Explanation:

It has the greatest percentage out of the pie chart.

Answer:

Explanation:

it will result in rise in frequency of the wave ...

so speed of the wave will increase...

If Farah increases the temperature in the room during the experiment, C. the speed of the wave will increase.

A longitudinal wave is the opposite of a transverse wave and it can be defined as a type of wave that usually travel in the same direction of its oscillation.

Generally, there is a direct (linear) relationship between the speed of the wave and temperature.

This ultimately implies that, if Farah increases the temperature in the room during the experiment, the speed of the wave will increase due to an increase in its frequency.

Answer: Average velocity = u+v/2

Explanation: The definition of velocity is displacement over time taken. That is,

Velocity = displacement/ time taken

But we have initial velocity U and final velocity V. When we are talking about average, we are talking about the mean value of the given parameters.

Therefore, average velocity will be addition of initial velocity and final velocity divided by 2. That is,

Average velocity = (U + V)/2

Answer:

0.0045 s

Explanation:

Period = 1 / frequency

T = 1 / (220 Hz)

T = 0.0045 s

Because the moon has much less mass than the Earth has.  This makes the gravitational forces between the moon and any object much less than the forces between the Earth and the same object, when the object is the same distance from the center of the moon or the Earth.

To talk about an actual number, we usually talk about being on the surface of the Earth or the moon:

A person or object on the surface of the moon weighs about 17% as much as he/it weighs on the surface of Earth. That's about one-sixth as much.  So naturally, it's easier to lift something on the moon than it is to lift the same thing on Earth, because when it's on Earth, it's about six times as heavy.

Answer:

A long handle

Explanation:

A spanner is basically a wrench, you would also want to use a long handled wrench in order to have more mechanical advantage and be able to apply more torque. This can be proven as well using a simple physics formula:

[tex]t = fd[/tex]

where the variables are:

t = torque

f = applied force

d = perpendicular distance from fulcrum to where the force is applied

It is clear that keeping the applied force constant, if you enlarge the perpendicular distance, d, you will be able to apply more torque and therefore have an easier time releasing this nut.

Answer:

50w

Explanation:

Power is equal to Energy divided by Time

∆E/t

Answer:

50 W

Explanation:

Power can be found using the following formula.

p=w/t

where w is work and t is time.

400 Joules of work is done on the object in 8 seconds. Therefore,

w= 400 J

t= 8 s

Substitute these values into the formula.

p=400 J/ 8 s

Divide 400 by 8

p=50 J/s

Add appropriate units. In this case, power uses Watts, or W. (1 Joule per second, or J/s is equal to 1 Watt, or W)

p= 50 W

The object experiences 50 Watts of power

Answer:

So if its regular, you would always tighten it. Here's the reasoning:

"When you lower the pitch by releasing tension, there might be slack in the gears in the tuning machines, which might make the string go below the intended pitch. By going further down and approaching the target note from below, there will be force applied to the gears and when you've reached the correct pitch the gears have less potential to move. So your teacher is correct."

Answer:

They would repel because they are opposites

Explanation:

The two point charges will repel each other with a force of 9×10⁹N because they both have the same nature of the charge.

Given two point charges with a charge of +1.00 C. Separated by a distance of 1 m.

So, q₁ = q₂ = 1C and distance r = 1m

Since the charges are alike, that is both of them are positive charges, they will repel each other with an electrostatic force given by:

F = kq₁q₂/r²

where k is Coulomb's constant.

F = 9×10⁹×1²/1²

F = 9×10⁹N

Mass, m = 2650 kg

Explanation:

We have,

Kinetic energy of  Mr. Thomson’s prius is 641300 J

He is moving with a velocity of 22 m/s

It is required to find the mass of Mr. Thomson’s prius.

Kinetic energy,

[tex]K=\dfrac{1}{2}mv^2[/tex]

Plugging all the values, we get :

[tex]m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 641300}{(22)^2}\\\\m=2650\ kg[/tex]

So, the mass of Mr. Thomson’s prius is 2650 kg.

Frequency is the amount of times the particle moves back and forth per second, more or less. The more energy, the higher the frequency. At the same time, the more energy means you'll have a shorter wavelength (aka period). Color only applies to the visible spectrum.

Answer:

Explanation: The greater the number of waves appear the greater the energy. The smaller the number of waves appear the lower the energy.

Frequency is the number of times waves appear.

To find out:

What is the resultant force?

Solution:

Resultant Force = Forward force + Reserve force

= 100 N + ( - 25 N )

= 75 N

Answer:

75 N

Explanation:

The resultant force can be found using the following formula:

F=forward force + reverse force.

The forward force is 100 N.

The reverse force is 25 N. Since it is a reverse force, it is actually equal to -25 N.

forward force=100 N

reverse force= -25 N

Substitute these values into the formula

F=100 N + -25 N

Add 100 and -25

F= 75 N

The resultant force is 75 Newtons.
