Answer:
the average kinetic energy of water particles - C.
I just did this last semester... I know this is wave height!!
Answer: option B
Explanation: when a neutral atom loses an electron or gains a positive charge electron, it becomes a positive ion (positively charged) and when an neutral atom gains an electronic charge or losses a positive charge electron, it becomes a negative ion (negatively charged).
Answer:
a
b
Explanation:
From the question we are told that
The mass of the person is
The speed of the person is
The energy of the proton is
Generally the de Broglie wavelength is mathematically represented as
Here h is the Planck constant with the value
So
=>
Generally the energy of the proton is mathematically represented as
Here is the mass of proton with value
=>
=>
=>
So
so
=>
Answer:
Increasing its charge
Increasing the field strength
Explanation:
For a charged particle moving in a circular path in a uniform magnetic field, the centripetal force is provided by the magnetic force, so we can write:
where
q is the charge
v is the velocity
B is the magnetic field
m is the mass
r is the radius of the orbit
The period of the motion is
Re-arranging for r
And substituting into the previous equation
Solving for T,
So we see that the period is:
- proportional to the charge and the magnetic field
- inversely proportional to the mass and the square of the speed
So the following will increase the period of the particle's motion:
Increasing its charge
Increasing the field strength
