What are two ways you can increase power by climbing the stairs?

Answers

Answer 1

Answer:

change the

timedistance force.

Explanation:

P = W/time

W = F*d

You have control over how fast you go up the stairs.

You also have control over how far up the stairs you go.

Therefore the answer is

timedistance

If you don't like distance as an answer, you can carry something up the stairs -- anything that increases F will do.

Australian Tiger beetles can travel 2.5 m/s. How long would it take a tiger beetle to run the length of a standard football field (109.7 m)?

Answers

Answer:

Time = 43.88 seconds

Explanation:

Given the following data;

Speed = 2.5 m/s

Distance = 109.7 m

To find the time it would take to run the length of a standard football field, we would use the following formula;

[tex]Speed = \frac{distance}{time}[/tex]

Making time the subject of formula, we have;

[tex]Time = \frac{distance}{speed}[/tex]

Substituting into the formula, we have;

[tex]Time = \frac{109.7}{2.5}[/tex]

Time = 43.88 seconds

Therefore, it would take a tiger beetle 43.88 seconds to run the length of a standard football.

A hydrogen atom and a carbon atom move at the same speed. Which has the greater kinetic energy?

Answers

Answer:

The carbon atom has greater kinetic energy than a hydrogen atom.

Hope this helps! :)

Carbon atom has the greater kinetic energy.

What is meant by kinetic energy ?

Kinetic energy is defined as the energy attained by a body by virtue of its motion.

Here,

The speed of the hydrogen atom and carbon atom are the same.

Kinetic energy of hydrogen atom, KEн = 1/2 m(н) v(н)²

Kinetic energy of carbon atom, KEс = 1/2 m(с) v(с)²

where m and v are mass and speed respectively.

Taking the ratio,

KEн/KEс = m(н)/m(с)

KEн/KEс = 2/12

KEн/KEс = 1/6

KEс = 6KEн

Therefore the kinetic energy of carbon atom is 6 times the kinetic energy of hydrogen atom.

Hence,

Carbon atom has the greater kinetic energy.

A factory has 1200 workers of which 720 are male and the rast are female what percent of workers are female​

Answers

Answer:

Percent of Female Workers = 40%

Explanation:

The percentage of the female workers in the given group of workers can be easily found by the following formula:

[tex]Percent\ of\ Female\ Workers = \frac{No.\ of\ Female\ Workers}{Total\ No.\ of\ Workers}\ x\ 100\%[/tex]

where,

Total No. of Workers = 1200

No. of Female Workers = Total Workers - No. of Male Workers

No. of Female Workers = 1200 - 720 = 480

Therefore,

[tex]Percent\ of\ Female\ Workers = \frac{480}{1200}\ x\ 100\%[/tex]

Percent of Female Workers = 40%

B)

C)

Answers

Answer:

55 degrees

Explanation:

A ray of light strikes a plane mirror at an angle of incidence. The angle between the incident ray and the reflected ray is 70°. The correct option is A.

What is law of reflection?

The law states that angle of incidence of the incident ray is equal to the angle of reflection through a plane surface.

Here, angle of incidence of light on a plane mirror is 35°, then the angle of reflection will also be 35°.

i = r = 35°

Then the angle between the incident ray and the reflected ray will be

i +r = 35 + 35 =70°

Thus, the correct option is A.

Qs 5 pleaseeee help!!!

Answers

Answer:

Ok, first is important that you understand how the heat radiation works.

All the objects that have some heat energy in them, radiate some of that energy in the form of electromagnetic waves.

Particularly, the Sun radiates a lot of energy (at the point that if you step under the sunlight, you can feel on your skin the heat that comes from the sun, this is due to radiation).

Now, suppose that you have a thin coat of water over you, then the material that gets impacted by that radiation will be the water and not you, and then the energy is dissipated (some of the energy goes to your body and some go to the air)

This is one way in which spraying water over themselves helps the elephants to keep them cool.

Another way in which heat can be transferred is by conduction.

When you have a hot object and a cool object, and you put them together (so the objects touch each other), the heat will flow from the hotter object to the cooler object until both objects have the same temperature.

Then if the elephant body temperature is larger than the temperature of the water that the elephant sprays over his body, when the water touches the body some of the heat in the elephant body will be transferred to the coat of water, and in this way, the temperature of the elephant's body decreases.

These are the two ways we wanted to find.

A person pushes a 125 kg object initially at rest on a frictionless surface. The object ends up with a final velocity of 1.40 m/s. What is the total
translational kinetic energy of the object?

Answers

Answer:

a person pushes a 125 kg

Explanation:

The total translational kinetic energy of the object is 122.5 J.

What is meant by kinetic energy ?

Kinetic energy is defined as the energy possessed by a body by virtue of its motion.

Here,

Mass of the object, m = 125 kg

The final velocity of the object, v = 1.4 m/s

It is given that the object was initially at rest on a frictionless surface. When the object was pushed by the person, it gained some amount of kinetic energy and ended up with a final velocity of 1.4 m/s.

So, the expression for total translational kinetic energy of the object is given by,

KE = KEf + KEi

KE = 1/2m(v² + u²)

Since, the object was initially at rest, the initial velocity,

u = 0

Therefore, the kinetic energy of the object,

KE = 1/2 mv²

KE = 1/2 x 125 x (1.4)²

KE = 122.5 J

Hence,

The total translational kinetic energy of the object is 122.5 J.

An electric current will always follow the path of least resistance. So, the right option is a.

In inverse relation to the resistance of the pathways, electric current follows every available paths.

The voltage and resistance of the path in the electric circuit affect the amount of electric current that flows through the circuit.

The quantity of electric current flowing through the circuit is inversely proportional to the resistance in the circuit.

Assuming a fixed voltage, the current increases with decreasing resistance. The current decreases in accordance to the level of increasing resistance.
