Answer:

The answer is Radiation.

Explanation:

The phenomenon of radiation is the propagation of energy in the form of electromagnetic waves or subatomic particles through vacuum or a material medium. Solar radiation is the set of electromagnetic radiation emitted by the Sun and which reach the earth, although not all radiation reaches the Earth's surface, because the shortest ultraviolet waves are absorbed by the gases of the atmosphere. The magnitude that measures the solar radiation that reaches the Earth is the irradiance, which measures the power that per unit of surface reaches the Earth.

The vector product of vectors A⃗ and B⃗ has magnitude 12.0 m2 and is in the +z-direction.Vector A⃗ has magnitude 4.0 m and is in
g100num [7]

Answer:

θ=180°

Explanation:

The problem says that the vector product of A and B is in the +z-direction, and that the vector A is in the -x-direction. Since vector B has no x-component, and is perpendicular to the z-axis (as A and B are both perpendicular to their vector product), vector B has to be in the y-axis.

Using the right hand rule for vector product, we can test the two possible cases:

  • If vector B is in the +y-axis, the product AxB should be in the -z-axis. Since it is in the +z-axis, this is not correct.

  • If vector B is in the -y-axis, the product AxB should be in the +z-axis. This is the correct option.

Now, the problem says that the angle θ is measured from the +y-direction to the +z-direction. This means that the -y-direction has an angle of 180° (half turn).

Question 8
Viefleur [7K]

Answer:

96 Joules

Explanation:

The formula for work is Fnet times displacement (F x d = w) which, in this case, 48N is the Fnet and 2m as the displacement. Then all we need to do is multiply these two and we get 96 Joules.
