Scientists conduct multiple trial experiments because one test might not be as reliable as multiple trials. Another reason they conduct multiple trials is because the scientific method says to conduct multiple experimental tests.
Answer:
voltage is 1.38 V
Explanation:
given data
weights = 150 gm = 0.150 kg
sensitivity = 0.5 volts/Newton
to find out
large a voltage
solution
we know here in by symmetry so here in x axis
F3 will be
F3 = 2mgcos(20)
F3 = 2(0.150)(9.8)cos20
F3 = 2.76 N
so volatge is
voltage = 2.76×sensitivity
voltage = 2.76×0.5
voltage = 1.38
so voltage is 1.38 V

Material from the early solar system that was never transformed into a planet is now left over in space. After the planets formed, particles collided and created space debris.
Radiation pressure from the sun and the powerful solar wind both helped to expel the gas from the solar nebula. By the end of the Heavy Bombardment period, part of the residual debris had been removed from the nebula. The nebular hypothesis is the theory of planetary creation that is most widely accepted. According to this theory, the Solar System was created 4.6 billion years ago as a result of the gravitational collapse of a massive molecular cloud that stretched across several light-years.
