Calculate the energy found in one photon of visible light if the wavelength is 589 nm.
1 answer:
The energy found in one photon of visible light if the wavelength is 589 nm is, 3.37*10^-19J.
To find the answer, we have to know more about the energy of photon.
<h3>What is the energy of photon?</h3>- We have the expression of energy of photon as,
where, c is the speed of light and h is the plank's constant.
- It is given in question that, the wavelength is 589 nm.
- Thus, the energy will be,
Thus, we can conclude that, the energy found in one photon of visible light if the wavelength is 589 nm is 3.37*10^-19J.

The magnitude of the downward acceleration of the hollow cylinder is 6m/s^2.
Z = I α
T.R =1/2 M ( +
)α
T.R = 1/2M 5/4 α
T = 5Ma/8
Mg - T = Ma
Mg - 5Ma/8 = Ma
Mg= 5Ma/8 + Ma = 13Ma / 8
acceleration = 8g/13 = 6 m/s^2
The rate at which an object's velocity with respect to time changes is called its acceleration. The direction of the net force imposed on an item determines its acceleration in relation to that force. According to Newton's Second Law, the magnitude of an object's acceleration is the result of two factors working together
The size of the net balance of all external forces acting on that item is directly proportional to the magnitude of this net resultant force; the magnitude of that object's mass, depending on the materials from which it is built, is inversely related to its mass.

Answer:
1.6 x N
Explanation:
If the force between two actual wires has this value, the current is defined to be exactly 1 A.
The force between two parallel wires carrying current can be defined as,
F= μ
L/ 2πd
where,
current = 1Amp
current = 2amp
Length 'L'= 1m
distance 'd'= 2.5m
permeability of free space 'μ'= 4πx N/m
Putting the above values in the equation,
F=( 4πx x 1 x 2 x 1 )/ 2πx2.5
F= 1.6 x N
