Answer:
α = - 1.883 rev/min²
Explanation:
Given
ωin = 113 rev/min
ωfin = 0 rev/min
t = 1.0 h = 60 min
α = ?
we can use the following equation
ωfin = ωin + α*t ⇒ α = (ωfin - ωin) / t
⇒ α = (0 rev/min - 113 rev/min) / (60 min)
⇒ α = - 1.883 rev/min²
F = ma so u can plug in the given numbers and solve:
F = (2)(3)
I believe that the price will rise.
Hope this helps!
Protons
Explanation:
In a neutral atom, the number of electrons equals the number of protons in the atom.
- Electrons are the negatively charge particles in an atom
- Protons carry positive charge.
- Neutrons do not carry any charges.
Protons and neutrons are contained in the nucleus of an atom they determine the mass number of the atom.
In a neutral atom, the number of protons and electrons must be the same.
A charge atom called an ion is one that has lost or gained electrons.
