Answer:

Explanation:

Work is the dot product of force and distance

[tex]W = F*d=Fd*\cos(theta)[/tex]

The only force acting on this box is the force of gravity (weight) which is mass*gravity

F = (1.6)(9.8) = 15.68N

The angle is the angle between the force and distance. In this case it is zero, therefore cos(Ф) = 1

[tex]W=15.68*2.4=37.6J[/tex]

Answer:

The Anti Reflective Coating on a solar cells helps to increase the amount of light absorbed into the cell. This anti reflective coating is very much needed as the reflection of a bare silicon solar cells is over 30%. For the thin AR Coating, silicon nitride or titanium oxide is used.

Answer:

29.4 m/s.

Explanation:

v=gt=9.8⋅3=29.4

I believe this is correct... If not, close.

Answer:

Workdone = 500Nm

Explanation:

Given the following data;

Force = 100N

Distance = 5m

To find the workdone;

Workdone is given by the formula;

[tex] Workdone = force * distance[/tex]

Substituting into the equation, we have

[tex] Workdone = 100 * 5 [/tex]

Workdone = 500Nm

Answer:

Solar radiation is radiant energy emitted by the sun, particularly electromagnetic energy.

Answer:

the earth because us humans all live there and do many things like excercise jobs cleaning and other things

Answer:

The manner in which the Earth's movement affect how the Sun is seen is;

The Sun is stationary, but Earth's rotation makes it appear to move East to West across the sky

Explanation:

The Earth's movement affect the way the Sun is seen

The Sun appears to rise in the Eastern part of the sky and continues in motion till the it sets at the Western part of the sky

However, the Sun does not actually move relative to the Earth as seen in the sky. The observed motion of the Sun is due to the counterclockwise  rotation of the Earth about its axis

Therefore, the Earth's movement affect the way the Sun is seen by making the Sun appear to move across the sky from East to West

Answer:

The sun stays still but the rotation of the earth makes it look like it goes east to west.

Explanation:

The true statement regarding the transverse waves should be option D. the direction at which the energy and the matter should be travel in the perpendicular direction.

It is the waves where the motion in which all the points should be on the wave oscillate along the paths at the right angles with respect to the wave of the direction. The example of this kind of waves should be electromagnetic, etc. In this, the directions where the energy and the travel of matter should be perpendicular to each other

Hence, the correct option is d.

Answer:

newton's first law of motion

Explanation:

this is because newton's first law of motion states that every object will continue in its state of rest or uniform motion in a straight line unless a resultant force acts on it so...

isn't this similar to the law of inertia?

yes it is

hope this helps

Answer: True

Explanation:

Distance is a scalar, which means it has no direction. It is the sum of the entire path traveled.

Displacement is a vector, which means it does have direction. It is the shortest path from the start to the end. It is defined as [tex]x_f-x_i[/tex].

There is some sort of "rollers" on the trail part that is used to make the roller coaster move when it is going up. Then because of that, the speed gets quicker when it drops down, so then it could move for a longer time until it reaches the next arch.

Answer:

B.

Explanation:

Given that a student runs up a flight of stairs which info is not needed to calculate the rate of the student is doing work against gravity A the height of the flight of stairs B the length of flight of stairs C the time taken to run up the stairs D the weight of the student

The rate of doing work is known as power.

Power = work done/time

Work done = energy = mgh

Since energy = mgh

Where mg = weight

And h = height

Time = time taken to run up the stairs.

Time, weight mg and height h will be needed while the Length of the flight is therefore not needed.

The correct answer is B.

Answer:

It is recommended that you exercise within 55 to 85 percent of your maximum heart rate for at least 20 to 30 minutes to get the best results from aerobic exercise. The MHR (roughly calculated as 220 minus your age) is the upper limit of what your cardiovascular system can handle during physical activity.
