This could actually help. By doing this if the house is strong enough the water would go straight through the house just destroying furniture and anything else inside your house. This could also still hurt you the water could miss and still destroy your house so having this would have been a waste of money.

Answer:

It would help, because it would destroy everything inside the house, but not the house itself. Although whatever got ruined in there would have to be payed for, or the wave can miss.

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.

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.

Specialized businesses that help coordinate dealings between other companies are called Agencies. Thus, the correct option is A.

Specialized businesses are the businesses which have their own marketing opportunities and challenges as well. This is also known as niche marketing, and the focus here is on the connection of business with a specific, targeted audience and also communicating the features and benefits of the products or services of their businesses.

An agency generally refers to a relationship that is comprising of two parties, where one party is called the agent, whereas the other party represents the principal party. An agent is usually hired by the principal party to perform an act or service on his own behalf.

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.

we struggle to maintain a fitness regime

Answer:

0.20 m.

Explanation:

Given: R = 30 Ω and L = 1 m

Resistance of 1m wire is R = V/I = 30Ω/0.1A

6Ω resistor will have the same voltage drop across it as 1m wire, so we require I to be 6A. Therefore, the required length of wire  is:

L = (6A)/(30Ω) = 0.2m

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

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. A is correct.

The range of 95-99% represents normal, healthy oxygen saturation levels. And can be simply measured with a fingertip pulse oximeter, a cheap, basic equipment. Your blood oxygen saturation is most likely within the typical range for active, healthy athletes (like you!).

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.

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

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.
