The electrical charge of particles. The total number of electrons in an atom is always the same as the number of protons in the nucleus. This means atoms have no overall electric charge. The number of protons in an atom is called its atomic hater number.
Answer:
Actual answers are: Renewable energy supplies may not be completely reliable and It is difficult to generate electricity in large quantities using renewable resources.
Explanation:
The results of the experiments should be similar.
Answer:
kinectic energy-in physics kinetic energy of an object is the energy that it possesses due to its motion
- it is defined as the work needed to accelerate a body of a given mass from rest to its started velocity.having
- gained this energy during its acceleration
- The body maintains this kinetic energy unless its speed changes.
potential energy-in physics potential energy is the energy held by an object because of its position relative to other objects,its electric charge,or other factors
- in the case of a bow and arrow ,when archer does work on the bow drawing the string back
- some if the chemical energy of the archer's body is transformed into elastic potential energy in the bent limb of bow
Answer:
The electric force on q₁ is .
Explanation:
Given that,
Charge on
Distance
Charge on at origin
Distance
Charge on
We need to calculate the electric force on q₁
Using formula of electric force
Put the value into the formula
Negative sign shows the attraction force.
We need to calculate the electric force F₁₃
Positive sign shows the repulsive force.
We need to calculate the net electric force
Hence, The electric force on q₁ is .
