The premotor cortex of the brain is responsible for this type of behavior. Mirror neurons are activated during these times. The mirror neuron situated in the premotor cortex copies the behaviors or feelings observed, therefore, people watching exhibit the same behavior and feelings as the player itself when they lose a game.

Two identical conducting spheres, A and B, carry equal charge. They are separated by a distance much larger than their diameters

Vesnalui [34]

Answer:

C. $\frac{3F}{8}$

Explanation:

Let initial charges on both spheres be, $q$

$F=\frac{Kq^2}{d^2} \ \ \ \ \ \ \ \ \ \ \_i$

When the sphere C is touched by A, the final charges on both will be, $\frac{q}{2}$

#Now, when C is touched by B, the final charges on both of them will be:

$q_c=q_d=\frac{q/2+q}{2}\\\\=\frac{3q}{4}\\$

Now the force between A and B is calculated as:

$F\prime=\frac{k\times\frac{q}{2}\times \frac{3q}{4}}{d^2}\\F\prime=\frac{3F}{8}$

Hence the electrostatic force becomes 3F/8

In your own words, describe the purpose of using a chemical equation.

Scilla [17]

Chemical equations show how chemicals interact when a reaction occurs. They use symbols and formulas to show the chemical reaction so that chemical names do not need to be written out. They also help keep track of all elements and the number of atoms of each element on each side of the equation.

Suppose a treadmill has an average acceleration of .0050 m/s2. How much does it's speed changer after 4.8 minutes?

avanturin [10]

This one is nice and straight forward :)

simply calculate how many seconds are in 4.8 minutes like this:
4.8min x 60s = 288s

Then to find the ∆v (∆v = symbol for change in velocity) multiply the acceleration 0.0050m/s^2 by 288s
∆v = 1.44m/s

0.0050m/s $x^{2}$
