The formula for centripetal acceleration is v^2/r, where v is the tangential velocity, and r is the radius.
<span>Alternatively, w^2r where w is the angular velocity and r is the radius.
</span><span>The centripetal acceleration is ar=(((1.70 rev/s)*(2*pi rad/rev))^2)*(0.132m)= 15.06 m/s^2 </span>
Answer:
-D) Identify a question, make observations, create a hypothesis, and then set up an experiment to test the hypothesis because need to follow the steps to do the experiment properly.
Answer:
counterclockwise
Explanation:
given data
area = 25 cm²
solution
We know that a changing magnetic field induces the current and induced emf is express as
..................................1
and we will get here direction of the induced current in the loop that is express by the Lens law that state that the direction of induces current is such that the magnetic flux due to the induced current opposes the change in magnetic flux due to the change in magnetic field
so when magnetic field decrease and point coming out of the paper.
so induced current in the loop will be counterclockwise
Answer:
More force
Explanation:
Object A has more mass than object B
For object A to accelerate at the same rate as object B, it will need more force.
According to Newton's second law of motion "the net force on a body is the product of its mass and acceleration".
Net force = mass x acceleration
Now, if a body has more mass and needs to accelerate at the same rate as another one with a lower mass, the force on it must be increased.
Skeletal muscles must have help from the bone to be able to move.
