Answer:

27.82998 km/min

Explanation:

To convert m/sec into km/hr, multiply the number by 18 and then divide it by 5.

Ohm's law describes the relations among voltage, current and resistance. So that:

i. The resistance needed to generate the given current is 480 Ohm's.

ii. At medium speed, the resistance decreases while the current increases.

iii. The high speed requires large current but least resistance.

Ohm's law states that:  V = IR

where V is the voltage, I is the current and R is the resistance.

Thus from the given question, V = 120 V, and A = 0.25, so that:

R = [tex]\frac{V}{I}[/tex]

  = [tex]\frac{120}{0.25}[/tex]

R = 480 Ohm's

Therefore, the resistance required to generate a current of 0.25 A at low speed is 480 Ohm's.

Ohm's law explains that the voltage is proportional to current so that to generate greater amount of current, low resistance is required. Thus, at the medium speed, more current would be required so that the value of resistance to produce the current would be lesser than that at the low speed.

At higher speed, the value of resistance would reduce far below that attained in medium speed, so that more current would be produced. Thus the high speed requires large current but low resistance.

The answer is 480Ω.

According to Ohm's Law, the required equation to find resistance is :

[tex]\boxed {R = \frac{V}{I}}[/tex]

Then, by direct substitution, we get :

For medium and higher speeds, the resistance would have to decrease in order to allow for more current to reach the fan. For it to operate at the necessary speeds, the resistance would have to be less than 480Ω.

There are a few benefits to taking vitamins, but they’re not worth the cost. This is the BEST response to this statement. Hence option A is correct.

A vitamin is an organic molecule (or a group of closely related chemicals known as vitamers) that is required by an organism in trace amounts for appropriate metabolic activity. Essential nutrients cannot be synthesised in significant amounts by the organism and must therefore be received from the food. Vitamin C, for example, may be synthesised by certain species but not by others; it is not a vitamin in the first case but is in the second. Most vitamins are composed of groups of linked molecules known as vitamers rather than single molecules. Vitamin E, for example, has eight vitamers: four tocopherols and four tocotrienols.

Hence option A is correct.

It takes 29.5 days for a new moon to occur approximately after a full moon.

This question involves the concepts of Newton's Second Law of Motion, Force, and acceleration.

The engineer must design an engine that can produce a force of "3100 N".

According to Newton's Second Law of Motion:

[tex]F = ma[/tex]

where,

F = Force of engine = ?

m = mass carried by engine = mass of cart + mass of person = 75 kg + 80 kg

m = 155 kg

a = acclereration of the cart = 20 m/s²

Therefore,

[tex]F = (155\ kg)(20\ m/s^2)[/tex]

F = 3100 N = 3.1 KN

William Herschel thought he had found a comet when he spotted the green disk of Uranus.

Uranus is the seventh planet located far away from the Sun. It is a gaseous planet which was discovered in 1781, mistaken by a comet but after two years it was accepted as a planet. After decades of observations and only one close visit by a spacecraft, which shows us that Uranus has unique atmosphere.

Atmosphere of Uranus is mostly made up of hydrogen and helium as well as a small amount of methane and traces of water and ammonia. The presence of methane gas gives blue colour to Uranus so we can conclude that Uranus is the planet which was thought first a comet by William Herschel.

50 x 0.50

The force required to accelerate a 0.50 kg ball at 50 m/s² is 25 N.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Force = mass*acceleration

Force = 50 x 0.50

Force =  25 N

The force required to accelerate a 0.50 kg ball at 50 m/s² is 25 N.

Answer:

Explanation:

Answer:

Gravity

Explanation:

The larger the object, the bigger and more powerful its gravitational field is. That is how tides and waves are made. The moon is a bit more than 1/4 of earths size. This may seem small, but its actually VERY big considering the fact that the earth is 7,917.5 miles big in diameter. AT night, the tide is more major and waves are larger because the moon is directly above the ocean, using its gravitational force to pull at the waters. Same with any other object. If you fly over the Mir Mine, an abandoned diamoned mine in russia, that you woud be sucked into the 1,722 feet pit. If you try to jump off of a falling building, instead of leaping away, you would be pulled down with the building.

Answer:

Explanation:

The answer to your question would be number 2 amplitude and frequency are the same so the higher the frequency the higher the amplitude. As you can see in the picture wave E has the  highest frequency. which means since A has the lowest  frequency and E has the highest frequency answer 2 would be correct the amplitude increases from A to E.

Amplitude of a wave is the strength of the wave. It is measured from the central line of the wave to the top of the crest or bottom of the trough. Thus, higher amplitude waves will gives sharp crests and troughs. Here amplitude is increasing from A to E.

Amplitude is a parameter measuring the strength of a wave. It is the maximum displacement moved by the wave from its equilibrium position. The vibrational path will be twice that of the amplitude of the wave.

As the amplitude of the wave increases its intensity increases. Both are in direct proportion with the frequency and energy of a wave. For instance the amplification of sound waves increases the intensity of waves that we hear.

The distance between two consecutive crests or troughs is the wavelength of the wave not amplitude. Amplitude is measured from the axis line to the top of the crest thus, from exact middle of the wave crest to the top or to the bottom of trough.

Thus, higher amplitude waves will gives sharp crests and troughs. Here amplitude is increasing from A to E

Every physical activity requires a specific amount of oxygen for the human organs (heart, lungs, and muscle). Athletes must breathe efficiently to perform at their best, since a high oxygen level reduces fatigue and dizziness and promotes peak performance. Thus option 1. A, 2. D, 3. B, 4. A, 5.

Numerous websites that promote the purported advantages of breathed oxygen can be found by searching for “supplemental oxygen and athletes.” Almost all of them receive funding from businesses that sell oxygen.

Hi there!

(A)

We can solve for acceleration using the following equation:

Δd = vit + 1/2at²

The shuttle lifts-off from rest, so:

Δd = 1/2at²

Rearrange to solve for 'd':

2Δd/t² = a

2(350)/(3.5²) = 57.14 m/s²

(B)

Now, we can use this equation to solve for final velocity:

vf = vi + at

vf = at

vf = 57.14 × 3.5 = 200 m/s

(C)

Now, we can use the following equation to solve for displacement:

Δd = vt

Δd/v = t

350/200 = 1.75 sec
