#1
As per kinematics we know that
here we know that
now we will have
Now by Newton's II law
#2
part a)
Impulse = change in momentum
given that
m = 0.153 kg
v = 25.7 m/s
now we have
Part b)
As per Newton's II law we know that
as we know that
The units of pressure are called derived units because it is derived from base unit, which is distance and a derived unit which is force. Force is derived from acceleration, a derived unit as well, and mass, a base unit; which makes it a derived unit.
It uses microwaves as little heatwaves and uses them to heat the food
Answer:
Valence electrons are the electrons present in the outermost shell of an atom. You can easily determine the number of valence electrons an atom can have by looking at its Group in the periodic table.
