What would be the mass of a coin of double thickness if the density remains the same?
If the density AND the diameter are the same, then the coin with double thickness has double the mass.
What type of reflection reflects off a smooth surface?
its the very normal reflection in which the angle of i and r are the same
What is the size of the angle of incidence and reflection?
Angle of incidence can be anything. Angle of reflection is the same as angle of incidence.
What is the definition for reflection in the field of physics?
the return of light into the same medium after striking a surface is called reflection. ruchi
Can reflection and refraction happen at the same time?
yes
What one transformation is the same as a reflection over two parallel lines?
A translation.
What transformation gives the same result as a rotation of 180 around the origin followed by a reflection over the x axis?
Reflection in the y-axis.
What transformation is equivalent to reflection over a point geometry?
Reflection over a point is equivalent to enlargement with the same point as the focus of enlargement and a scale factor of -1.
Which transformation is not a rigid transformation?
A rigid transformation means it has the same size and shape so it would be a dilation
Complete this sentence after a congruence transformation the area of a triangle would be it was before?
This sentence can be complete as: After a congruence transformation the area of a triangle would be the same as it was before.
Is a transformation the same as an isometric transformation?
No it is not.
What reflection would you get from black hat in a red room?
the same what it looks like. DA!
What is the rule for a reflection across the x-axis?
For a reflection across the x axis, both the slope and the y intercept would have the same magnitude but the opposite sign.
What is the angle of reflection if the angle between the incident ray and reflected ray is 140 degrees?
The angle of reflection is 140/2 = 70 degrees. The angle of reflection is the same as the the same as the incident.
What would be the mass of a coin of double thickness if the density remains the same?
If the density AND the diameter are the same, then the coin with double thickness has double the mass.
How do you determine invariant points of a graph algebraically?
Invariants are points that remain the same under certain transformations. You could plug the points into your transformation and note that what does in is the same as what comes out. The details depend on the transformation.
Why are chemical and physical changes the same?
They're not the same. They're not the same.
