An astronaut brings a cube from the earth to the moon. What is true about the inertial mass and weight of the cube?

1 answer:

6 0

When an astronaut brings a cube from the Earth to the Moon, the inertial mass remains constant, but the weight decreases.

<h3>What is the difference between mass and weight?</h3>

Mass of the body is defined as the amount of matter a body have. It is denoted by m and its unit is kg.

Weight is defined as the amount of force an object expert on the surface. It is given as the product of mass and the gravitational pull.

When an astronaut brings a cube from the Earth to the Moon, the inertial mass remains constant, but the weight decreases.Because the value of the gravitational acceleration is different on the moon.

Hence, option D is correct.

Do comets have a liquid center

Serhud [2]

Answer: Comets are basically floating chunks of ice, dust, and frozen gases. So, when comets are in space they cannot melt, So I'll say no :)

Answer - No, comets doesn't have a liquid center.

Travka [436]

Answer:

F = 183.153 N

Explanation:

given,

mass of the toothpick = 0.12 g = 0.00012 kg

initial velocity = 227 m/s

final velocity = 0 m/s

penetration depth = 16 mm = 0.016 m

using the equation of motion

v² - u² = 2 a s

0 - u² = 2 a s

- 221² = 2 × a × 0.016

a = 1526281.25 m/s²

Force is equal to

F = m a

= 0.00012 × 1526281.25

F = 183.153 N

A car is travelling at a constant speed of 26.5 m/s. Its tires have a radius of 72 cm. If the car slows down at a constant rate

maksim [4K]

Answer:

Magnitude of angular acceleration = -3.95 rad/s²

Explanation:

Angular acceleration is the ratio of linear acceleration and radius.

That is

$\texttt{Angular acceleration}=\frac{\texttt{Linear acceleration}}{\texttt{Radius}}\\\\\alpha =\frac{a}{r}$

Radius = 72 cm = 0.72 m

Linear acceleration is rate of change of velocity.

$a=\frac{11.7-26.5}{5.2}=-2.85m/s^2$

Angular acceleration

$\alpha =\frac{a}{r}=\frac{-2.85}{0.72}=-3.95rad/s^2$

Angular acceleration = -3.95 rad/s²

Magnitude = 3.95 rad/s²

Assume your mass is 60 kg. The acceleration due to gravity is 9.8 m/s 2 . How much work against gravity do you do when you climb

Andre45 [30]

Answer:

W=1705.2 J

Explanation:

Given that

mass ,m= 60 kg

Acceleration due to gravity ,g= 9.8 m/s²

Height ,h= 2.9 m

As we know that work done by a force given as

W = F . d

F=force

d=Displacement

W=work done by force

Now by putting the values

F= m g (Acting downward )

d= h (Upward)

W= m g h ( work done against the force)

W= 60 x 9.8 x 2.9 J

W=1705.2 J

Therefore the answer will be 1705.2 J.
