Answer:

The same book on a table has more potential energy.

Explanation:

The potential energy of a body on Earth is defined as the energy possessed by the virtue of its heights.

The equation for gravitation potential energy is given by

                                    P.E = mgh joules

From the above equation it is evident that when there is a change in the value of 'h', there is a change in the value of P.E

So, as per the above equation, the potential energy of book on floor

                                   P.E = m x g x 0                  ∵ h = 0 at floor

                                    P.E = 0

The same book on the table has some magnitude in 'h' greater than zero

So, the same book on a table has more potential energy.

A magnetic hockey puck (0.40 kg) hits another hockey puck (0.40 kg) at rest and both travel together to the right at 8.0 m/s. Ho
DaniilM [7]
This problem can be solved through the Inelastic Collision Formula:
mass1 x in.velocity1 + mass2 x in.velocity2 = mass1+mass2 (final velocity)

Substituting the values, we have:
0.40 kg x in.velocity1 + 0.40 kg x 0 m/s = 0.80 kg (8.0m/s)

Solving for the unknown initial velocity of the moving hockey puck we have:
in.velocity1 = (6.4 kgm/s - 0) / 0.40 kg
= 16 m/s

What upward gravitational force does a 5600kg elephant exert on the earth?
Anastaziya [24]
Force is determined by multiplying mass and gravity (F= mg). To determine the answer, the mass of the elephant (5600 kg) is multiplied with the gravity (9.8 m/s²). The answer is 5800 N. This is the upward gravitational force that the elephant exerts on the earth.

7. A thin wire was wound 30 times closely over a boiling tube. The total length of the windings as measured was found to be 6.3m
faltersainse [42]

Answer:

Diameter of wire = 0.00021 meters

Explanation:

Given the following data;

Number of windings = 30

Length of windings = 6.3 mm to meters = 0.0063 meters

To find the diameter of the wire, we would use this mathematical expression;

Length of windings = number of windings * diameter of wire

Substituting the values into the expression, we have;

0.0063 = 30 * diameter of wire

Diameter of wire = 0.0063/30

Diameter of wire = 0.00021 meters
