Answer:
a female polar bear weighs 550 kg
The frequency of light from a laser is 4.878 x10^ 14 s-1 hertz
<h3>Steps</h3>
v= c/ lambda
c= 3.00 x10^8 m/s
nm into meters
615nm (1m/ 1x10^9 nm) = 6.15x 10^-7 m
use frequency formula
v = 3.00 x10^8 m/s // 6.15 x10 ^-7
v = 4.878 x10^ 14 s-1 hertz
The frequency of light from a laser is 4.878 x10^ 14 s-1 hertz
<h3>What do you mean by frequency?</h3>
- The quantity of waves that pass a set location in a predetermined period of time is known as frequency.
- Therefore, if a wave passes through in half a second, the frequency is 2 per second.
- The frequency is 100 times per hour if it takes 1/100 of an hour.

That depends on what its speed was at the beginning of 5 seconds,
and on what exactly happened to it.
If it got pushed off of the window sill and fell to the ground below,
then the answer would depend on how high the window sill is.
If the flower pot kept falling for the whole 5 seconds, then its speed
would be <em>49 meters per second</em> at the end of the 5 seconds. That's
because here on Earth, gravity increases the speed of falling things
by 9.8 meters per second for every second they fall.
Naturally, this answer is only true if the window sill is more than
122.5 meters above the ground ... about 402 feet, or 40 floors.
If it's lower than that, then the flower pot hits the ground in less
than 5 seconds, and its speed at the end of 5 seconds is zero.
By the way ...
-- It makes no difference how much the flower pot weighs.
All objects fall with the same acceleration, and hit the ground
at the same time.
-- 5 kilograms is a mass, not a weight.
Answer:
Yes, I agree with rich
Explanation:
Yes I agree with rich.
Thus is because;
The electromagnetic process is what will determine how electromagnetic radiation will be emitted. Now, the mode of travel of electromagnetic energy is in the form of waves and then the wavelength of these waves is what will enable us know the form of energy. This includes light, x-rays, gamma rays e.t.c. This means that light and the others are just parts of the spectrum emitted and are called photons.
Thus, light can be said to be electromagnetic radiation.
