The direction in which the magnetic force is acting on the charge is upwards.
<h3>What is Magnetic force?</h3>
This is the attraction and repulsion which usually occurs during the motion of electrically charged particles.
In the magnetic field, the charge is moving to the left. Therefore the direction the magnetic force is acting on the charge is upwards which is gotten via right hand rule.

Answer:
The angular acceleration of the blades is .
Explanation:
Given that,
Initial angular velocity of the blade of fan,
Final angular velocity of the blade of a fan,
Time, t = 5.95 s
The angular acceleration of the blades is equal to the rate of change of its angular velocity. It is given by :
So, the magnitude of the angular acceleration of the blades is .
Answer:
Th average force impact is
Explanation:
From the question we are told that
The mass of the golf ball is
The angle made is
The range of the golf ball is
The duration of contact is
Generally the range of the golf ball is mathematically represented as
Here v is the velocity with which the golf club propelled it with, making v the subject
=>
=>
Generally the change in momentum of the golf ball is mathematically represented as
here u is the initial velocity of the ball before being stroked and the value is 0 m/s
=>
Generally the average force of impact is mathematically represented as
=>
=>
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.
Is this a trick question?
<u><em> . . a closed system doesn't exchange any matter with its surroundings and isn't subject to any external force, it is essentially an isolated system.</em></u>
In the case of a bathtub, <u><em>it is </em></u><em><u>open immediately </u></em><u><em>to evaporation</em></u>, so the truth is this system is <u><em>never </em></u>closed
<u><em>the correct answer is E.) none of the above</em></u>
