Answer:
L = ¼ k g / m
Explanation:
This is an interesting exercise, in the first case the spring bounces under its own weight and in the second it oscillates under its own weight.
The first case angular velocity, spring mass system is
w₁² = k / m
The second case the angular velocity is
w₂² = L / g
They tell us
w₂ = ½ w₁
Let's replace and calculate
√ (L / g) = ½ √ (k / m)
L / g = ¼ k / m
L = ¼ k g / m
No. For one thing, when it comes, it flows too fast to catch it and store it. And second, you never know WHERE to set up your equipment.
NT
=
r / β
where NT is the threshold density, r is the recovery and death rate and β is the transmission coefficient.
= 0.4 / 0.2
= 2
Odometer: tells you the distance traveled by vehicle since it was new (or when last reset)
Speedometer: tells you the velocity of the vehicle at that moment.
Answer:
Newton's Third Law
Explanation:
Newton's third law
Newton's third law: “for every action, there is an equal and opposite reaction.” This is where you get the bounce. When you push down on the trampoline (or fall downward onto the trampoline bed), Newton's third law says that an equal and opposite reaction pushes back.
