Answer: Mercury<Uranus<Earth<Neptune
Explanation: Weight is the downward force acting on an object due to gravity.
w= weight of an object
m= mass of object
g= gravity
As the person has a constant mass, the weight differs due to the value of gravity (g). The planet having highest gravity would make a person weigh the most.
As the value of gravity varies: Mercury (3.7)<Uranus(8.9)<Earth(9.8)<neptune(11.2), the weight of the person varies in the same order: Mercury<Uranus<Earth<neptune.

Answer:
Mirages happen when the ground is very hot and the air is cool.
Explanation:
They happen when light passes through two layers of air with different temperatures. The desert sun heats the sand, which in turn heats the air just above it. The hot air bends light rays and reflects the sky.
When you see it from a distance, the different air masses colliding with each other act as a mirror.
