The angle of reflection is the angle between the reflected ray and the normal.
In this case the angle of reflection is 42 degrees
Characteristics of images formed in a plane mirror include
The image is upright
The image is virtual
the image is the same size as the object
The image is at the same distance from the mirror as the object
The image is formed behind the mirror
A plane mirror forms an image which is the same size as the object
Therefore since the object is 26 cm long , the image would still be 26 cm.
Answer:
The angular distance in revolution is 
The angular distance in radians is 
The angular distance in degrees is 
The angular size is 
Explanation:
From the question we are told that
The diameter is 
The distance moved by the rim is 
Generally the circumference of the pie plate is mathematically represented as
Substituting the values
The number resolution carried out by the pie plate is evaluated as
Substituting value
The angular distance 
is mathematically evaluated as
Where r is the radius which is mathematically evaluated as
Substituting this into the equation for angular distance
The angular distance traveled in degrees is
When the pie is cut into 9 equal parts
The angular size would be mathematically evaluated as
The total charge that passes through an electrolytic cell is given by the product of current and time.
An electrolytic cell is an electrochemical cell that utilizes an external source of electrical energy (voltage applied between two electrodes) to drive a chemical reaction that would not otherwise occur. This is in contrast to a galvanic cell, which itself is a source of electrical energy and the foundation of a battery.
The net reaction taking place in a galvanic cell is a spontaneous reaction, i.e. the Gibbs free energy remains negative, while the net reaction taking place in an electrolytic cell is the reverse of this spontaneous reaction, i.e. the Gibbs free energy is positive.
An electrolytic cell has three components: an electrolyte and two electrodes (a cathode and an anode). The electrolyte is usually a solution of water or other solvents in which ions are dissolved.
Molten salts such as sodium chloride can also function as electrolytes. When driven by an external voltage applied to the electrodes, the ions in the electrolyte are attracted to an electrode with the opposite charge, where charge-transferring (also called faradaic or redox) reactions can take place.
Only with an external electrical potential (i.e., voltage) of correct polarity and sufficient magnitude can an electrolytic cell decompose a normally stable, or inert chemical compound in the solution. The electrical energy provided can produce a chemical reaction which would not otherwise occur spontaneously.

Processes in which matter changes between liquid and gaseous states are vaporization, evaporation, and condensation.
Answer: 
Explanation:
The rest of the question is below:
Find a2, the magnitude of the centripetal acceleration of the star with mass m2.
Assuming both stars are describing a uniform circular motion, their acceleration vector is directed towards the center of mass of the system (that's why it's called centripetal acceleration).
Now, according to Newton's 2nd law, the force 
is directly proportional and in the same direction as the acceleration.
For 
:
For 
:
If the centripetal force is the same for both stars:
Isolating
