Answer:
a = 30 km / h²
Explanation:
Dado que
Velocidad inicial, u = 70 km / h
Velocidad final, v = 95 km / h
Tiempo, t = 30 s = 0.1 h
Lo sabemos
v = u + a t
a = aceleración
Ahora poniendo los valores en la ecuación anterior


Por lo tanto, la aceleración será
a = 30 km / h²
Answer:
The answer is 5 meters per second.
Answer:
Output force = 300 N
Explanation:
Given that,
The mechanical advantage of a lever, m = 3
Input force, 
We need to find the output force. The ratio of output force to the input force is called the mechanical advantage of the lever. So,

So, the output force is 300 N.
The statement is false. Sound REQUIRES a material medium
in order to propagate from one place to another..
