According to Newton’s second law acceleration= force/mass
So acceleration = 10/2
= 5m/s^2
Answer:
Explanation:
3. The word circuit means "go around", therefore a circuit is a pathway or closed path around which electricity (or water) flows.
4. Electrons flowing through a wire can be compared to water flowing through a hose. Once the flow of electrons or water is going, work, is performed.
5. You would get shocked in a bumper car by touching the floor and the ceiling at the same time. This means you are completing the circuit allowing electricity to flow.
6. Electricity from a wall outlet has enough energy to stop your
heart.
7. Electricity is the flow of electrons, because electrons move or jump from atom to atom.
8. Materials that allow electrons to move easily from atom to atom are called conductors.
9. Materials that do not allow electrons to flow easily are called insulators.
10. Semi- conductors are materials that are somewhere in between
.
11. Voltage is the force or pressure of electricity and is compared to the amount of water pressure in a hose.
12. Current (amps
) is the amount of electricity and is compared to the amount of water in a hose
.
13. Watts (power) is the term for work performed by electricity.
Answer:
A. The potential energy of the positively charge proton from 5v to 7.5v will increase because in an electric field work is done on the proton to move it to a point of higher potential
B. when an electron is moved from 7.5v to 5v it loses potential energy due to the charges lost so as to bring it to a point of lower potential
Explanation:
The value of the constant K in the temperature equation is 32.
The given parameters:
- 40⁰C corresponds to 104 ⁰F
The value of K for which the value of the temperature at 40 degrees Celsius corresponds to 104 degrees Fahrenheit is calculated as follows;
Thus, the value of the constant K in the temperature equation is 32.

Answer:
m' = 20.1024 kg
Explanation:
Given that for standard object
m = 7.98 kg
a= 2.5244 m/s²
From Second law of Newtons
F= m a
Now by putting the values
F = 2.5244 x 7.98 N
F= 20.144 N
In second object
F'= m ' a'
F' = F ( given that)
20.144 = 1.0021 m'
m' = 20.1024 kg
