weight less on moon than on earth.
high on lift off - G force
low in orbit.
zero at a point between earth and moon
Answer:
c)From high potential to low potential.
Explanation:
Given that
current is flowing through resister.
As we know that those quantity have direction as well as magnitude then these are called vector quantity and those quantity have only magnitude then they called scalar quantity.
As we know that current have direction as well as magnitude so current is a vector quantity.
Current flows from high potential to low potential.
The SI unit of force is the Newton.
1 newton is the force that accelerates a 1 kilogram mass
at the rate of 1 meter per second².
1 pound of force is equivalent to roughly 4.448 newtons.
(1 newton is equivalent to roughly 0.225 pounds of force.)
Answer:
why did the parents let go of their child-
Explanation:
A 5 kg, because 90 / 18 is 5
Answer:
is reflected back into the region of higher index
Explanation:
Total internal reflection is a phenomenon that occurs when all the light passing from a region of higher index of refraction to a region of lower index is reflected back into the region of higher index.
According to Snell's law, refraction of ligth is described by the equation

where
n1 is the refractive index of the first medium
n2 is the refractive index of the second medium
is the angle of incidence (in the first medium)
is the angle of refraction (in the second medium)
Let's now consider a situation in which

so light is moving from a medium with higher index to a medium with lower index. We can re-write the equation as

Where
is a number greater than 1. This means that above a certain value of the angle of incidence
, the term on the right can become greater than 1. So this would mean

But this is not possible (the sine cannot be larger than 1), so no refraction occurs in this case, and all the light is reflected back into the initial medium (total internal reflection). The value of the angle of incidence above which this phenomen occurs is called critical angle, and it is given by
