Answer:
The magnitude of acceleration is 3 m/s^2.
Explanation:
The net force along North-South direction is 18-24=-6 N.
The net force along East-West direction is 16-16=0 N
The net magnitude of force is square root of (-6)^2+0^2 which is 6 N.
By Newton's Second law,
Force F=ma
Therefore acceleration a=F/m
a=6/2
a=3 m/s^2

Answer:
Explanation:
Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. ... The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.
<span>one year is 365, 1 day is 24 hours, 1 hour is 60 minutes, 60 minutes is 60 seconds, thus (365 * 24 * 60 * 60) = 31,536,000
one year is equal to 31,536,000 seconds. the plate has a speed of 4.8 cm every 31,536,000 seconds. lets find out how far it goes in 40 seconds. (4.8/31,536,000)*40 = 0.00000608828
The plate moves 0.00000608828 cm every 40 seconds</span>
<span>A. An impulse of a force changes the momentum of a body and has the same units and dimensions as momentum.</span>
Answer:
a baseball flying through the air at 90 miles per hour
Explanation:
For the question, Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If the velocity is doubled the kinetic energy will increase by a factor of four.
