Answer:
2.56 N*m
Explanation:
Torque is force times distance, with the force being perpendicular to the distance.
If the force and distance are not perpendicular, a projection of one of the two must be used instead.
We will use the projection of the length of the shaft upon a perpendicular of the force applied. This will have a magnitude of:
Lh = L * cos(a) (I name it Lh because it is a horizontal projection in this case)
Lh = 0.2 * cos(π/5) = 0.16 m
Then:
T = f * d
T = 16 * 0.16 = 2.56 N*m
Before coming into conclusion first we have to understand both scalar and vector .
A scalar quantity is a physical quantity which has only magnitude for it's complete specification.
A vector quantity is that physical quantity which not only requires magnitude but also possesses direction for it's complete specification.
So the most important factor that differentiate vector from scalar is the direction.
As per the question the student is doing an experiment where he is recording the data obtained during the process.
In order to arrange them in data table, he should ask about the direction of the quantity under consideration.
Hence the correct option is the third option(C)i.e does the measurement include direction?
Increasing ambient temperature decreases efficiency and load carrying capacity of electric transmission lines.
Increased molecular movement in the conductors as temperature rises, increases resistance to current flow.

Answer:
The number take for the "radius" is normally taken to be the radius from the center to the event horizon, since nothing inside that can be observed, and since it is a point of no return. This radius is directly proportional to the mass of the black hole. From the Wikipedia article on event horizon: "For the mass of the Sun this radius is approximately 3 kilometers and for the Earth it is about 9 millimeters. In practice, however, neither the Earth nor the Sun has the necessary mass and therefore the necessary gravitational force, to overcome electron and neutron degeneracy pressure." The last sentence means that it is unlikely for the Sun to become a black hole, since it has too little mass to become one.
