The acceleration due to gravity on the Moon's surface is
Molodets [167]

Answer:

50 lb

Explanation:

Given,

The weight of astronaut's life support backpack on Earth (w) = 300 lb

Acceleration due to gravity on Earth (g) = 9.8 m/s²

Acceleration due to gravity on Moon = g'

g'=\frac{g}{6}

We know that weight of an object on Earth is,

w = m\times g

m = \frac{w}{g}

Similarly, weight on Moon will be

w' = m\times g'

w' = \frac{w}{g}\times\frac{g}{6}

w' = \frac{300}{6}

w' = 50

Thus the astronaut's life support backpack will weigh 50 lb on Moon.

For Mass

K.E = (1/2*mv^2)

Explanation:

Kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

On which variable does magnetic flux depend?A) the magnetic fieldB)the orientation of the field with respect to the region throu
hram777 [196]

Answer:

D) All of these

Explanation:

The magnetic flux through a coil of wire is given by:

\Phi = BA cos \theta

where

B is the intensity of the magnetic field

A is the area enclosed by the coil

\theta is the angle between the direction of B and the normal to the area of the coil

Therefore, we see that the magnetic flux depends on all these quantities:

A) the magnetic field

B)the orientation of the field with respect to the region through which it passes

C)the area of a region through which magnetic field passes

So, the correct answer is

D) All of these
