Acharge -364e is uniformly distributed along a circular arc of radius 6.10 cm, which subtends an angle of 56o. what is the linear charge density along the arc? (b) a charge -364e is uniformly distributed over one face of a circular disk of radius 4.70 cm. what is the surface charge density over that face? (c) a charge -364e is uniformly distributed over the surface of a sphere of radius 5.00 cm. what is the surface charge density over that surface? (d) a charge -364e is uniformly spread through the volume of a sphere of radius 4.10 cm. what is the volume charge density in that sphere?

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

there are no components of a physical goal mentioned on the list of choices that you've provided.
