If 0.25mg of atropine is in 1mL
so
0.50mg of atropine is in x
Answer:
1.99 x 10⁻¹⁸J
Explanation:
Given parameters:
Frequency of the wave = 3 x 10¹⁵Hz
Unknown:
Energy of the photon = ?
Solution:
To solve this problem, we use the expression below;
E = hf
Where E is the energy, h is the Planck's constant and f is the frequency
Now insert the parameters and solve for E;
E = 6.63 x 10⁻³⁴ x 3 x 10¹⁵ = 19.9 x 10⁻¹⁹J or 1.99 x 10⁻¹⁸J
Gravitational force is much weaker, because it is the force of gravity, or the force that makes smaller objects be pulled towards a much bigger one with a certain amount of force.
Now strong nuclear force, which is very strong, keeps the atomic particles in an atom from separating, and the reason it is so powerful is because the particles in an atom repel each other and this force keeps them from doing .that
Fossil Fuels give off energy when they are burned
One valuable fossil fuel is natural gas. It is a cleaner-burning fuel source.
Uranium emits particles and rays spontaneously through this process called radioactive decay or radioactivity.
Is the process by which the nucleus of an unstable atom loses energy by emitting radiation, including alpha particles, beta particles. gamma rays and conversion electrons.
