Answer: Venus
Explanation: Venus is the slowest revolving planet in our solar system, rotating once every 243 days, making.
The correct option is (A) 2.5 m/s
Explanation:
Since,
v = fλ ---- (1)
where v = speed of the wave
f = frequency of the wave = 5 Hz
λ = wavelength of the wave = 0.5
Plug in the value in (1):
(1) => v = 5 * 0.5
v = 2.5 m/s
Answer:
Campfires top the list of ways that humans start wildfires, the U.S. Forest Service said. Typically, campfires either grow out of control and the people who built the fire do not have a way to stop it, or they fail to extinguish the fire properly, allowing the fire to re-ignite after they leave.
Explanation:
Answer:
2.79 m
Explanation:
Use the static equilibrium condition, net torque actin on the system is zero.
solve for the distance of the person from the wall x
now putting the values we get
= 2.79 m
Answer:
The height of the cliff is 28.57 m.
Explanation:
Given;
initial velocity of the rock, u = 12.6 m/s
time of motion, t = 1.45 s
The height of the cliff is given by;
h = ut + ¹/₂gt²
h = (12.6 x 1.45) + ¹/₂(9.8)(1.45)²
h = 18.27 + 10.30
h = 28.57 m
Therefore, the height of the cliff is 28.57 m.
