Answer:

Waves; wavelength; electromagnetic energy; ultraviolet light.

Explanation:

Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.

Sound travels faster through solids than it does through either liquids or gases.

Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.

Hence, sound and light are both found as waves, with a variety of wavelength. The sun, a source of light waves specifically, releases a type of electromagnetic energy. It can be found as UVA or UVB types. These lights give off different levels of ultraviolet light, some of wich can be harmful.

Additionally, the ultraviolet spectrum is divided into three categories and these are; UVA, UVB and UVC.

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
