PLEASE HELP!!! GIVING BRAINLIEST!! ill also answer questions that you have posted if you answer this correctly!!!! (40pts)

Answers

Answer 1

Answer:

Newton's second law: F=ma.

Force = mass x acceleration

This basically means, that the more massive something is, and the faster it is going, the more force the object will have.

So, the factors that can be used to find acceleration are:

F=ma

a=F/m

So, we see that the correct answer is A, mass and force.

In air, a sound wave with a frequency of 200 Hz has a wavelength of about 1.5 meters. What is the wavelength of a wave if the frequency is increased to 600 Hz?

Answers

Answer:

see below

Explanation:

first of all, you find the speed of sound in air

which is

speed = frequency x wavelength

speed = 200 x 1.5

speed = 300 m/s

speed remains the same in the same medium

so you can use speed and frequency to find wavelength

speed = frequency x wavelength

300 = 600 x wavelength

wavelength = 0.5 m

How is the velocity of a wave affected by its frequency, wavelength, and period?

Answers

Answer:

I can only explain using the formula

Explanation:

v=f

[tex]v = f \times lamda[/tex]

v is velocity

f is frequency

lamda is wavelength ( I don't have the symbol)

therefore velocity is the product of frequency and wavelength

And since period is the inverse of frequency;

Period (T)=1/f

so we can have v=lamda/T

That's what I think

3. Suppose a free-fall ride at an amusement park starts at rest and is in free fall.

a. What is the velocity of the ride after 2.3 s?

b. How far do people on the ride fall during the 2.3-s time period?

Answers

Answer:

[tex]v = 22.54m/s[/tex] --- Velocity

[tex]h = 25.921m[/tex] --- Distance

Explanation:

Given

[tex]u = 0m/s[/tex] --- Initial velocity

Solving (a): Velocity after 2.3s

To do this, we use the first equation of motion

[tex]v = u + at[/tex]

Where

[tex]t = 2.3s[/tex]

[tex]a = g = 9.8m/s^2[/tex]

So, the equation becomes:

[tex]v = 0 + 9.8 * 2.3[/tex]

[tex]v = 0 + 22.54[/tex]

[tex]v = 22.54m/s[/tex]

Solving (b): Distance covered in 2.3s

We make use of:

[tex]h = ut + \frac{1}{2}gt^2[/tex]

This gives:

[tex]h = 0 * 2.3 + \frac{1}{2}*9.8 * 2.3^2[/tex]

[tex]h = \frac{1}{2}*9.8 * 5.29[/tex]

[tex]h = 25.921m[/tex]

Halogens are elements within group 17 on the periodic table. As argon is in group 18, which means it is a noble gas. Bromine, chorine, and flourine are all in group 17, making them halogens.

The work per unit charge required to move a charge between two points in an electric circuit defines electric
A) force
B) Power
C) field strength
D) potential difference

Answers

The work per unit charge required to move a charge between two points in an electric circuit electric potential difference. The right option is D) potential difference

What is electric potential difference?

Potential difference can be defined as the work done in moving a unit charge from one point to another in an electric field. The S.I unit of potential difference is volts (V).

From the question,

Force: is the product of mass and acceleration Power: This is the rate at which work is done.Field strength: This is the force per unit charge in a field.Potential difference: This is the work done in moving a unit charge from one point to another in a field.

Hence, from the above, the right option is D) Potential difference

An electron is located 4.22 mm away from an isolated proton. If the distance between the two particles is increased to 8.44 mm, what
happens to the electrical potential energy of the electron and why?
O A. The electrical potential energy will increase because work must be done to separate two particles that attract one another.
B. The electrical potential energy will remain the same because the electron and proton are both fundamental particles and their
charge cannot be changed.
O
C. The electrical potential energy will increase because larger energies are associated with greater distances.
O D. The electrical potential energy will decrease because no work is necessary to increase the distance between particles that

If the distance between the two particles is increased to 8.44 mm, the electrical potential energy will increase because work must be done to separate two particles that attract one another. Hence option(A) is correct.

What is potential energy?

Potential energy is the energy held by an object as a result of its position relative to other objects, internal stresses, electric charge, or other factors.

The gravitational potential energy of an object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field are all examples of common types of potential energy. The joule, denoted by the symbol J, is the unit of energy in the International System of Units (SI).

The positive and negative charges attract each other, so work must be done to separate two particles. Hence, the electrical potential energy will increase.
