Answer:

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:

Answer:
the speed of sound is 331.3 meters per second (1,087 feet per second) in dry air at 0 degrees Celsius
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.
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
