a rocket takes off from Earth's surface accelerating straight up at 47.2 miles per second calculate the normal force( in N) acting on an astronaut of mass 88.9 kg, including her space suit. ( assume the rocket initial motion parallel to the +y- direction. Indicate the direction with the sign of your answer.)

By Newton's second law, the forces acting on the astronaut (the normal force n of the rocket pushing up on the astronaut, and her weight mg pulling her downward) have a net effect of

n - mg = ma

where

m = 88.9 kg

g = 9.80 m/s²

a = 47.2 mi/s² ≈ 75,960 m/s²

Then

n = m (g + a) ≈ 6.75 × 10⁶ N

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.

c) up
