The number of protons in one atom of an element determines the atom’s identity and the number of electrons determines electrical charge of an element.
<u>Explanation:
</u>
Atoms are made up of protons, neutrons and electrons. The protons and neutrons are enclosed in a specific spherical region at the center of the atom termed as nucleus of the atom. This is because proton is positive charge and neutron is neutral charged high mass particles.
While the electrons are negative charged lighter mass particles. So the electrons will revolve around the nucleus. The protons number in element's one atom helps to identity its chemical properties of the element. While the electrons number in an element will determine the electrical charge and conducting nature of the element.
Recall that given the velocity and wavelength, frequency can be computed as
Substituting the given values, we have
Answer: 477 Hz
The specific heat of the metal is 
Explanation:
When a sample of a material absorbs energy, its temperature increases according to the equation
where
Q is the amount of energy supplied to the sample
m is the mass of the sample
Cs is its specific heat capacity
is the increase in temperature
In this problem,
m = 50.0 g
Q = 220.0 J
Solving for C_s, we find the specific heat capacity:

Answer:
Explanation:
initial velocity, u = 0
final velocity, v = 18 m/s
time = 20 sec
acceleration, a = v - u / t
= 18 - 0 / 20
= 18 / 20
= 9 / 10
= 0.9 m/s^2
