Since the two colliding objects travel together in the same direction after the collision, the total momentum is simply the total mass of the objects multiplied by their velocity
It is C because less than one percent of water is fresh water
Answer: 20 pm=20*10^-12 m
Explanation: To solve this problem we have to use the relationship given by:
λmin=h*c/e*ΔV= 1240/60000 eV=20 pm
this expression is related with the bremsstrahlung radiation when a flux of energetic electrons are strongly stopped hitting to a catode. The electrons give their kinetic energy to the atoms of the catode.
Answer:
orbital period increased by a factor of 2.83 unit
Explanation:
Given.
planet’s orbital period, T, and the planets mean distance from the sun, A, in astronomical units, AU
T²= A³
If A is increased by a factor of 2 , .
Then T will be increase with the factor of √2³ = 2.83
