Answer:
190 000 m
Explanation:
1km = 1000m
--> 190 km = 190 x 1000 = 190 000 m
Answer:
E = 0.01 J
Explanation:
Given that,
The mass of the cart, m = 0.15 kg
The force constant of the spring, k = 3.58 N/m
The amplitude of the oscillations, A = 7.5 cm = 0.075 m
We need to find the total mechanical energy of the system. It can be given by the formula as follows :

Put all the values,

So, the value of total mechanical energy is equal to 0.01 J.
Speed of a wave = (wavelength) x (frequency)
Speed of this wave = (100 m) x (5 / sec)
<em>Speed = 500 m/s</em> (about 1,118 miles per hour)
