Explanation:
A process by which water moves from Earth's surface into the sky and back again
hey there!
atomic mass cobalt = 58.9332 amu
therefore:
1 mol Co ------------ 58.9332 g
moles ------------ 50 g
moles = 50 x 1 / 58.9332
moles = 50 / 58.9332
= 0.8484 moles of Co
Hope this helps!
When placed inside of a magnetic field, the magnetic field that electrons generate aligns in the opposite direction of the applied magnetic field.
Also, someone who is very popular and attracts people has a charming personality. A powerful speaker that attracts many fans has an engaging way of speaking. A magnetic person is attracted to you as if by a magical magnetism. Both meanings of magnetic have to do with the force of attraction. Only ferromagnetic materials such as iron, cobalt and nickel are attracted to magnetic fields strong enough to be considered truly magnetic.
All magnetic fields contain energy, also called magnetic energy. In physics, it is a constant. Magnetic energy is a form of energy from moving charge carriers (electrons) because magnetic fields are generated by electric currents.

We can assume that all<span> gravitational potential energy is converted into
kinetic energy of the object.</span><span>
<span>Hence, </span>GPE = KE
Where GPE is gravitational Potential Energy (J)
and KE is Kinetic Energy (J)
GPE = mgh
<span>Where, m is the mass of the object (kg), g is acceleration due to gravity (9.8 m s</span></span>⁻<span>²) and h is the height to the<span> object from ground (m).</span></span><span>
m = 0.18 kg
g = 9.8 m s</span>⁻²<span>
h = 45 m
Hence,
GPE = 0.18 kg x 9.8 m s</span>⁻² x 45 m<span>
= 79.38 J
≈ 79 J
<span>Hence, </span>KE = GPE = 79 J
<span>Hence, the
answer is '79 joules'.</span></span>
