Answer:

The reason for the increase or decrease of the moon is <u>due to the angular perception of the moon. </u>

Explanation:

Also called lunar illusion, this phenomenon is due to the position in which the moon is, it can be at the zenith or on the horizon, both distances are different from each other with respect to the position of the person.

The zenith is the highest part of the sky and the horizon the lowest.

When there are landmarks such as trees, buildings or mountains on the horizon, the illusion of closeness is given and the illusion of distance is misinterpreted.

But when looking up at the sky as there is no reference point there will be a failure in the perception of size.

Jobisdone [24]

Answer:

The correct option is;

Technician A

Explanation:

Here we note failure analysis will assist in determining the cause of failure and as such to determine the cost effectiveness of a repair or a replacement.

However, a warranty is a legal contract between the buyer of the engine and the manufacturer for the manufacturer to either repair the engine or compensate the the customer for all failures that occur within the period of the warranty. Therefore, technician B is not correct as he says the manufacturer may request the engine for analysis on why it failed which is not the same as the basis of a warranty.

6. Mithra is an unknown planet that has two airless moons. A and B, in circular orbits around it.

The acceleration of gravity on Moon B is D) 0.25 m/s2

Explanation:

The data listed in the problem are not clear: find them in the table attached.

The acceleration of gravity on a planet is given by the following equation:

$g=\frac{GM}{R^2}$

where:

$G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2}$ is the gravitational constant

M is the mass of the planet

R is the radius of the planet

Here we want to find the acceleration of gravity on the surface of Moon B, which has the following data:

$M=1.5\cdot 10^{20} kg$ (mass)

$R=2.0\cdot 10^5 m$ (radius)

And substituting into the equation, we find:

$g=\frac{(6.67\cdot 10^{-11})(1.5\cdot 10^{20})}{(2.0\cdot 10^5)^2}=0.25 m/s^2$

You have given a power supply, copper wire, and an iron nail. What should you do to decrease the strength of the electro magnet?

Viefleur [7K]

Explanation:

If you wrap some of the wire around the nail in one direction and some of the wire in the other direction, the magnetic fields from the different sections fight each other and cancel out, reducing the strength of your magnet
