Answer:
They all burn fossil fuel is the correct answer.
Explanation:
Cars, power plants, and furnaces all burn fossil fuels such as coal, natural gas, heavy oils, petroleum, oil.
Burning of these fossil fuels results in a release of a huge amount of carbon dioxide and sulfur dioxide gas, into the surrounding that causes air pollution, global warming, acid rain, and these gases present in the environment are highly corrosives and makes suffocating in the environment.
kinematics can be defined as a sub-discipline in physics aimed at understanding the motion of objects without considering the forces that move them.
- Classical mechanics refers to a physical theory that describes the motion of objects.
- Kinematics can be considered a branch of classical mechanics that studies the motion of objects but without considering the forces that move them.
- Kinematics describes the motion of objects and systems by using different types of information such as diagrams, numbers, equations and/or graphs.
In conclusion, kinematics is a sub-discipline in physics aimed at understanding the motion of objects without considering the forces that move them.

Speed= f x λ ( f= frequency. λ = wavelength)
Speed = 2Hz x 6m
= 12m/s
Answer:
The charge that flow through the calculator is 0.384 C
Explanation:
Given;
current drawn by the calculator, I = 0.0008 A
time of current flow, t = 8 min = 8min x 60s = 480 s
The charge that flow through the calculator is given;
q = It
where;
q is the charge that flow through the calculator
I is the current drawn
t is the time
q = 0.0008 x 480
q = 0.384 Coulombs
Therefore, the charge that flow through the calculator is 0.384 C
