Answer:
ill get back to this question once i get the answer
Explanation:
Acceleration. Angular acceleration: Is the rate of change of the angular velocity of a body with respect to time.
Force. Torque: Is also called rotational force, since an applied torque will change the rotational motion of a body.
Mass. Moment of inertia: It is the resistance that opposes a body to rotates.
Work. Work: In a rotational motion, the work is done by the torque.
Translational kinetic energy. Rotational kinetic energy: is the kinetic energy due to the rotational motion of a body.
Linear momentum. Angular momentum: Represents the quantity of rotational motion of a body.
Impulse. Angular impulse: Is the change in angular momentum of a body.
Answer: The correct answer is an emission line spectrum.
Explanation:
When the electrons are excited to the higher energy level, the energy is absorbed in this case.
When the electrons in the atom step down to lower energy levels in a thin cloud of hot gas then the radiation will emit.
The electron will lose energy in this case in the form of radiation. There will be an emission line spectrum.
Answer:
1.97 x 10^8 m/s
Explanation:
refractive index of crown glass with respect to air, n = 1.52
speed of light in air, c = 3 x 10^8 m/s
Let v be the speed of light in crown glass.
By use of the definition of refractive index
where, n be the refractive index of crown glass, c be the speed of light in vacuum and v be the speed of light in crown glass
v = 1.97 x 10^8 m/s
Thus, the speed of light in crown glass is 1.97 x 10^8 m/s.
choice 3 because the arrow has to be downward for as. and if the divers want to live, the vx has to be going right and not 0 or they would hit the rocks. I hope it's right!
