A dumbbell-shaped object is composed by two equal masses, m, connected by a rod of negligible mass and length r. If I_1 is the m
1 answer:
Answer:
I2>I1
Explanation:
This problem can be solved by using the parallel axis theorem. If the axis of rotation of a rigid body (with moment of inertia I1 at its center of mass) is changed, then, the new moment of inertia is gven by:
where M is the mass of the object and d is the distance of the new axis to the axis of the center of mass.
It is clear that I2 is greater than I1 by the contribution of the term Md^2.
I2>I1

Part b)
Explanation:
Part a)
Electric field due to large sheet is given as
now the electric field is given as
Now acceleration of an electron due to this electric field is given as
Now work done on the electron due to this electric field
So work done is given as
Part b)
Now we know that work done by all forces = change in kinetic energy of the electron
so we will have
Answer:
d = (3 i + 5 j) 3 [m] x-distance and 5 [m] y-distance
Explanation:
We can find the displacement if we use a diagram with the cartesian coordinates of the displacement of the mouse.
In the attached image we can see each of the vectors and the origin where the mouse was in the initial position and then the final position after the mouse moved to the right.
So the mouse moved 3 meters to the right and 5 meter upward.
