Rearrange this equation so it equals d<br> v=dt
irina1246 [14]

Answer:

Below

Explanation:

To solve for d rearrange the formula v = (d)(t) to:

  d = v / t

I'm not to sure if you are using different variables but usually in physics the formula for velocity is v = d / t not v = dt

If you wanted to solve for displacement you would do:

  d = (v)(t)

Hope this helps!

Coulomb's Law: Two identical small charged spheres are a certain distance apart, and each one initially experiences an electrost
Ahat [919]

Answer:

The magnitude of electrostatic force on each charge is quarter of the magnitude of initial electrostatic force. ( ¹/₄ F)

Explanation:

The electrostatic force between two charges is given by Coulomb's law;

F = \frac{kQ_1Q_2}{r^2}

where;

Q₁ and Q₂ are the magnitude of the charges

r is the distance between the charges

k is Coulomb's constant

Since the charges are identical;

Q₁ = Q

Q₂ = Q

the electrostatic force experienced by each charge is given by;

F =  \frac{kQ^2}{r^2}

When each of the spheres has lost half of its initial charge;

Q₁ = Q/2

Q₂ = Q/2

F_2 = \frac{k(Q/2)(Q/2)}{r^2}\\\\ F_2 = \frac{k(Q)(Q)}{4r^2}\\\\F_2 = \frac{1}{4} (\frac{kQ^2}{r^2} )\\\\F_2 = \frac{1}{4} (F)

Therefore, the magnitude of electrostatic force on each charge is quarter of the magnitude of initial electrostatic force.

Mercury has a density of 13.6 g/cm , whereas the density of water is 1.00 g/cm. The pressure of the atmosphere is high enough to
kenny6666 [7]

10.3

Explanation:

Step 1:

The pressure exerted by any liquid column of height, h density d is given by the formula P = h * d * g

Step 2:

It is given that one atmosphere pressure pushes up 76.0 cm of mercury, we need to calculate the level of water that will be pushed by the same pressure.

Step 3:

Since the pressure pushing up mercury and water is the same

h_{mercury} * d_{mercury} * g = h_{water} * d_{water} * g

 h_{water} = \frac{h_{mercury}*d_{mercury} }{d_{water}}  = (13.6 g/cm * 76 cm)/1 g/cm = 1033.6 cm

Step 4:

Now we need to express the answer in meters.

1 m = 100 cm.

1033.6 cm = 10.336 m

This can be rounded off to 10.3 m

Metamorphic rock occurs when you take any other type of rock and put them under ________ and ______________, and they twist and
GrogVix [38]

Answer:

This question appear incomplete

Explanation:

This question appear incomplete because of the absence of options. However, metamorphic rocks are rocks that are formed from other pre-existing rocks under heat and pressure (both are usually high), causing them to twist and melt together. Metamorphism simply means a change in form of something and that's what happens here also.
