Answer: 7750 J
Explanation:
Mechanical energy is potential energy added to kinetic energy.
5000 + 2750 J = 7750 J
If you are given distance and a period of time, you can calculate
the speed. The velocity of an object is the rate of change of its position with
respect to a frame of reference, and is a function of time. Velocity is
equivalent to a specification of its speed and direction of motion (e.g. 60
km/h to the north).
Answer:
0.0000109261200583 s
0.0109261200583
Explanation:
= Distance from right ear = 3 m
s = Distance between ears = 15 cm
v = Speed of sound in air = 343 m/s
Distance between the left ear and the bird
Time
Time difference would be
The time difference is 0.0000109261200583 s
Time period is given by
The ratio is
The ratio is 0.0109261200583
Answer:Both are correct
Explanation:
Both are correct because
Mechanical efficiency is the dimensionless term which is the ratio of brake horsepower to the Indicated horse Power
Where brake power is the Power obtained at the crankshaft and
Indicated horsepower is the power obtained in the combustion chamber and this power is the loss in the form of friction.
Volumetric efficiency is the ratio of actual fuel intake to the maximum air fuel that could be taken.
