4 gamma closest thing to this V
Explanation:
Technetium. Tc is a very versatile radioisotope, and is the most commonly used radioisotope tracer in medicine.
Non living and dead are the same thing
It takes 392 joules of work to lift it.
It has 392 joules of gravitational potential energy up there.
Answer:
1. The standard metric unit of momentum is the kg•m/s.
2. the units of momentum will be the product of the units of mass and velocity. Mass is measured in kg and velocity in ms-1, therefore, the SI unit of momentum will be kgm/s(-1).
3.Recall that acceleration is rate of change of velocity, so we can rewrite the Second Law: force = mass x rate of change of velocity. Now, the momentum is mv, mass x velocity. ... rate of change of momentum = mass x rate of change of velocity.
Explanation:
i really hope i helped sorry for the paragraphs ;( !
Answer:
The velocity is 
Explanation:
From the question we are told that
The speed of the roller coaster at ground level is 
Generally we can define the roller coaster speed at ground level using the an equation of motion as

u is zero given that the roller coaster started from rest
So

So

=> 
Now the displacement half way is mathematically represented as


So

Where
is the velocity at the half way point
=> 
=>
