Answer:
Explanation:
Mass of a hockey puck, m = 0.17 kg
Force exerted by the hockey puck, F' = 35 N
The force of friction, f = 2.7 N
We need to find the acceleration of the hockey puck.
Net force, F=F'-f
F=35-2.7
F=32.3 N
Now, using second law of motion,
F = ma
a is the acceleration of the hockey puck
So, the acceleration of the hockey puck is 
.
Answer:
The magnitude is: 
The direction of E is in the negative x-direction.
Explanation:
The electric field equation is:
Where:
- Q is the charge (we can choose the electron or the proton)
- r is the distance (in our case is at the midpoint 973/2 nm)
- k is the Coulomb constant (
)
Using the electron charge (
)
The magnitude is:
The direction of E is in the negative x-direction.

Answer:
Ecliptic
Explanation:
You asked for the term that is used to describe Earth going around the sun
The ecliptic is the path the sun, moon, and planets take across the sky as seen from Earth. It best defines the plane of the Earth's orbit around the sun. The imaginary line can best be visualized in the days just before full moon.

The correct answer is '44'.
In fact, the atom of an element has an equal number of protons and electrons: therefore, if element X has 44 protons, it should have 44 electrons as well.
For curiosity: the chemical element with 44 protons and 33 electrons is Ruthenium.
An electric generator works on the principle of Faraday's law of electromagnetic induction. Faraday's law of electromagnetic induction states that “whenever a current carrying conductor are placed in the magnetic field, then a flux is induces in the circuit due to which a current start to flow in the rotor also.
