Everything in the universe that is not a star reflects light from Stars. Otherwise you can't see it.
Answer:
W = 7.5 J
Explanation:
W = KE
W = ½mv² = ½0.6(5²) = 7.5 J
Niño, piedra y ascensor están todos en el mismo marco de referencia inercial.

Explanation:
The magnetic force acting on the charged particle in magnetic field is given by :

Here,
q is the charged particle
v is the speed of particle
B is magnetic field
is the angle between the v and B.
The correct statements for the magnetic force are :
- An electric charge moving perpendicular to a magnetic field experiences a magnetic force. In this case,
. It will experience maximum force. - The direction of the magnetic force acting on a moving electric charge in a magnetic field is perpendicular to the direction of motion.
- A magnetic force is exerted on an electric charge moving through a uniform magnetic field.
- The direction of the magnetic force acting on a moving charge in a magnetic field is perpendicular to the direction of the magnetic field.
The maximum friction that can be generated between two static surfaces in contact with each other. Once a force applied to the two surfaces exceeds the limiting friction, motion will occur. For two dry surfaces, the limiting friction is a product of the normal reaction force and the coefficient of limiting friction.
