Answer:

Space junk, or space debris, is any piece of machinery or debris left by humans in space. It can refer to big objects such as dead satellites that have failed or been left in orbit at the end of their mission. It can also refer to smaller things, like bits of debris or paint flecks that have fallen off a rocket.

Answer:

In addition to derelict man-made objects left in orbit, other examples of space debris include fragments from their disintegration, erosion and collisions or even paint flecks, solidified liquids expelled from spacecraft, and unburned particles from solid rocket motors. Space debris represents a risk to spacecraft.

If you want to lift a 5-kg box to a height of 2 meters, how much work must be

BlackZzzverrR [31]

Answer:100joules

Explanation:

Mass(m)=5kg

Acceleration due to gravity(g)=10m/s^2

Height(h)=2 meters

Work=m x g x h

Work=5 x 10 x 2

Work=100joules

A(n) 0.576 kg soccer ball approaches a player horizontally with a speed of 20.9 m/s. The player illegally strikes the ball with

Travka [436]

Answer:

17.6kg.m/s in the opposite direction of the initial velocity.

Explanation:

In order to solve this we can use the Impulse-Momentum theorem:

$J=\Delta p\\J=m(v_f-v_o)$

We will assume the motion of the ball approaching the player as positive, so:

$J=0.576kg((-9.73m/s)-20.9m/s)=-17.6kg.m/s$

So the impulse is 17.6kg.m/s in the opposite direction of the initial velocity.

If a school bus moves with the speed of 72km/hr, how many meters does it cover in one hour?

ELEN [110]

Explanation:

It is said that the bus moves with the speed of 72 km/hr.

It means that the bus covers 72 km in 1 hour.

so,

It covers 72 * 1000 m = 72000 m in one hour.

Hope it helps :)

I a liter jar contains 0.5 moles of gas at a pressure of 2 ATM what is the temperature of the gas

sweet [91]

Answer:

<h2>The temperature of the gas is 48.75 Kelvin.</h2>

Explanation:

Using the ideal gas equation as shown

PV = nRT where;

P is the pressure of the gas in ATM

V is the volume of the gas

n is the number of moles

R is the ideal gas constant

T is the temperature in Kelvin

From the formula, $T = \frac{PV}{nR}$

Given the following parameters V = 1litre, n = 0.5moles. pressure = 2ATM

R = 0.08206 atm L/molK

On substituting to get the temperature we have:

$T = \frac{2*1}{0.08206*0.5} \\T = \frac{2}{0.04103}\\T = 48.75Kelvin$
