At what rate is the sun’s mass decreasing due to nuclear reactions? express your answer in solar masses per year.
b) find out the mass-loss rate due to the solar wind and compare.
c) assuming that the solar wind mass-loss rate remains constant, would either mass-loss process significantly affect the total mass of the sun over its entire main-sequence lifetime? (use the figure above to get an estimate of the lifetime.)

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

4900=490xh

h=10

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
