Answer:
The Right Hand Rule, illustrated at left, simply shows how a current-carrying wire generates a magnetic field. ... The Left Hand Rule shows what happens when an electrical current enters a magnetic field. You need to contort your hand in an unnatural position for this rule, illustrated below
Answer:
The time interval is
Explanation:
From the question we are told that
The angular acceleration is
The time taken is
The angular displacement is
The angular displacement can be represented by the second equation of motion as shown below
where is the initial velocity at the start of the 4 second interval
So substituting values
=>
Now considering this motion starting from the start point (that is rest ) we have
Where is the angular velocity at rest which is zero and is the angular velocity after 4.0 second which is calculated as 12 rad/s s
=>
A silver spoon (B.) A silver spoon is metal so it would be the best answer out of the four. a rubber tire is a good insulator but not a good conductor. Thank you!
Answer:
9.8m/s^2 down (option C)
Explanation:
The only acceleration acting on this motion case in the acceleration due to gravity: 9.8 m/s^2 in the downwards direction.
