If a substance has a density of 2.7g/cm3 and a mass of 86.4g, what is its volume?

Answers

Answer:

32cm³

Explanation:

Given parameters:

  Density of substance  = 2.7g/cm³

   Mass of substance  = 86.4g

Unknown:

Volume of substance  = ?

Solution:

Density is the mass per unit volume of a substance.

    Density  = [tex]\frac{mass}{volume}[/tex]

Since the unknown is volume we solve for it;

   mass  = density x volume

   86.4 = 2.7 x volume

    volume  = [tex]\frac{86.4}{2.7}[/tex]   = 32cm³

Meteorites float in space, meteors move through the atmosphere, and meteoroids have landed on the surface. Meteors float in space, meteorites move through the atmosphere, and meteoroids have landed on the surface. Meteoroids float in space, meteors move through the atmosphere, and meteorites have landed on the surface.

Answers

Answer:

D.

Explanation:

A meteoroid is a piece of stony debris that float in space and move around the sun in different orbits and speeds.

Meteoroids enter into Earth's surface with a high speed as shooting stars and called meteors. Meteors move through the atmosphere and landed on the surface and it is called a meteorite.

Hence, the correct answer is "D."

An object weighs 530.0 Newton. It is being pushed along a horizontal surface by a 340.0-
Newton force. Determine the mass of the object. Enter a numerical answer.

Answers

Answer:

54.08 kg

Explanation:

The weight of an object is the force of gravity acting on the object and is related to the mass of the object as;

Weight = mass x acceleration due to gravity (g), where g = 9.8 m/s.

Hence, the weight of the object is only dependent on its mass and g, not on any other force. Now, if the weight is 530.0 N,

530 = m x 9.8

   m = 530/9.8

                = 54.08 kg

Therefore, the weight of the object is 54.08 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 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

The potential energy that depends on height is called gravitational potential energy. (Option B)

What is gravitational potential energy?

Gravitational potential energy is a form of potential energy that an object possesses due to its position relative to a gravitational field.

When an object is raised to a certain height above the ground, it gains gravitational potential energy. The higher the object is raised, the greater its potential energy.

This potential energy is a measure of the work that would be required to move the object against gravity and bring it back down to its original position.

The formula for gravitational potential energy is;

Potential Energy (PE) = mg h

where;

PE is the gravitational potential energym is the mass of the objectg is the acceleration due to gravityh is the height or elevation of the object

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.

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.

What factor is likely most responsible for the changes observed in the world's rainforests? a. volcanic activity b. human activity c. temperature changes d. solar eclipses Please select the best answer from the choices provided A B C D

Answers

Answer:

b

Explanation:

The factor that is most likely to be responsible for the changes observed in the world's rainforest is human activities.

There has been a surge in the human population leading to an increased need for housing, foods, and other infrastructures. All these needs are directly or indirectly provided by the forest. Hence, the more the population of human expands, the more pressure that would be exerted on the rainforest and, indeed, other forests of the world.

The correct option is b.

Answers

Answer:

   h = 2,9002 10⁴ ft

Explanation:

Scientific notation is a method to write very large and small numbers clearly, the figure is written with an integer and the other figures in decimals, with an exponent so that the number does not change.

If it is necessary to approximate a figure, the criterion is if the next figure is greater than or equal to five, the figure rises by one unit.

Mount Everest height

 

    h = 29002 ft

    h = 2,9002 10⁴ ft

if we approximate three significant figures that

     h = 2.90 10⁴ ft

Answer:

[tex]2.9002 \cdot 10^{4} ft[/tex]

Explanation:

To express the height 29,002 in scientific notation we need to move the decimal point four places to the left and express the answer into a base-ten power, as follows:

[tex]29,002 = 2.9002 \cdot 10^{4}[/tex]

The answer expressed in scientific notation results in 2.9002 times a ten to the fourth power, as a result of the four movements of the decimal point.

A 55 kg boy is throwing a 0.23 kg baseball up in the air. He decides to see how high he can throw it and uses a timer to see how long the ball stays in the air. He throws the ball as hard as he can straight up in the air and finds that it takes 5.5 seconds to come back to him. How long did it take for the ball to reach its highest point? (half the time it was in the air)

Answers

Answer:

2.75 s

Explanation:

From the question given above,

Total time (T) spent by the ball in air = 5.5 s

Time taken (t) to reach the greatest height =...?

Thus, we can obtain the time taken (t) for the ball to reach the greatest height as follow:

T = 2t

Where:

T is the total time spent by the ball in air.

t is the time taken to reach the greatest height

Total time (T) spent by the ball in air = 5.5 s

Time taken (t) to reach the greatest height =...?

T = 2t

5.5 = 2 × t

Divide both side by 2

t = 5.5/2

t = 2.75 s

Therefore, the time taken (t) to reach the greatest height is 2.75 s.
