Answer:

As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer. There are two basic types of waves: mechanical and electromagnetic

Answer:

Velocity, because it has both magnitude and direction.

Step-by-step explanation:

Velocity is the rate at which an object changes position in a specific direction. It has both magnitude and direction.

The family is travelling south at 105 km/h. This is an example of velocity, because it has magnitude (105 km/h) and direction (south).

100.0 g of water was placed in a simple, constant-pressure calorimeter. The temperature of the water was recorded as 295.0 K. A

Marizza181 [45]

Answer:

$296.05\ \text{K}$

Explanation:

$m_w$ = Mass of water = 100 g

$c_w$ = Specific heat of water = $4.184\ \text{J/g K}$

$m_c$ = Mass of copper = 20 g

$c_c$ = Specific heat of copper = $0.385\ \text{J/g K}$

$\Delta T_w$ = Temperature change in water = $(T-295)$

$\Delta T_c$ = Temperature change in cooper = $(353-T)$

T = Final temperature of the system

The heat balance of the system is given by

$m_wc_w\Delta T_w=m_cc_c\Delta T_c\\\Rightarrow 100\times 4.184\times (T-295)=20\times 0.385\times (353-T)\\\Rightarrow 418400\left(T-295\right)=7700\left(353-T\right)\\\Rightarrow 418400T-123428000=2718100-7700T\\\Rightarrow T=\frac{1261461}{4261}\\\Rightarrow T=296.05\ \text{K}$

The final temperature of the water is $296.05\ \text{K}$ .
