Both climate and weather measure conditions in the atmosphere.
One radian per second is equal to 206265 seconds of arc. (On a plane angle)
Answer:
D. You will feel the same weight as you do on Earth
Explanation:
In free space, she is suppose to be weightless.
Free fall can be described as body in motion where the body is under the effect of acceleration due to gravity only and no other acceleration..
Since I am accelerating away from her at an acceleration of 1g
Then,
F=ma, where a=g
Then F=mg
Since my weight on earth is W=mg
This is equals to my weight in the spaceship, then I will feel the same weights as I do on earth.

Answer:</h3>
49 N
<h3>
Explanation:</h3>
<u>We are given;</u>
- Mass of the brick as 3 kg
- The coefficient of friction as 0.6
We are required to determine the force that must be applied by the woman so the brick does not fall.
- We need to importantly note that;
- For the brick not to fall the, the force due to gravity is equal to the friction force acting on the brick.
- That is; Friction force = Mg
But; Friction force = μ F
Therefore;
μ F = mg
0.6 F = 3 × 9.8
0.6 F = 29.4
F = 49 N
Therefore, she must use a force of 49 N
Answer:
Explanation:
First of all, let's calculate the energy of a single photon of wavelength
which is given by
The power of the flash is
and the time it lasts is
so the total energy delivered in one flash is
This energy contains exactly N photons each of energy 
, so the number of photons emitted in one flash is
