A. The slope represents the rate of increase in elevation in feet per minute.
b. The elevation is increasing with time so we are hiking uphill.
The atom is neutral (no electric charge)
Explanation:
An atom consists of:
- A nucleus, containing protons (positively charged) and neutrons (no electric charge)
- Electrons (negatively charged), orbiting around the nucleus
The charge of one proton is equal in magnitude (but opposite in sign) to that of an electron, and it is
Moreover, for a normal atom, the number of protons in the nucleus is equal to the number of electrons around it.
This means that for a normal atom, the net charge of it is zero, since the total charge of the protons balance that of the electrons.
So, the answer to the question is that the atom is neutral.

<span>In the vertical direction
there is no change of momentum.
Momentum in vertical = 1.5 * 9 = 13.5
Speed in vertical = 9 m/s
Momentum of Raven in x + momentum of falcon = initial momentum in x
=> Mx + 600*5 = 600*20
=> Mx = 600*15
=> Vx = 6000
Vy = 9
=> tanθ = 0.6 kg/9 = 0.066667</span>

We will apply the equation:
2as = v² - u²
v = √(2as + u²)
v = √(2 x 4 x 400 + 13²)
v = 58 m/s
hope this helps
