A car with a mass 1235 kg accelerates at 3.82 m/s2. What is the total force exerted by
the car on the road (answer in N to two decimal places)?
Answers
Answer:
4717.70 NExplanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
mass = 1235 kg
acceleration = 3.82 m/s²
We have
force = 1235 × 3.82 = 4717.7
We have the final answer as
4717.70 NHope this helps you
Compare the amplitude of these waves.
Answers
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.
What is amplitude?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

A ceiling fan operates at three speeds, using 120 V of electricity from the wall. At low speeds, it uses 0.25 A. Calculate the resistance needed to generate that current. Then in 1-2 sentences, describe how the resistance would change at medium and high speeds if larger currents are needed at those speeds. Your answer should include the calculated resistance and a sentence describing your reasoning.
Answers
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.
See more about the application of Ohm's law at: https://brainly.com/question/10566593
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 :
R = 120 V ÷ 0.25 AR = 480ΩFor 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.

Answers
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.

One metre of a particular type of wire has a resistance of 30 Ω. What length of this wire will have a resistance of 6 Ω
Answers
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

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.
What is vitamin ?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.

What drawbacks might there be to this design?
