Explanation:
We have,
Electric field intensity is 700 N/Cj
It is required to find the magnitude and direction of the acceleration of this electron due to this field.
The electric force is balanced by the force due to its motion i.e.
qE =ma
a is acceleration of this electron
So, the acceleration of the electron is and it is moving in +y direction.
Answer:
Energy of scattered photon is 232.27 keV.
Kinetic energy of recoil electron is 497.73 keV.
The recoil angle of electron is 13.40°
Explanation:
The energy of scattered photon is given by the relation :
.....(1)
Here E₁ is the energy of incident photon, E₂ is the energy of scattered photon, is mass of electron and θ is scattered angle.
Substitute 730 keV for E₁, 511 keV for and 120° for θ in equation (1).
E₂ = 232.27 keV
Kinetic energy of recoil electron is given by the relation :
K.E. = E₁ - E₂ = (730 - 232.27 ) keV = 497.73 keV
The recoil angle of electron is given by :
Substitute the suitable values in above equation.
= 13.40°
Answer:
B)154 J
Explanation:
Mass of bowling ball=m=6.55kg
Height of bowling ball from ground=h=2.4m
Acceleration due to gravity=
We know that
Potential energy=mgh
Where m=Mass of object
g=Acceleration due to gravity
h=Height of object from ground
Substitute the values then we get
Potential energy=
Hence, the increase in the ball's potential energy=154J
The cochlea is the organ responsible for <em>hearing</em>, and it is composed of several interconnected structures through which a pressure wave passes. Beginning at <u>the oval window</u>, the pressure wave then moves through:
- Scala vestibuli
- Reissner's membrane
- Scala tympani
- Basilar membrane
And finally exits through the round window.
<h3>Order the structures that a pressure wave passes through in the cochlea:</h3>
- Oval window
- Scala vestibuli
- Reissner's membrane
- Scala tympani
- Basilar membrane
- Round window
This chain of structures creates a <em>pathway </em>that allows the pressure wave to pass through <u>the cochlea</u>, converting sound waves into signals that are then sent to the brain and interpreted as sound.
