Answer:
Explanation:
Time period of Simple pendulum is given by
where L=length of Pendulum
g=acceleration due to gravity
(a)When elevator is accelerating upward with
effective g will be g+a=9.8+5
therefore time period will decrease
(b)When elevator is moving upward with 5 m/s
effective g will be g as there is no added acceleration
therefore time period will remain same
(c)When elevator is accelerating downward with
effective g will be g-a=9.8-5
therefore time period will increase
(d)When elevator is accelerating downward with
effective g will be g-9.8=0
therefore time period will become infinite
Answer:
Rocket 2 has highest acceleration.
Explanation:
Net force,
F = mass (m) × acceleration (a)
We have,
m₁ = 4.25 kg and F = 120 N
m₂ = 3.25 kg, F₂ = 120 N
m₃ = 5.5 kg, F₃ = 120 N
m₄ = 4.5 kg, F₄ = 120 N
Hence, it can be seen that the highest acceleration is of rocket 2.
