller parts.
Pressure is defined as the force per unit area. This measurement is more convenient to use for describing a force exerted. The standard unit for pressure is Pascal. For this problem, force is the gravitational pull from the block. Calculations are as follows:
P = F/A where F = mg
F = 7.5 ( 9.81) = 73.6 N
<span>P = 73.6 N / 0.6 m^2 = </span><span>122.5 Pa
Thus, the answer is D.</span>
The answer should be A because it’s frequency of a sound per second
Answer:
oh I know that sounds good to me
Answer:
