Answer:
Acceleration of the plane, a = 5.4 g
Explanation:
It is given that,
Speed of the jet plane, v = 1890 km/h = 525 m/s
Radius of the arc, r = 5.20 km = 5200 m
The plane is moving in the circular path, the centripetal acceleration will act on it. It is given by :
We know that, the value of g is,
So, the acceleration of the plane is 5.4 g. Hence, this is the required solution.
The charge on the positive plate is 1.734* C
Given,
V=9v, R=0.066m Gap(G)=2.0mm=0.0020m ∈=8.85*
We know C=∈ * = 8.85*
*
=19.275*
F
Also, Q = C V = 19.275* * 9 = 1.734*
C
When charged matter is exposed to an electromagnetic field, its electric charge—a property of matter—causes it to feel a force. A charge on an electric field might be positive or negative. Like and unlike charges are attracted to one another while being repelled by the other. Neutral describes a thing without any net charge. Electric charge is a conserved property; in an isolated system, the net charge, or the sum of the positive and negative charges, is constant. Subatomic particles transport electrical charge. The protons in atoms' nuclei carry positive charge in normal matter, while the electrons carry negative charge.

Explanation:
It is given that,
The distance from the pitcher's mound to the batter is 43 feet, d = 43 feet = 0.00814 miles
Speed with which ball leaves the ball, v = 110 mph
Let t is the time elapses between the hit and the ball reaching the pitcher. It is given by :
t = 0.000074 hours
or
t = 0.2664 seconds
So, the time between the hit and the ball reaching the pitcher is 0.2664 seconds. Hence, this is the required solution.
