Mass = Weight/g
= 1225 N/9.81 m/s^2
= 124.872579 kg
(rounded-off in 3 significant figures) = 125 kg
NOTE: I truly apologize if my answer is incorrect. I still hope this helped! :) (a brainliest would be much appreciated!)
When you drop something, gravity creates a force.
Blue would bend the most, since it has a greater refractive index. It has more energy and a shorter wavelength, so it slows.
If you are stationary, but in/on a moving vehicle/object you can be at rest and moving at then same time.
<u>Explanation</u>:
- A particle, when viewed from a given frame of reference, cannot be both at rest and in motion. However, in one frame of reference, a particle can be in motion whereas in another frame of reference the particle is in motion.
- For example, if you are seated in a plane, the plane is stationary in that reference frame and the Earth moves under it, but in the reference frame of the Earth, the plane is moving concerning the Earth. When you are standing still on Earth, in your frame of reference, the Earth is stationary, and the Sun and stars move around the Earth.
- However, in the frame of reference of the center of our solar system, the Earth orbits the Sun and the Sun are perturb slightly by the rest of the planets, but the rest of the galaxy orbits our solar system. Of course, in rest from our Galaxy, our solar system orbits a giant black hole at its center.
The concept required to solve this problem is that related to the Isobaric process. Isobaric process is understood as the process in which changes occur at constant pressure. From the first law of thermodynamics this can be expressed as,
Here,
P = Pressure
dV = Differential of Volume
As the Pressure is constant we have,
Replacing
Therefore the correct answer is A.
