An space probe built on Earth has a mass of 750 kg. Calculate the weight of the space probe on Earth.
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:
7350N
Explanation:
Data
m-750kg
g-9.8
W=mg
=750 x 9.8
=7350N
All of the matter present at the beginning of a chemical reaction will still be present at the end of a chemical reaction, although possibly in a different form or substance. This is because of the...
A. Law of conversation of energy
B. Law Of Universal Gravitation
C. Law Of Conversation Of Mass
D. Ohms Law
Answer:
C. Law Of Conservation Of Mass
Explanation:
In this scenario, this would occur due and is explained by the Law of Conservation of Mass. This law basically states that the mass that exists during and after a chemical reaction must remain the same, assuming that the reaction is taking place in a closed environment where no loss of mass is occurring. This means that if the reaction is in a closed environment the mass should not change whatsoever even if it is not in the same form or substance as it was before the reaction occurred.
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.
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.

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
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

why are force and velocity different?
Answer: If you apply force to an object the velocity changes. But it doesn't work the other way around apply velocity and the force (no!) Velocity does not change on an object. A force pushes or pulls on an object, but velocity is simply something an object has I hope this makes sense to you. Hope this helps :)

why might a CD be a more reliable way to copy and distribute a sound recording than a vinyl record
Answer:
Is either b or d
Explanation:
A CD be a more reliable way to copy and distribute a sound recording than a vinyl record because a CD is easier to copy exactly over and over again.
What are CDs and vinyl records?CDs are digital music storage devices, which means the music is binary data encoded. It uses a 2-channel, 16-bit, 44.1 kHz configuration as the norm for CDs. A laser reads the data, and after it has been decoded, audio is played back.
A sensitive needle known as a stylus is used to read the physical record of the music that is imprinted on the vinyl disc because vinyl is an analogue storage medium. The 12-inch 33-rpm LP, 7-inch 33-rpm EP, and 7-inch 45-rpm single make up the typical vinyl album.
The diameter and playback speed are what determine a vinyl disc's storage capacity (larger discs and slower playback means more capacity). The stereo channels are divided among the groove's two sides.
Hence, option (D) is correct.

B. 6kg
C. 8kg
D. 14kg
Answer:
A
Explanation:
We know the force is (16N-12), which is 4N, and we know the acceleration is 2 m/s^2. Meaning, we can solve the formula m = F / a (mass equals force divided by acceleration), and we get 2kg.

How do you find the distance a object has traveled
Answer: Got this from a web search... Change the answer up a bit
Explanation:
The distance travelled is the path taken by a body to get from an initial point to an end point in a given period of time, at a certain velocity. If the velocity is constant: Distance = time * velocity. d = v*t.
Answer:
I researched and found it to be TIME * VELOCITY ( d= v*t)
Explanation:
When I use * I just mean multiply. So its time 'multiplied by velocity' in order to get 'distance'

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.
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.

You have about 10 quarts of blood in your body. At REST your heart pumps about 5 quarts each minutes. That is half of your blood volume per minute. During exercise it can pump 40 quarts per minute. How many times does all of your blood complete the cycle around your body during exercise?
Answer:
8 times
Explanation:
Given that You have about 10 quarts of blood in your body. At REST your heart pumps about 5 quarts each minutes.
That means the heart will pump 10 quarts in 2 minutes.
That is half of your blood volume per minute.
If during exercise it can pump 40 quarts per minute, that is, 80 quarts in 2 minutes.
To know how many times does all of your blood complete the cycle around your body during exercise, you must divide 80 quarts by 10 quarts. That is,
80 / 10 = 8
Therefore, your blood complete the cycle around your body 8 times during the exercise.
