Answer:
t=v/a
Explanation:
Acceleration is defined as the rate of change of velocity with time. It is mathematically expressed as;
Acceleration =
The change in velocity per unit of time is the acceleration
From this equation;
time =
This expression is analogous to the expression chosen.
Answer:
The answer is C.
Explanation:
If there are brake lights then you should drive slower.
Answer:
4.23 beats / seconds
Explanation:
Frequency heard = f = f₁ - f₂
f₂ = f₁ √ ( F₂ / F₁)
f = f₁ - f₁ √ ( F₂ / F₁) = f₁ ( 1 - √ ( F₂ / F₁) = 523 Hz ( 1 - 0.9919 ) = 4.23 beats / seconds
It is force because work/distance= force
