Answer:
2 minutes or 120 seconds
Explanation:
The answer is 2 minutes or 120 seconds because 36 km is 36000 m and 36000 divided by 300 is 120, so the answer is 120 seconds, and converted to 2 minutes. Hope it helps!
Answer:
The wavelength of observed light on earth is 568.5 nm
Explanation:
Given that,
Velocity of spaceship
Wavelength of laser
We need to calculate the wavelength of observed light on earth
Using formula of wavelength
Hence, The wavelength of observed light on earth is 568.5 nm
I’m pretty sure the answer is A
Answer:
The answer is that the worker should not be worried.
Explanation:
At equilibrium position, the net torque is equal to zero
∑tnet = 0
((-mg) * (D/2)) + ((-mg) * (D-d)) + (T * sinθ * D) = 0
Clearing the tension in the cable T:
Since this tension (14727.24 N) is less than the nominal tension (15354 N), the worker should not be concerned.
Answer:
- <u>Because in both kind of motions, the position is periodically repeated. Both are simple harmonic motions.</u>
Explanation:
<em>Moving back and forth</em> means that the moving object goes through the same position every time a certain period of time elapses.
The same is true for the <em>circular motion</em>, every time the object completes a turn, the object is in the same position.
They are examples of simple harmonic motions. The time it takes the object to repeat a complete cycle is called period.
Therefore, in a grahp of position versus time, the curve that represents the position repeats itself every so often equal to one period, both for moving back and forth and for moving in a circle.
