Answer: 1.32 m/s^2
Explanation:
Centripetal acceleration is given by the formula
a = ( v^2 ) / r
where a is centripetal acceleration, v is velocity and r is radius.
We know that,
v = 5 m/s
r = 19m
Now,
a = ( v^2 ) / r
a = ( 5^2 ) / 19
a = 25 / 19
a = 1.32 m/s^2
Answer:
no lol.. is this actually for school?
Answer:
Fundamental quantities are quantities that were created to measure a object/substance which are the basis on which derived quantities are formed, where as derived quantities are created by extracting variables from the fundamental quantities.
Answer:
D) Reduce the internal friction of the engine's parts.
Explanation:
To increase the efficiency of the car's engine, an engineer most like has to reduce the friction within the internal engine parts. Reducing these friction reduces the useful energy lost as heat in these internal parts of the engine, when the engine parts do work against friction to move. In most everyday activities, engines and machines, energy is usually lost as heat due to frictional forces arising from two or more surfaces in contact.
