Aspherical cavity is excised from the inside of the sphere. the cavity has radius a4 and is centered at position h⃗ , where |h⃗ |< 34a, so that the entire cavity is contained within the larger sphere. find the electric field inside the cavity. express your answer as a vector in terms of any or all of ρ (greek letter rho), ϵ0, r⃗ , and h⃗ .

when it gains or loses electrons

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

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
