An space probe built on Earth has a mass of 750 kg. Calculate the weight of the space probe on Earth.

Answers

Answer 1

Answer:

7357.5N

Explanation:

Weight is the force used to pull a mass of object towards the centre of the Earth. The force is 9.81 N/kg.

so, Weight = mass × 9.81

the weight of the space probe should be: 750 × 9.81 = 7357.5 N

Answer 2

Answer:

7350N

Explanation:

Data

m-750kg

g-9.8

W=mg

=750 x 9.8

=7350N

A spray gun, used to apply paint, uses Bernoulli's principle to function. It contains two tubes inside of it: one tube comes up from the supply of paint and one supplies a flow of compressed air that blows across the top of the paint tube. This rush of air creates ____, which sucks the paint up the tube and into the stream of air.

Answers

Answer:

Low pressure

Explanation:

Take two nearby points at the junction of both the tube, let point 1 be in the air tube while point 2 be in the paint tube.

According to Bernoulli's principle, the air at point 1 is moving with some speed which causes the pressure drop inside tube 1, while at point 2 there is no velocity, so there is no pressure drop at that point. In fact, the pressure at point 2 approximately equals the atmospheric pressure.

As both the points are taken is nearby at the junction, to the pressure drop in the flow air pipe causes the suction of fluid from the relatively high-pressure tube (paint tube).

Hence, this rush of air creates low pressure, which sucks the paint up the tube and into the stream of air.

How can Newton's third law describe the forces affecting a rocket as it
descends to Earth's surface?
A. The rocket pushes through the air with a force equal to that of
Earth's gravity pulling on the rocket.
B. The maximum amount of force the rocket engines can provide
determines how much mass the rocket can lift.
C. The force the rocket exerts on the air is in the direction opposite to
the force that the air exerts on the rocket.
D. The rocket can move downward because the forces acting on it
are unbalanced.

Answers

Answer:

C

Explanation:

The force the rocket exerts on the air is in the direction opposite to

the force that the air exerts on the rocket.

Newton's third law describe the forces affecting a rocket as it descends to Earth's surface because: C. The force the rocket exerts on the air is in the direction opposite to  the force that the air exerts on the rocket.

Newton's Third Law of Motion states that for every action there exist an equal but opposite reaction.

This ultimately implies that, Newton's Third Law of Motion is a law that is generally based on action-reaction force pairs.

Generally, action-reaction force pairs make it possible for;

Birds to fly.Kicking a ball.Rowing a banca.Cars to move.Objects being in motion.Fishes to swim.Throwing a stone.Rockets descending to Earth's surface.

Based on Newton's Third Law of Motion, the force a rocket exerts on the air is in the direction opposite to the force that the air exerts on the rocket.

What is radioactivity?

The nucleus of an atom exhibits the phenomenon of Radioactivity due to its instability. Energy will be lost due to the emission of radiation from the unstable nucleus of an atom.

The electrostatic force of repulsion and the powerful forces of attraction keep the nucleus together. The instability increases as the size of the nucleus increases because the mass of the nucleus increases when concentrated. Therefore, Plutonium, Uranium is extremely unstable and undergoes radioactivity.

The emitted radiation from radioactivity always consists of alpha, beta, and gamma particles. Gamma Decay is photons having high energy, Beta Decay consists of Electrons while Alpha Decay consists of a Helium nucleus.

A force of 49N causes a box to move with an acceleration of 7m/s2. Find the mass of the object

Answers

Answer:

The answer is 7 kg

Explanation:

To find the mass of the object given the force and acceleration we use the formula

[tex]m = \frac{f}{a} \\ [/tex]

where

f is the force

a is the acceleration

m is the mass

From the question

f = 49 N

a = 7 m/s²

We have

[tex]m = \frac{49}{7} \\ [/tex]

We have the final answer as

7 kg

You throw a ball straight up into the air at a velocity of 15 m/s. You want to know how high above your hand the ball will be at exactly 2.5 sec after you released it. You must SHOW ALL WORK to receive credit!!! Of the 5 motion variables - Vi, Vf, a, ΔX, and T, identify which one you are solving for and the magnitudes and directions of all of the others that are known: Which of the motion equations is best to use to determine the height of the ball? How high is the ball above your hand at 2.5 sec after you throw it?

Answers

Answer:

6.875m

Explanation:

Given

Velocity = 15m/s

Time = 2.5secs

Required

Distance above your hand the ball will be at exactly 2.5secs

using the equation of motion:

ΔX = ViT + 1/2aT²

ΔX is the distance

Vi is the velocity of the ball in air

a is the acceleration due to gravity

T is the time taken

Since the ball is thrown straight up, a = -g

ΔX = ViT - 1/2gT²

Substitute

ΔX = 15(2.5) - 1/2(9.8)(2.5)²

ΔX = 37.5-30.625

ΔX = 6.875m

Hence the ball will be 6.875m above your hand at 2.5secs after you throw it.

A tennis ball with a speed of 11.5 m/s is moving perpendicular to a wall. After striking the wall, the ball rebounds in the opposite direction with a speed of 5.842 m/s. If the ball is in contact with the wall for 0.0129 s, what is the average acceleration of the ball while it is in contact with the wall? Take "toward the wall" to be the positive direction. Answer in units of m/s 2

Answers

Answer:

1344.34 m/s

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 11.5 m/s

Rebound velocity i.e final velocity (v) = 5.842 m/s

Time (t) = 0.0129 s

Acceleration (a) =.?

The acceleration of the ball while it is in contact with the wall can be obtained as follow:

a = (v + u) / t

a = (5.842 + 11.5) / 0.0129

a = 17.342 / 0.0129

a = 1344.34 m/s

Therefore, the average acceleration of the ball while it is in contact with the wall is 1344.34 m/s

When a body like earth is moving in a circular path the work done in that case is zero because: (a) Centripetal force acts in the direction of motion of the body (b) Centripetal force acts along the radius of circular path (c) Gravitational force acts along the radius of circular path (d) Centrifugal force acts perpendicular to the radius of circular path

Answers

Answer:

(b) Centripetal force acts along the radius of circular path

Explanation:

Centripetal force is a force experienced by a body moving in a circular path. It is expressed mathematically ad F = mv²/r

m is the mass of the body

v is the velocity

r is the radius of the circular path

When a body moves in a circular path, work dome is zero because Centripetal force acts along the radius of circular path and the force is at right angle with the motion of body.
