When object travels with uniform velocity, no force acts on it. hence , yes.
The magnetic field lines start at a magnet's north pole and end at the south pole.
A. They begin on north poles and end on south poles.
<u>Explanation:</u>
Magnetic field lines are a visual instrument used to speak to attractive fields. They portray the bearing of the attractive power on a north monopole at some random position. The north post of one magnet draws in the south shaft however repulses the north shaft of another magnet dissimilar to shafts pull in and like shafts repulse.
A metal is a magnet on the off chance that it repulses a known magnet. Be that as it may, the Magnetic field lines don't simply end at the tip of the magnet. They go directly through it so that inside the magnet the attractive field focuses from the south shaft toward the north post.

Answer:
The charge carried by the droplet is
Explanation:
Given that,
Distance =8.4 cm
Time = 0.250 s
Suppose tiny droplets of oil acquire a small negative charge while dropping through a vacuum in an experiment. An electric field of magnitude points straight down and if the mass of the droplet is
We need to calculate the acceleration
Using equation of motion
Put the value into the formula
We need to calculate the charge carried by the droplet
Using formula of electric filed
Put the value into the formula
Hence, The charge carried by the droplet is
Answer:
1×10^2
Explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
