<h2>Answer:</h2>

<u>The correct statement is </u><u>A nondigital camera uses film to record images, and a digital camera uses sensors.</u>

<h2>Explanation:</h2>

A non digital camera uses a film and it works on the basis of light which is either produced by the flash light or sunlight. On the other hand a digital camera has its own sensors which has the ability to provide an option of low light compensation and it also allows the user to adjust the light controls digitally with the help of existing sensors.

D. Digital cameras use sensors which detect the brightness and color of the light, while non-digital cameras project the light onto film, which develops over time.

Setler [38]

Answer:

final temperature will be 0 degree C

Total amount of ice will be

$m_{ice} = 182 g$

total amount of water

$m_{water} = 17 g$

Explanation:

After thermal equilibrium is achieved we can say that

Heat given by water = heat absorbed by ice cubes

so we will have

Heat given by water to reach 0 degree C

$Q_1 = m_1s_1 \Delta T_1$

$Q_1 = 0.030(4186)(50 - 0)$

$Q_1 = 6279 J$

heat absorbed by ice cubes to reach 0 degree

$Q_2 = m_2 s_2 \Delta T_2$

$Q_2 = (0.169)(2100)(30)$

$Q_2 = 10647 J$

so we will have

$Q_2 > Q_1$

so here we can say that few amount of water will freeze here to balance the heat

$10647 - 6279 = mL$

$m = \frac{10647 - 6279}{335000}$

$m = 13 g$

so final temperature will be 0 degree C

Total amount of ice will be

$m_{ice} = 84.5 + 84.5 + 13$

$m_{ice} = 182 g$

total amount of water

$m_{water} = 30 - 13$

$m_{water} = 17 g$

What is the difference between balanced force and action reaction force

Vilka [71]

Answer:

Balanced forces are equal and opposite forces that act on the same object. ... Action-reaction forces are equal and opposite forces that act on different objects, so they don't cancel out. In fact, they often result in motion.
