A speck of dust with mass 12 mg and electric charge 10 μC is released from rest in a uniform electric field of magnitude 850 N/C
Marta_Voda [28]

Answer:

a=708.3m/s^2

Explanation:

The force experimented by a charge <em>q </em>in a uniform electric field <em>E</em><em> </em>is <em>F=qE</em>.

Newton's 2nd Law tells us that the relation between acceleration <em>a</em> a mass <em>m </em>experiments when a force <em>F </em>is applied to it is <em>F=ma</em>.

Combining these equations we have <em>am=qE</em>, and since we want the acceleration of the speck of dust, we substitute our values:

a=\frac{qE}{m}=\frac{(10\times10^{-6}C)(850N/C)}{12\times10^{-6}Kg}=708.3m/s^2

FinnZ [79.3K]

Answer:

Explanation:

If a car is moving to the left with constant velocity, one can conclude that

there must be no forces applied to the car .  The net force applied to the car is zero.

Since there is no acceleration ,no net force is applied , hence no force acts on the car.

A 100 sprinter starts from rest and final velocity of 18.8m/s what is the sprinter average acceleration if takes him 10.6 s to r
AlladinOne [14]

Answer: 1.77 m/s²

Explanation: acceleration is expressed in:

a= ∆v / t = vf-vi/t

a= 18.8 m/s - 0 / 10.6 s

a= 1.77 m/s²
