All 50 states have a 21 year old minimum drinking age according to the national drinking age act of 1984.
Answer:
441J
Explanation:
Given parameters:
Mass of book = 5kg
Height = 9m
Unknown:
Gravitational potential energy = ?
Solution:
The gravitational potential energy of a body is the energy due to the position of the body.
It is given as:
Gravitational potential energy = mass x acceleration due to gravity x height
Gravitational potential energy = 5 x 9.8 x 9 = 441J
<span>Kirchhoff's voltage law has nothing to do with gain or loss of energy by electronic components (resistors, capacitors, etc.). It is a law referring to the potential field generated by voltage sources. In this potential field, regardless of what electronic components are present, the gain or loss in "energy given by the potential field" must be zero when a charge completes a closed loop.</span>
The equation relevant to use here is:
v^2 = v0^2 + 2 a d
where,
v is final velocity = ?
v0 is intial velocity = 193.8 m/s
a is acceleration = 13.5 m/s^2
d is distance = 2370 m
v = sqrt [193.8^2 + 2 (13.5) 2370]
v = 318.67 m/s
