An atom in an excited state has higher energy and is less stable than the atom in the ground state.
I hope this helps!
Explanation:
Given that,
The kinetic energy of the electron,
Radius of the orbit, r = 37.4 cm = 0.374 m
To find,
(a) the electron's speed, (b) the magnetic field magnitude, (c) the circling frequency, and (d) the period of the motion.
Solve,
We know that,
(a) The formula of the kinetic energy is given by :
v is the speed if electron
m is the mass of electron
(b) Let B is the magnitude of magnetic field. On the circular path the magnetic field is given by :
(c) Let T is the time period of the motion. It is given by :
Circling frequency is given by :
(d) The period of motion,
Answer:
The correct answer to the question is
Both A and B are true
Explanation:
The particles of a gas are free to move to occupy the entire volume in which they are placed due to the smallerinter molecular forces holding them together hence due to the face that pressure is a measure of the Force per unit area that is Pressure P = ( Force F)/ (Area A) then the force per unit area, exerted on the all of the container by the gaseous particles which are colliding with each other and with the walss of the container is fairly constant through out the surface oof the container
In the case of the liquid which are held on together by more stronger forces, the force per nit area exerted by the liquid particle is transmitted from one particle to the next until it reaches the container's surface. Then remembering that the force of gravity on the liquid is acting in one direction (that is downwards) the sum of the fprce due to the weight incrreases as we progress deaper into the liquid hence the pressure increases per unit depth
Answer:
<h3>The answer is 6000 N</h3>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 3000 × 2
We have the final answer as
<h3>6000 N</h3>
