A car is traveling at a velocity of 7.5 m/s. How far will it get in 34 sec
1 answer:
Answer:
255 m
Explanation:
The car is moving by uniform motion (constant velocity), so we can calculate the distance it travels by using the equation
where
d is the distance travelled
v is the velocity of the car
t is the time interval
In this problem:
v = 7.5 m/s is the velocity of the car
t = 34 s is the time interval
Therefore, the distance covered by the car is

Answer:
A. 181.24 N
Explanation:
The magnitude of hte electrostatic force between two charged objects is given by the equation
where
k is the Coulomb's constant
q1, q2 are the magnitudes of the two charges
r is the separation between the charges
In this problem, we have:
is the magnitude of the 1st charge
is the magnitude of the 2nd charge
r = 2.5 cm = 0.025 m is the separation between the charges
Therefore, the magnitude of the electric force is:
So, the closest answer is
A) 181.24 N
