Answer:
It will take 4 sec rock to comes its original point
Explanation:
It is given that the rock comes to its original point
So displacement S = 0 m
Initial velocity u = 19.6 m/sec
Acceleration due to gravity 
According to second equation of motion 
t = 4 sec
Newton’s second law states that force is the product of
mass and acceleration. This is expressed mathematically as:
F = m * a
Where F = force, m = mass, a = acceleration
Since in the given problem, the force is constant or same
force is acting upon two objects. Therefore we can simply equate the expression
m * a of the 2 objects.
m1 * a1 = m2 * a2
Where m1 = 2 kg, a1 = 38 m/s^2, m2 = 19 kg. Therefore
finding for a2:
2 kg * 38 m/s^2 = 19 kg * a2
<span>a2 = 4 m/s^2 (ANSWER)</span>
When discharging equivalent of 0% starting voltage will the capacitor reach after 5RC.
V(t) = V0e-t/RC = V0b initially.
<h3>What is capacitor?</h3>
- In an electric field, a capacitor is a device that stores electrical energy. It has two terminals and is a passive electrical component.
- Capacitance refers to a capacitor's effect.
- The terminals in a capacitor are connected to two metal plates that are spaced apart by a dielectric, a non-conducting material.
- Two pieces of aluminum foil, along with a piece of paper, can be used to create a capacitor (and some electrical clips).
- It won't have a lot of storage capacity, so it won't be a great capacitor, but it will still function.
<h3>What are the different types of capacitors?</h3>
The numerous kinds of capacitors and their applications.
- Frequently utilized in radio tuning circuits is air.
- Mylar: The material most frequently used in timer circuits for clocks, alarms, and counting.
- Good for high-voltage applications is glass.
- Ceramic is used in X-ray, MRI, and other high-frequency devices.
- a powerful capacitor fuels hybrid and electric vehicles.

Answer:
Answer Below!!
Explanation:
STEP 1: Draw a straight line with a ruler. STEP 2:Put the pin of a compass at the end of the line you want to bisect.Set the compass to more than half the length of the line and draw an arc crossing the line. STEP 3: Keep the width of the compass the same, and from the opposite end of the line draw another arc.
