A. True
It is true that mass is a measure of the quantity of matter in an object.
Velocity includes direction, for instance going 140 MPH is speed but going 140 MPH North is velocity
Answer:
It will have an acceleration of .
Explanation:
Newton’s second law is defined as:
(1)
Equation 1 can be rewritten for the case of the acceleration:
The force and the acceleration are directly proportional (if one increase the other will increase too).
But 1 N is equivalent to
So a body will have an acceleration as a consequence of the action of a force.
<u>Answer</u>:
(C) The positive charge of the alpha particles and the negative charge of the electrons are the properties Rutherford used in his experiment
<u>Explanation</u>:
In his scattering experiment, scientist Ernest Rutherford used the property of positively charged alpha particles and negatively charge electrons. He performed this experiment by passing some of the alpha particles through a gold foil. The result was that the some alpha particles scattered while some passed through the gold foil without collision.
He concluded that the alpha particles are centrally positively charged and needed a large amount repelling force. This experiment of Rutherford is also known as Rutherford model of atom. This experiment helped him in doing so many other discoveries.
I am so sorry, but I do not know what section you are talking about. I hope you find the answer.
