Answer:
Gamma rays
Explanation:
Gamma rays is at the end of the electromagnetic spectrum, and has the highest energy. It propagates through space at 3x10^8 m/s and has the smallest wavelength and the highest frequency. It is given off by atoms of element as they undergo nuclear disintegration.
Answer:
20.85 years
Explanation:
2.61 km = 2610 m
2.07 kW = 2070 W
First we need to calculate the potential energy required to take m = kg of rain cloud to an altitude of 2610 m is
With a P = 2070 W power pump, this can be done within a time frame of
or 658037739/(60*60) = 182788 hours or 182788 / 24 = 7616 days or 7616 / 365.25 = 20.85 years
Here's some example of a statement that describes the way to making a good decision: Make a decision based on the evaluation of consequences involving you and others and take action accordingly. Hope this helps!
Explanation:
The period is the time it takes for the spinner to rotate one revolution, or 2π radians.
T = 2π / ω
T = (2π rad) / (140 rad/s)
T = 0.0449 s
The tangential velocity is the product of the angular velocity and the radius.
v = ωr
v = (140 rad/s) (3.7 cm)
v = 518 cm/s
Answer:
B- Velocity
Explanation:
This means gravity makes the Moon accelerate all the time, even though its speed remains constant.
