Answer:
The mechanical energy is converted to potential energy while the kinetic energy is zero
Explanation:
mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object. The total mechanical energy is the sum of these two forms of energy.
The Law of Conservation of Energy: Energy cannot be created or destroyed, but is merely changed from one form into another. This means that potential energy can become kinetic energy, or vice versa, but energy cannot “disappear”.
The mechanical energy is converted to potential energy while the kinetic energy is zero
Answer:
A. 51.42 m.
B. 17.14 s.
Explanation:
Using equations of motion:
vf^2 = vi^2 + 2 * aS
Where,
vf = final velocity
a = acceleration
S = distance to which swan traveled
vi = 0 m/s
6.00^2 = 2 * 0.350S
S = 36/0.7
= 51.42 m.
B.
vf = vi + at
6 = 0 + 0.35t
t = 6/0.35
= 17.14 s.
A=v/t
So therefore 75/0.050= acceleration
So the answer is a= 1500 metres per second per second
Answer:
You are finding acceleration, so it would be 15 m/s2
Explanation:
30 divided by 2
Answer:
All of the above statements are true.
Explanation:
All matter is composed of atoms of which have subatomic particles. Subatomic particles are electrons, protons and neutrons. Each particle has electric charges.
Electrons have a negative charge, protons have a positive charge and neutrons have zero charge.
Between two nearby charges initially at rest, a type of forces, called electrostatic, is always established in such a way that, if the charged particles are small enough so that they can be considered punctual, the following conditions are met:
-
The force established between the two has a direction that coincides with an imaginary straight line that joins the two charges.
- The force exerted on one load points towards the other when the two have different signs, one positive and the other negative. (attractive force).
- The sense of force is directed to the opposite side of the charge when both have the same sign (repulsive force).
