Answer:
ride to our expected destination
Answer:
Same
Explanation:
While moving through a magnetic field in a direction perpendicular to a B-field, a continuous force experienced by a charged particle. If this magnetic field remains uniform, the force exerted also remains same and hence the velocity with which the particle is moving remains same. However, the particle is forced to move on a curved path until it forms a complete circle.
Hence, the kinetic energy remains the same because the speed is same
Answers with explanation
1)
Transmission
If all the light passes through a medium without any absorption then transmittance is 100%.
2)
Refraction
Refraction is the bending of a wave when it enters a medium where its speed is different and rays are again refracted when they leave that medium,
3)
Reflection
Reflected rays don't pass through the medium instead rays bounces off an object at an angle.
Answer:
Force(f)= mass x acceleration
Acceleration (a) is the rate of change in velocity.
F=4N
M=0.2kg
a=F/M
a=4/0.2
a=20m/s^2
Explanation:
Answer:
it's is because the heavier the object is the more it will be pulled down by gravity n the lighter the object the lesser the gravity will pull it down
