Answer:
271248.75 N
Explanation:
= Density of air = 1.14 kg/m³
v = Velocity of wind = 45 m/s
A = Area = 235 m²
From Bernoulli's principle we have the relation
Force is given by
Force due to the jet stream on the roof is 271248.75 N
Answer: false because normally the equinox would mark the longest days of the year
Answer/Explanation:
The highest point of potential energy is A, when the ball rolls down the hill potential energy decreases and kinetic energy decreases, but the total energy is constant no matter what. This means the energy does not go away but instead is transferred to a different form.
A: most potential and least kinetic
B: losing potential gaining kinetic
C: losing more potential and gaining more kinetic
D: most kinetic and least potential
E: Gaining potential and losing kinetic
F: Gaining more potential and losing more kinetic
G: more potential than kinetic but not the most potential

Electrons are negatively charged particles whereas protons are positively charged particles.
When a negative is shown on the bar, this means that the difference between the electrons and protons is a negative value, which also means that the number of electrons (negative particles) is more than the number of protons (positive particles).
Based on the above, the correct choice would be:
<span>D. There are more electrons than protons
