An object is held at rest and allowed to drop How far does the object fall in 3.3 seconds?
IgorC [24]
After x seconds, an object will fall \frac{1}{2}at^2 where a is acceleration due to gravity and t is time

so when t=3.3
the distance it will fall is (\frac{1}{2})(9.8\frac{m}{s^2})(3.3m)^2=53.361m
it will fal 53.361 meters

As you build circuits, you will alter voltage, which is the variable. You will measure how changing the voltage affects the curr
Sidana [21]

Answer:

Independent, dependent, resistance

Explanation:

An independent variable is the one which is varied to test changes in the dependent variable. In the given experiment, voltage is an independent variable is which is being varied and it's effect on current (dependent variable) is being tested. Resistance being held constant.

According to Ohm's Law, current is proportional to voltage.

V = I R

R is resistance

How much work is done by the force that moves the charge?
mina [271]

Answer:

The work done by the force is 6μJ

Explanation:

Suppose, A 30 nC charge is moved from a point where V₁ = 130 V to a point where V₂ = -70 V.

We need to calculate the work done by the force

Using formula of work done

W=-q\Delta V

Where, q = charge

\Delta V =potential difference

Put the value into the formula

W=-30\times10^{-9}\times(-70-130)

W=0.000006\ J

W=6\times10^{-6}\ J

W=6\ \mu J

Hence, The work done by the force is 6μJ.
