Answer:
When you lift the ball, you are doing work to increase its gravitational potential energy. When you then release the ball, gravitational energy is transformed into kinetic energy as the ball falls. When the ball hits the floor, the ball's shape changes as it flattens against the floor.
Explanation:thats should be the way^^ in explaining
<span>Torque = I * α
I = ½ * m * r^2 = ½ * 0.2 * 0.125^2 = 0.0015625
As the disk rotates one time, it rotates an angle of 2 π radians.
Total angle = 1600 * 2 π = 3200 * π
One minute is 60 seconds. To determine its initial angular velocity, divide this angle by 60.
ω = 53⅓ * π
This is approximately 167.55 rad/s. To determine the angular acceleration, divide by 4.1 seconds.
α = 53⅓ * π ÷ 4.1
This is approximately 4.09 rad/s^2
Torque = 0.0015625 * (53⅓ * π ÷ 4.1)
This is approximately 0.0639 N * m.

The pairs of triangles that can be proven congruent by the hl theorem is the right angled triangle.
<h3>What is mearnt be the HL theorm?</h3>
The HL theorem is also known as the Hypothenus Leg theorem, it states that "the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent."

Answer:
the resultant velocity is Zero
Explanation:
by the rule of adding and subtracting factors, we know that; when the force acting on an object is from east & north we add and with forces acting from South & west we minus.
Therefore:
1) List the forces down:
the 100m/s acting west is (-) while
the other 100m/s is acting in easterly direction
so it is (+)
2) Add the forces:
-100+100=0
therefore the answer is 0m/s for the the resultant velocity
hope I'm right
Answer:
If you use P = 2 * pi * (L / g)^1/2 for the period of the simple pendulum
g = 4 * pi^2 * 1.2 / 2.8^2 = 6.04 m/s2
Note: omega = 2 pi * f = 2 pi / P and omega = (g / L)^1/2
