Explanation:

accelration formula : final velocty - starting velocity divided by time

Answer:

The resistance is 0.617Ω.

Explanation:

Given that the formulas are V = I × R and P = I × V so when you substitute the V formula into P formula, you will get P = I² × R. Using this formula, you can find the resistance :

P = I² × R

50 = 9² × R

50 = 81 R

50 ÷ 81 = R

R = 0.617Ω (3sf)

Answer:

h = 3.3 m (Look at the explanation below, please)

Explanation:

This question has to do with kinetic and potential energy. At the beginning (time of launch), there is no potential energy- we assume it starts from the ground. There, is, however, kinetic energy

Kinetic energy = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]

Plug in the numbers = [tex]\frac{1}{2}[/tex](4.0)([tex]8^{2}[/tex])

Solve = 2(64) = 128 J

Now, since we know that the mechanical energy of a system always remains constant in the absence of outside forces (there is no outside force here), we can deduce that the kinetic energy at the bottom is equal to the potential energy at the top. Look at the diagram I have attached.

Potential energy = mgh = (4.0)(9.8)(h) = 39.2(h)

Kinetic energy = Potential Energy

128 J = 39.2h

h = 3.26 m

h= 3.3 m (because of significant figures)

Answer:

441J

Explanation:

Given parameters:

Mass of book  = 5kg

Height  = 9m

Unknown:

Gravitational potential energy  = ?

Solution:

The gravitational potential energy of a body is the energy due to the position of the body.

 It is given as:

   Gravitational potential energy = mass x acceleration due to gravity x height

Gravitational potential energy  = 5 x 9.8 x 9  = 441J

Answer:

Please find the calculated values entered into the following table;

[tex]\left\begin{array}{ccccc}Object & Mass \ (kg)& Weight \ (N) & Height \ (m)&G.P.E.\\A&5&50&2&100\\B&2&20&6&120\\C&8&80&5&400\\D&20&200&0.6&120\\E&5,000&50,000&2&100,000\\F&0.2&2&10&20\\G&67&670&44&29,480\end{array}[/tex]

Explanation:

The given parameters are;

The acceleration due to gravity, g ≈ 10 N/kg

The Gravitational Potential Energy, G.P.E. = m × g × h

The weight of the object, W = m × g

∴ G.P.E. = W × h

The table is filled using the above formula for calculations as follows;

For object A, we have;

Weight = 5 kg × 10 N/kg = 50 N

G.P.E. = 50 N × 2 m = 100 J

For object B, we have;

Weight = 2 kg × 10 N/kg = 20 N

G.P.E. = 20 N × 6 m = 120 J

For object C, we have;

Weight = 8 kg × 10 N/kg = 80N

G.P.E. = 80 N × 5 m = 400 J

For object D, we have;

Weight = 20 kg × 10 N/kg = 200 N

G.P.E. = 200 N × 0.6 m = 120 J

For object E, we have;

Weight = 5,000 kg × 10 N/kg = 50,000 N

G.P.E. = 50,000N × 2 m = 100,000 J

For object F, we have;

Weight = 0.2 kg × 10 N/kg = 2 N

G.P.E. = 2 N × 10 m = 20 J

For object G, we have;

Weight = 67 kg × 10 N/kg = 670 N

G.P.E. = 670 N × 44 m = 29,480 J

Therefore, we have the table filled as follows;

[tex]\left\begin{array}{ccccc}Object & Mass \ (kg)& Weight \ (N) & Height \ (m)&G.P.E.\\A&5&50&2&100\\B&2&20&6&120\\C&8&80&5&400\\D&20&200&0.6&120\\E&5,000&50,000&2&100,000\\F&0.2&2&10&20\\G&67&670&44&29,480\end{array}[/tex]

Answer:

Gravitational potential energy is the maximum at point C and lowest at point A

Explanation:

The image for the question is provide in the attached file

The energy of pendulum is governed by mechanical energy. Mechanical energy is the sum of potential energy and kinetic energy

Potential energy increases with increasing height. Thus, when the pendulum bob is at maximum height, then its potential energy is also the highest.

Thus, At point C, the gravitational potential energy is the highest

At point A, the  gravitational potential energy  is substantial but lower than that of gravitational potential energy at point C

AT point A, gravitational energy is the lowest

Answer:

A

Explanation:

The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound.

Answer:

W = 15,000 Joule

Explanation:

Mechanical Work

Mechanical work is the amount of energy transferred by a force. It's a scalar quantity, with SI units of joules.

If both the force and displacement are parallel, then we can use the scalar formula:

W=F.s

Where

F =Magnitude of the force

s = magnitude of the displacement

The tornado moved a trailer with a force of F=600 N for a distance of s=25 m. The work done was:

W = 600 N * 25 m

W = 15,000 Joule

Answer:

The answer is long- term goal

Explanation:

Answer:

The internal energy of a substance is equal to the total amount of potential energy and kinetic energy of ALL the particles in the substance.

For example, when the temperature increases (more temperature means more energy), the kinetic energy of the particles in the substance increases.

And when we reach a point near a change of phase (like near fusion point) there is energy used to break the bonds between the particles, then we have an increase in potential energy.

Then we could write the internal energy as:

U = ∑(KEₙ) + ∑(PEₙ)

Where ∑(KEₙ) and ∑(PEₙ) are the sums of the kinetic energy and potential energy of all the particles in the substance.

The equation that best summarizes the internal energy (U) of a substance that has both kinetic and potential energy is U = ∑(KEₙ) + ∑(PEₙ).

Therefore, equation that best summarizes the internal energy (U) of a substance that has both kinetic and potential energy is U = ∑(KEₙ) + ∑(PEₙ).

An object with greater charge will exert a greater force on an object than an object with smaller charge would. However, if you consider two charges that exert a force on each other, regardless of the magnitude of charge, both charges will exert an equal force on each other because of Newton's third law.

Answer:

4.5m

Explanation:

Distance is the total length of path traveled or covered by a body.

So distance is a scalar quantity, it only has magnitude but no direction.

Therefore:

Total distance = 3 m + [tex]\frac{1}{2}[/tex](3)

So;

        3 + 1.5  = 4.5m

Total distance covered 4.5m by the body.

Answer:

The air speeds up, and as it speeds up, its pressure—the force of the air pressing against the side of the object—goes down. ... This means that if the area in which the air is moving narrows or widens, then the air has to speed up or slow down to maintain a constant amount of air moving through the area.

bc we play when we are bored and some people use it as a tradition to play on thanksgiving

Answer:

Explanation:

Take for example you place two eggs in the water. One starts to sink and one remains floating. They have the same volume but the one that sinks is cracked just a little, which as soon as it hits the water, water starts to go in the egg. Then that changes the volume of the egg. (I've done this expirement before) It can also be the way you place the object in the water, or one object has been in the water longer. The buoyancy can be the way they are positioned/placed in the water. One may be more absorbant to the water as well.

I hope you understand what I am trying to say.

Answer:   0.0035

============================================

Explanation:

The exponent is -3, so we move the decimal point 3 spots to the left to go from 3.5 to 0.0035

If the exponent was positive, then we would move the decimal point to the right that amount of spaces.
