Yes because something that has been electrically charged can make other things move without touching them ( this is called force without contact)
Hoped this helped :)
Answer:
.
Explanation:
By Newton's Second Law, the acceleration of an object is proportional to the net force on it. In particular, if the mass of the object is , then
.
Rewrite this equation to obtain:
.
In this case, the assumption is that the force is the only force that is acting on the object. Hence, the net force on the object would also be
Make sure that all values are in their standard units. Forces should be in Newtons (same as , and the acceleration of the object should be in meters-per-second-squared (). Apply the equation to find the mass of the object.
.
Answer:
Explanation:
Assuming the dragster accelerates at constant rate, the equation that describes the distance travelled by the dragster after time t is
where
u is the initial velocity
a is the acceleration
If we assume that the dragster starts from rest,
u = 0
And we also know that at t = 3.58 s, the distance covered is
d = 402 m
Solving the formula for a, we find the acceleration:
