The acceleration is 3 [tex]m/s^2[/tex] when a block with a mass of 5 kg is pulled with a force of 15 n.

The block will experience a net external force of 15 N due to the frictionless surface it is kept in place on.

The block weighs 5 kg.

F = m × a

There is a net external force (F), mass (m), and acceleration acting on the object in this situation (a).

Using the appropriate values in place of F and m:

15 = 5 × a

15/5 = a

3=a

Taking 5 as a factor, we get 3 = a.

As a result, a 5-kilogram item is drawn over a friction less surface with an acceleration of 15 N is 3 m/s².

For such more question on acceleration.

The missing value is D. 98

The table provides information about the speed (m/s), frequency (Hz), and wavelength (m) of a sound wave generated by a musical note, in different mediums (air, glass, and brass). The frequency of the sound wave is constant across the three mediums, but the speed and wavelength will vary depending on the medium. Since we know the frequency and wavelength, we can use the formula:

Speed = Frequency x Wavelength

to find the missing value of the speed of the sound wave in brass.

4,700 = 55 x Wavelength

Wavelength = 4,700/55 = 85.818...

When the amplitude of a body undergoing simple harmonic motion is doubled then the maximum speed is doubled.

Equation of shm is

x(t) = Xo + Acos(wt + f)

Differentiate it with t

v(t) = wA * sin(wt + f)

Then max speed Vmax is wA

So by above relation if we double the amplitude then velocity will be doubled.

If the force acting on the oscillating body is always in the direction opposite to the displacement of the body from the equilibrium or the mean position and its magnitude is proportional to the magnitude of displacement, the body is said to be executing SHM.

If the displacement vs. time curve of the oscillating body is sinusoidal in nature, the body is said to be executing SHM. This is another definition of SHM.

If the potential energy of the oscillating body is proportional to the square of its displacement with reference to the mean position, the body is said to be executing SHM. This is yet another definition of SHM.

The correct option is C ; Water vapor , Water vapour is water that is gaseous rather than liquid. It can be generated by either evaporation or sublimation.

Water vapour, unlike clouds, fog, or mist, which are just suspended particles of liquid water in the air, cannot be seen since it is in gaseous form.

Water vapor has the same chemical formula as regular water - H2O - but the water molecules in vapor interact with each other less and are not as organized as they are in water and ice. Pressure, temperature, and relative humidity all influence whether water is liquid or gas.

When the outer wall moves at a speed of 3.0 m/s, and an 83-kg person feels a 545-N force pressing against his back then the radius of a chamber is 8.5 meters.

The radius of the chamber can be calculated using the equation

F = mv²/r, where F is the force felt by the person, m is the mass of the person, v is the velocity of the chamber and r is the radius of the chamber. In this case, F is 545 N, m is 83 kg, and v is 3.0 m/s.

Plugging in these values, we get

r= mv²/F

r= 83×3²/545

r = 8.5 m.

Answer:

Speed is the measure of how fast something moves

Explanation:

The gravitational pull on the spacecraft is discovered to be inversely proportional to the distance from the Earth.

If the gap were cut in half, the gravitational attraction would be more powerful. According to Coulomb's rule, the gravitational force between any two things in the universe is inversely proportional to the sum of their respective masses.

The gravitational force between two things in the cosmos is calculated as being inversely proportional to their distance from one another. Gravity is the force that holds two bodies together, body present or not.

A force that is directly inversely correlated to the square of the distance between bodies and directly inversely correlated to their product draws every body in the universe toward every other body.

Dynamic flexibility tests are not used as often as static flexibility tests because dynamic flexibility tests involve movement, while static flexibility tests are stationary.

Dynamic flexibility tests are more difficult to perform and require more coordination, and they can be less reliable than static flexibility tests. Additionally, dynamic flexibility tests require more time and equipment to administer, making them less practical for most fitness assessment settings.

Also, dynamic flexibility tests are more specific and measure the ability to perform a specific movement, rather than measuring the general range of motion of a joint. This makes them more suitable for testing athletes and those who need to measure their ability to perform specific movements.

Seeing the fur rubbed with the rod attracts neutral paper, this happens because the friction of the rod with the rubbed can produce a static electric force. It is this static electric force that causes the pieces of paper to be attracted and rod up.

If the rod or ruler has been rubbed into the hair, then brought closer to the paper, then the paper will lift and stick. Indeed, this can happen due to the presence of an electric charge. When you rub a plastic ruler over your hair, it becomes electrically charged, causing the paper to pull and stick.

The electric charge consists of two types of charge, namely negative charge, and positive charge. However, some objects have an equal amount of negative charge and positive charge. Objects that have the same amount of positive and negative charges are called neutral objects. Initially, a plastic ruler is also an electrically neutral object.

The ring accelerates in the direction of the net unbalanced force. Thus option C is the correct answer.

According to Newton's second law of motion, the net force acting on an object is equal to the mass of the object multiplied by its acceleration. If the forces exerted by the two students in the tug-of-war are unbalanced, there will be a net force acting on the steel ring.

The direction of this net force will be in the direction of the stronger force. As a result, the ring will accelerate in the direction of the net unbalanced force. This means that the ring will begin to move, and its velocity will change as long as the net force is applied.

Since the steel ring is accelerating, it can no longer be at rest, and it will not move at a constant velocity. The ring will move in the direction of the stronger force until the forces exerted by the students are balanced again.
