Answer:
80 meters high
Explanation:
The velocity of the balloon would be g*t (I won't calculate, but will us this later)
We know that the kinetic energy at the bottom equals the potential at the top.
KE = PE
1/2 * m * v^2 = m * g * h
1/2 * m * (g * t)^2 = m * g * h (substitution)
1/2 * m * g^2 * t^2 = m * g * h
1/2 * g * t^2 = h (simplification by dividing the commons between both sides)
h = 1/2 * 9.81 * 4^2
h = 78.48 m (roughly 80 m)
B, larceny because that's theft of personal property.
Yes because if 0*c equals 32*F than the higher the number the hotter it is
Answer:
A
Explanation:
Did on a quiz and got it right
Since the diameter of helium atom is approximately 
, therefore the diameter of helium atom in nano meter,
