Part a)
Magnitude of electric field is given by force per unit charge



Part b)
Electrostatic force on the proton is given as
F = qE


PART C)
Gravitational force is given by



PART d)
Ratio of electric force to weight


Answer:
1.3 m/s
Explanation:
(300N of Fa + 100N' of Fa) - 140N of Ff /200Kg
400N of Fa - 140N* of Ff
260 of ∑F/ 200kg = acceleration
a of piano = 1.3 m/s²
Answer:
the duration between any two events is called time. It's si unit is second.
Answer:
he same direction the magnitude of the resultant is equal to the scalar sum of the magnitude of the forces, but if they are applied in different directions the magnitude must be found using the Pythagorean theorem
Explanation:
When there are several applied forces, if they are all in the same direction the magnitude of the resultant is equal to the scalar sum of the magnitude of the forces, but if they are applied in different directions the magnitude must be found using the Pythagorean theorem, so which the resulting dowry is less than the sum of the magnitudes.
Let's carry out an example with two forces, F1 and F2 of equal magnitudes
if they are in the same direction
F_total = F₁ + F₂ = 2 F
if they are at 90º
F_total =
if they are at 180º
F_total = F₁ -F₂ = 0
<span>Heat in a substance is still an example of heat
or thermal energy. Heat or thermal energy is further defined as the amount of
available molecules of kinetic energy transferred in a specific amount of time.
Heat is nothing if it is not transferred from one object to another. There are
many uses of heat energy. When we are cooking using our stoves, there is heat
energy. When we pour hot water onto our cup of coffee, there is heat energy.</span>
