Answer:

follows are the responses to the given question:

Explanation:

The kinetic energy of every object moving.  [tex]PK=m \times v^2[/tex] any entity lifted against the strength of gravity stores elastic potential of gravity.

[tex]PE = height \times mass \times g[/tex]

Its total power of an independent device stays constant underneath the Mass conservation on Energy and it is, the kinetic energy plus potential energy is just like a fixed [tex](KE+PE=Standard)[/tex]. So, if KE improves, it is valid that PE declines.

If the PE is now at least then KE has been at the highest. It is also valid that KE is reduced as PE is increased as well as the maximum PE, the minimum KE.

Answer:

8.6 m/s

Explanation:

From the question,

applying law of conservation of momentum

Total momentum before collision = Total momentum after collsion

mu+m'u' = mv+m'v'....................... Equation 1

make v' the susbject of the equation

v' = (mu+m'u'-mv)/m'.................. Euqation 2

Where m = mass of the ball, m' = mass of the can, u = initial velocity of the ball, u' = initial velocity of the can, v = Final velocity of the ball, v' = final velocity of the can.

Given: m = 1.2 kg, m' = 0.7 kg, u = 14 m/s , u' = 0 m/s (at rest), v = 9 m/s.

Substitute these values into equation 2

v' = [(1.2×14)+(0.7×0)-(1.2×9)]/0.7

v' = (16.8-10.8)/0.7

v' = 6/0.7

v' = 8.6 m/s

Answer:

Velocity

Explanation:

In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain.

Explanation:

Answer: No , a chemical change has not occured as it was easily reversed.

Explanation:

Chemical change is defined as a change in which rearrangement of atoms take place and leads to formation of new substances. It can only be reversed with the help of a chemical reaction.

Physical change is defined as a change which leads to change in shape, size or state of the substance changes. No new substance is formed.It can be easily reversed.

As the hair colour was washed out and returned to its original brown colour, it was a physical change.

Answer:

I guess it's force hope this answer helps

Answer:

Kindly check explanation

Explanation:

Motion of an object could be explainwd as how a body changes position over time. Some of the proven facts about motion are stated by Sor Isaac Newton, named the Laws of motion :

1. A body will continue on it's state of rest or uniform motion in a straight line unless acted upon by a force to make it act otherwise.

2.) The second law explains that the force acting in an object is a product of the mass and acceleration.

Force = mass * acceleration due to gravity

3.) To every action, there is an equal and opposite reaction.

That is ; applied force in the positive direction on an object, yield an equal amount of force in the opposite direction.

Answer:

f=force m=mass and a=acceleration

hiiiiiiiiiiiiiiiiiiii

Answer:

1- when carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating

2-Human activities emit 60 or more times the amount of carbon dioxide released by volcanoes each year. ... In fact, several individual U.S. states emit more carbon dioxide in a year than all the volcanoes on the planet combined do. On the scale of carbon dioxide emissions, human sources far outweigh volcanoes

3-Human activities such as the burning of oil, coal and gas, as well as deforestation are the primary cause of the increased carbon dioxide concentrations in the atmosphere.

4-rising maximum temperatures.

rising minimum temperatures.

rising sea levels

your choice u can write this too (Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns)

5-It leads to a decrease of ozone, which protects the Earth from the Sun's heat. ... It includes greenhouse gases, which trap heat in the Earth's atmosphere again u can write this aswell(Global warming is primarily caused by emissions of too much carbon dioxide (CO2) and other heat-trapping gases into the atmosphere when we burn fossil fuels to generate electricity, drive our cars, and power our lives. These heat-trapping gases spread worldwide and remain in the atmosphere for decades to centuries)

6-CO2 levels are determined by the imbalance between carbon sequestration (burial in sediments, capture by plants), and carbon emissions (rock weathering and volcanic activity). Imbalances in this system created a downward trend in CO2 levels, leading to a glaciation period around 300 million years ago.

Neither the USGS nor any other scientists have ever predicted a major earthquake. USGS scientists can only calculate the probability that a significant earthquake will occur in a specific area within a certain number of years.

Answer:

The correct answer is: 0°C + 0°C = 32°F

Explanation:

We need to remember the conversion equation from Celsius to Fahrenheit:

[tex]y^{\circ}F=(x^{\circ}C * \frac{9}{5})+32[/tex]

In our case x = 0, then y will be:

[tex](0^{\circ}C * \frac{9}{5})+32=32[/tex]

[tex]y=32^{\circ}F[/tex]

Now 0°C + 0°C is just 0°C because if we add a body at a certain temperature to another body with the same temperature the total temperature will the same.

Then, knowing that 0°C = 32°F we can conclude that:

[tex]0^{\circ}C+0^{\circ}C=32^{\circ}F[/tex]

I hope it helps you!              

Answer:

when u find out pls lmk! i have the same question and I've been stuck for a while lol

Answers:

1) A process that occurs when an object or a particle moves, referred to as kinetic energy

2) A potential energy is a stored amount of energy that changes depending on the relative positions.

3) Potential Energy is the energy stored in an object due to its position. Kinetic Energy is the energy of motion in a moving object.

4)

  a) C and B

  b) A

  c) From B to A or from C to A

  d) From A to B or from A to C

[tex]\huge\mathfrak\green{answer}[/tex]

1) Kinetic energy of an object is the measure of the work an object can do by the virtue of its motion.

For Example : A river flowing at a certain speed comprises kinetic energy as water has certain velocity and mass.

2) Potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.

For Example : A child at the top of the slide

3) KINETIC ENERGY

POTENTIAL ENERGY

(make sure to draw a table and write them separately)

4)

a) C and B

b) A

c) B to A then C to A

d) A to B then A to C

Answer:

1/4

Explanation:

Mechanical Advantage = Load/Effort

Given

Effort applied = 24N

Load = 6N

Substitute

MA = 6/24

MA = 1/4

Hence the mechanical advantage is 1/4

Answer:

4

Explanation:

24n/6n=4

Answer:

21.5 miles

Explanation:

Distance = Speed * time

Distance  traveled in first 6 minutes = 52 * [tex]\frac{6}{60}[/tex]  = 5.2 miles

Distance  traveled in next 3  minutes = 46 *[tex]\frac{3}{60}[/tex] = 2.3 miles

Remaining minutes = 30 - 6 -3 = 21 minutes

Distance  traveled in 21 minutes = 40 * [tex]\frac{21}{60}[/tex] = 14 miles

Total distance traveled = 5.2 + 2.3 + 14 = 21.5 miles

Hello your question is incomplete below is the missing piece

What is the magnitude of the boat’s resultant velocity? Round your answer to the nearest whole number.

answer :  25.73 m/s

Explanation:

Given

V1 = 15 miles/hour =  6.71 m/s [ 45° EN ]

V2 = 18 m/s [ 5° NE ]

Calculate  the resultant velocity

Vr = 6.71 m/s[45°] + 18m/s[5°].

Vr = ( 6.71 *Cos45° + 6.71 *sin45°) + ( 18 *Cos5° + 18*sin5° )

Vr = ( 4.74  + 4.74 i  )+  ( 17.93 + 1.57i) = 22.67 + 12.18i.

Therefore the magnitude

= [tex]\sqrt{22.67^2 + 12.18^2}[/tex] = 25.73 m/s

Answer:

It would spin ifintely

Explanation:

Answer:

-1.69 m/s²

Explanation:

We are told the crane pulls up the mass with a force of 1150 N.

This means it is in an opposite direction to gravity and thus acceleration(a) is negative.

Now, the gravity is acting downwards, thus, total force is;

F = mg - ma

1150 = 100(9.81 - a)

Divide both sides by 100 to get;

11.5 = 9.81 - a

a = 9.81 - 11.5

a = -1.69 m/s²
