Answer:
A)
B)
Explanation:
Given:
mass of car,
A)
frequency of spring oscillation,
We knkow the formula for spring oscillation frequency:
Now as we know that the springs are in parallel and their stiffness constant gets added up in parallel.
<u>So, the stiffness of each spring is (as they are identical):</u>
B)
given that 4 passengers of mass 70 kg each are in the car, then the oscillation frequency:
Answer:
It depends if they have the same lightbulb in them.
Explanation:
Reflection from such a rough surface is called diffuse reflection and appears matte
The two objects with electrical charges interact, which affect the strength of that interaction <span>amount of charge. The answer is letter A. The rest of the choices do not answer the question above.</span>
