HELP PLEASE!!!a= ?v=r=

Answers

Answer 1

Answer:

[tex]a=\frac{v^2}{r}[/tex]

[tex]v=\sqrt{a*r}[/tex]

[tex]r=\frac{v^2}{a}[/tex]

Explanation:

This is the formula for centripetal acceleration in terms of the tangential velocity (v) and the radius of the circular motion (r).  The expression for the acceleration is already given, so simply type it as shown:

[tex]a=\frac{v^2}{r}[/tex]

For the velocity (v) multiply by "r" both sides and then use the square root to solve for v:

[tex]a*r=v^2\\v=\sqrt{a*r}[/tex]

For the radius multiply both sides by r and then divide both sides by the acceleration (a) in order to isolate r completely:

[tex]a*r=v^2\\r=\frac{v^2}{a}[/tex]

Answers

Answer:

C. amount of charge on the source charge.

Explanation:

Electric field lines can be defined as a graphical representation of the vector field or electric field.

Basically, it was first introduced by Michael Faraday and it is typically a curve drawn to the tangent of a point is in the direction of the net field acting on each point.

The number, or density, of field lines on a source charge indicate the amount of charge on the source charge. Therefore, the density of field lines on a source charge is directly proportional to quantity of charge on the source.

The SI unit for energy is Newton true or false

Answers

Explanation:

false....it is joules

..........

The answer is false

The SI unit for energy is joules and not Newton. Energy can be described as the capability of an individual to perform work. Every day all living things carry out one form of work or the other. These might include walking, running, cooking, singing, driving etc. All these activities require energy, some require a whole lot of energy.

This is why the importance of energy for our day to day activities cannot be over emphasized.

Hence the SI UNIT for energy is joules.

How much energy is transferred when the potential difference is 12V and the charge is 7.5C?

Answers

So you do 12 multiplied by 7.5 which is 90, so your answer is 90J :)

The energy is transferred when the potential difference is 12 volts and the charge is 7.5 C is 90 Joules.

What is energy?

In physics, energy is the capacity to carry out work. It might be potential, kinetic, thermal, electrical, chemical, radioactive, etc., among other types. Heat and work are other examples of energy being transferred from one body to another. Once it has been transmitted, energy is always allotted according to its nature. As a result, heat transmission could result in thermal energy while effort could provide mechanical energy.

Given the information in the question:

The potential difference, V = 12 Volts,

The charge, q = 7.5 C,

Calculate the energy, E by the formula given below,

E = [tex]VQ[/tex]

Substitute the values of charge and potential difference,

E = [tex]12*7.5[/tex]

E = [tex]90 Joules[/tex]

Therefore, the energy is transferred when the potential difference is 12 volts and the charge is 7.5 C is 90 Joules.

Lightning flashes and you hear a thunder clap for seconds later. the velocity of sound is 340 m/s. how far away did lightning strike ?​

Answers

Answer:

For metric-system conversions, follow this method: Sound travels at about 340 m/s, so multiply the number of seconds you counted by 340, and you'll know how many meters away lightning struck. A three-second count, then, would place the lightning strike about 1,020 m away, or roughly 1 km.

Explanation:

hope it hep and if it doesnt sorry

The distance struck by the lighting flashes is 680 m.

The given parameters;

time taken to hear the thunder clap, t = 4 svelocity of sound, v = 340 m/s

The distance struck by the lighting is calculated by applying the principle of echo as follows;

[tex]v = \frac{2d}{t} \\\\2d = vt\\\\d = \frac{vt}{2} \\\\d = \frac{340 \times 4}{2} \\\\d = 680 \ m[/tex]

Thus, the distance struck by the lighting flashes is 680 m.

Different isotopes of an element can exist. For example, Carbon can have a mass number of 12 or a mass number of 14. Carbon always has an atomic number of 6.

Describe the difference between these two isotopes of Carbon.

In your answer, compare the number of protons, neutrons and electrons.

Answers

Answer:

Carbon 14 has 2 more neutrons than Carbon 12

same number of protons and electrons if they are both neutral atoms (that is the +  or - aspect)

Explanation:

Answer:

The difference is the number of neutrons they have.

Explanation:

The atomic number is the number of protons. The number of protons is what differentiates elements. The isotope number is the total weight of the atom, that is the protons plus the neutrons. Therefore the number of neutrons is equal to the atomic mass minus the atomic number. Electrons are generally equal to the number of protons, to balance the charge of the atom.

In short: the difference between the two isotopes is that one has more neutrons.
