Explanation:
It is given that,
Mass, 
Acceleration due to gravity, 
Acceleration due to gravity is given by :
r = distance from head
r = 1.42 m
So, at the distance of 1.42 meters from the head its gravitational pull on you match that of Earth's. Hence, this is the required solution.
Well , i think helium gas is present in the Earth Crust because metals found in the crust have nuclei that decay into another elements
One of this element that formed is Helium
hope this helps
Answer:
c. -14,000
Explanation:
Workdone by gas is the product of the pressure and the volume where there is a change of volume.
If v1 is the initial volume of the gas and v2 is the final volume of gas, the work done
= p(v2 - v1)
where p is the pressure
and p = 70,000 Pa
Given that volume decrease by 0.2m^3, v2 - v1 = -0.2
Workdone = 70000 ( -0.2)
Workdone = -14,000 J
Option c. -14,000
Explanation:
you can see this example to undersranding the question
Answer:
the SI unit of momentum is :- kg.ms-1
and we know that,
kinetic energy = 1/2 mv2
E=p2/2m
p=(2Em)1/2
so the derived units are (J.kg)1/2
