When a Lunar Module landed on the Moon, it used thrusters to slow its descent to the surface. When other spacecraft are returned

to Earth, they use parachutes to slow their descent. Why wouldn't a parachute be useful on the Moon?

A parachute is a device designed to generate a LOT of air resistance.
Parachutes do that very well in places where there's any air to work with.
There is no air on the Moon.

The magnetic field is decreasing. What is the induced electric field?
melisa1 [442]

Answer: The induced electric field will be constant i.e zero

Explanation:

Magnetic field is a region of space where magnetic force can be felt while electric field is a region of space where electric force can be felt. This two field are related because they tend to talk about force of attraction and repulsion. Example is running a current through a thin wire near a magnet, the direction of one of the field will determine the direction of the other.

According to the question, if the magnetic field is decreasing, the electric field will adjust by traveling in opposite direction to the magnetic field just to make the field constant.

If the scaled-up man now stands on one leg, what fraction of the tensile strength is the stress on the femur?.
Oksanka [162]

The fraction of the tensile strength which is the stress on the femur is 1.4%.

<h3>What is Tensile strength?</h3>

This is defined as the amount of load or stress that a material can handle before it stretches and breaks.

The femur which is located in the thigh is the largest bone in the body and it exerts a fraction of 1.4% tensile strength through the stress encountered on the femur when the man stands with one leg.

The old-fashioned record player had two speeds: one for long-playing albums (LP) and one for singles. The turntable speed for LP
eimsori [14]

Answer:

\alpha = 0.305 rad/s^2

Explanation:

initial frequency of revolution is given as

f_1 = 100/3 rpm

now initial angular speed is

\omega_i = 2\pi f

\omega_i = 2\pi(\frac{100}{3\times 60})

\omega_i = 3.49 rad/s

Similarly final angular speed is given as

\omega_f = 2\pi f_2

\omega_f = 2\pi(\frac{45}{60})

\omega_f = 4.71 rad/s

Now angular acceleration is given as

\alpha = \frac{\omega_f - \omega_i}{\Delta t}

\alpha = \frac{4.71 - 3.49}{4}

\alpha = 0.305 rad/s^2
