Answer:The angle between the refracted ray and the normal.</h2>
Explanation:
Refraction is defined as the phenomenon of bending or changing course of a light ray when it passes from one medium to another medium.
The new ray formed after the bending at the surface of new medium is called the refracted ray.
The angle between the refracted ray and the normal of the point on the surface of the new medium where the ray enters is called angle of refraction.
Refer the attachment for instance.
In short,it is the angle between the refracted ray and the normal.
Answer:
The third charge placed is 0.80 m.
Explanation:
Given that,
Distance = 0.57 m
First charge = q
Third charge = 2q
We need to calculate the electrostatic force on charge q₁ due to q₂
Using formula of electrostatic force
When placed another charge q₃ at certain distance from origin, then the net force on charge q₁ due to both charges is
The net electrostatic force on the charge at the origin doubles.
Put the value into the formula
Hence, The third charge placed is 0.80 m from origin in x-axis.
You have several electrical units listed there:
a). C often used to represent a Capacitance.
b). 'A' often represents 'Ampere', the unit of Current.
c). 'R' often used to represent a Resistance.
d). 'E' often used to represent a Voltage (Electromotive Force).
Not to mention ' A. C ', a whimsical offering,
reminiscent of 'Alternating Current'.
The tension in the string when the ball is at the bottom of the path is 2.61 Newtons.
<h3>Tension</h3>
A tension is simply referred to as a force along the length of a flexible medium such as strings, cable, ropes etc.
Tension in a string revolving can be determined using the expression;
T = mv² / r
Where m is mass of object, v is velocity and r is radius ( length of string )
Given the data in the question;
- Radius ( length of string ) r = 97.7cm = 0.977m
- Tension in the string; T = ?
To determine tension in the string, we substitute our given values into the expression above.
T = mv² / r
T = (0.182kg × (3.74m/s)²) / 0.977m
T = (0.182kg × 13.9876m²/s²) / 0.977m
T = (2.5457432kgm²/s²) / 0.977m
T = 2.61kgm/s²
T = 2.61N
Therefore, the tension in the string when the ball is at the bottom of the path is 2.61 Newtons.
