Answer:
At the focus
Explanation:
In car head lights concave mirrors are used. The light bulbs in these headlights are place along the principal axis as shown in the figure. On this Principal axis light bulbs are place at the Focus to get maximum brightness. As from the figure we can conclude that light rays coming from infinity converse at focus thus, giving maximum brightness.
Answer:
That is true, the hotter a star is the shorter of wavelength it emits and the higher. It also depends on the mass of the star because the bigger it is, the faster it fuses its hydrogen fuel. Faster burning of fuel means more energy is released and so results in higher temperatures.
Hope this helps! Good luck :)

Answer:
If force is applied to cause the motion of the body
Explanation:
In the setup given in this diagram, potential energy can be converted into kinetic energy by applying force on the cart or object to move it down the slope.
Potential energy is the energy due to the position of a body. The body has huge potential energy at its current position.
Kinetic energy is the energy due to the motion of a body.
As the body moves down the slope and its velocity increases, it gains massive kinetic energy.
Down the slope, the kinetic energy increases as the potential energy decreases.
At the bottom of the slope, the potential energy becomes zero and the kinetic energy is at its maximum.
Since it is specified that the relationship is linear, you could think of a linear graph for this. The base year would be 1994. The first point is at (0,2523) while the second point is (2,2891). The slope would be
m = (2891 - 2523)/(2-0) = 184
The slope-intercept form is y = mx + b. Let's substitute (0,2523) to the equation such that
2523 = 184(0)+b
b = 2523
Hence, the equation of the linear graph is y = 184x + 2523. Now, at 2006, x = 2006 - 1994 = 12 years.
y = 184(12) + 2523 = 4,731 students
