Answer:
Image is twice as large as the object, and inverted
Explanation:
When an object is placed in front of a mirror, the mirror produces an image.
The magnification of the image is a number telling how much the size of the image is enlarged/diminished with respect to the object.
It is given by
where
M is the magnification
y' is the size of the image
y is the size of the object
In this problem,
M = -2
This means that:
So, we can conclude the following:
- The size of the image is twice the size of the real object
- The image is also inverted, because of the presence of the negative sign in the equation
Answer:
Explanation:
Given
Volume of fixed chamber
Initial Temperature
Final Temperature
Heat Supplied
From First law of thermodynamics
Change in internal energy of the system is equal to heat added minus work done by the system
as the volume is fixed therefore work
thus
for mono-atomic gas is
and 1 mole contains
thus No of molecules
No of molecules
Answer:
Explanation:
m = Masa del coche
g = Aceleración debida a la gravedad =
h = Altura =
v = Velocidad del automóvil en la parte inferior de la pista
Aquí asumimos que el automóvil desciende verticalmente. La energía potencial del automóvil se completará convertida en energía cinética en la parte inferior de la pista ya que no hay pérdida de energía.
La velocidad máxima que puede alcanzar el coche es .
