Answer:
Speed is 1.962*10^-3m/s
Explanation:
Given that
Mass of proton==1.67*10^-27
Acceleration due to gravity (g)=9.81m/s^2
Angle of inclination A=90°
Charge (q)=1.6*10^-19
Magnetic field (B)=5*10^-5T
From lorentz force
It can be seen that
F=w =mg=qvBsinA
We're Velocity (v)=mg /qBsinA
V=1.67*10-27*9.81/1.6*10^-19*5*10^-5*sin90
V=1.962*10^-3m/s
The answer is right. The point and the 200 N sign maybe on the left side but the direction can be going right. I just took the quiz today, I wouldn't give the wrong answer cause i'm not a liar. -_-
The answer is:
C

Explanation:
The core of Earth is the hottest, so that is where the heat comes from. It moves outwards to the mantle.
Explanation:
Thermal energy is basically the energy derived from heat when there is a temperature change in a body.
Kinetic energy is the energy due to the motion of a body.
Potential energy is the energy at rest or due to the position of a body.
- Thermal energy is highly related to kinetic and potential energy.
- Thermal energy is a type of kinetic energy because it causes the motion of the particles in a body.
- An increase in thermal energy gives the particles more energy to move and then, their kinetic energy increases.
- Kinetic energy is directly related to thermal energy.
- A low thermal energy increases the potential energy in a body.
- A body at rest will exert its maximum potential energy.

Answer:
Distance, d = 99990 meters
Explanation:
It is given that,
Speed of the train, v = 200 km/h = 55.55 m/s
Time taken, t = 1800 s
Let d is the distance covered by the train. We know that the speed of an object is given by total distance covered divided by total time taken. Mathematically, it is given by :



d = 99990 m
So, the distance covered by the train is 99990 meters. Hence, this is the required solution.
