You wish to hit a target from several meters away with a charged coin
having a mass of 4.25 g and a charge of +2500 µc. the coin is given
an initial velocity of 12.8m/s, and a downward, uniform electric field
with field strength 27.5n/c exists throughout the region. if you aim
directly at the target and fire the coin horizontally, what magnitude
and direction of uniform magnetic field are needed in the region for the
coin to hit the target?

B = 3.45 T

Explanation:

Given data:

mass of coin = 4.25 g

charge

initial velocity 12.8 m/s

Electric field strength 27.5 N.C

The force due to magnetic field must cancel force due to electric field  and gravitational force

qvB = qE + mg

B = 3.45 T

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

pls mark as brainliest.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
