Answer:
work done by fuel is conversion of chemical energy into mechanical whereas work done by moving object is due to its displacement by the application of force. actually, both of them give same meaning
Answer:
cart displacement is 66 m
Explanation:
given data
velocity = 5 m/s
acceleration = 2 m/s²
time = 6 s
to find out
What is the
magnitude of cart displacement
solution
we will apply here equation of motion to find displacement that is
s = ut + 0.5×at² .............1
here s id displacement and u is velocity and a is acceleration and time is t here
put all value in equation 1
s = ut + 0.5×at²
s = 5(6) + 0.5×(2)×6²
s = 66
so cart displacement is 66 m
Answer:
Explanation:
Given
Work required to stretch 1 ft is 12 ft-lb
and we have to find work required to stretch 3 in.
i.e. 
divide (1)&(2)
Answer:
- Cool, dense air begins to sink downward.
- A high-pressure system forms.
- Pressure differences cause wind to blow outward.
- The skies clear, making way for pleasant weather.
Explanation:
The air near the land warms up and rises. Cool dense air sinks being heavier. This creates a pressure difference. A high pressure system forms. This difference leads to blowing of wind from High pressure to low pressure area. Eventually sky gets clear and we experience pleasant weather. Hence, the correct order to describe this is:
- Cool, dense air begins to sink downward.
- A high-pressure system forms.
- Pressure differences cause wind to blow outward.
- The skies clear, making way for pleasant weather.
