Answer:
60.87 °C
Explanation:
Applying,
Heat lost = heat gain
cm'(t₂-t₃) = cm(t₃-t₁).............. Equation 1
Equation 1 can futher be simplified to
m'(t₂-t₃) = m(t₃-t₁)................Equation 2
Where m' = mass of the hot water, m = mass of the cold water, t₁ = initial temperature of the cold water, t₂ = initial temperature of the hot water, t₃ = temperature of the mixture.
From the question,
Given: m' = 88 g, m = 32 g, t₁ = 22°C, t₂ = 75°C
Substitute these values into equation 2
88(75-t₃) = 32(t₃-22)
6600-88t₃ = 32t₃-704
32t₃+88t₃ = 6600+704
120t₃ = 7304
t₃ = 60.87 °C
- One way Light waves differ from sound waves it that it does not require a medium to propagate.
- High frequency electromagnetic waves are more likely to cause harm because as a wave's frequency increases, more energy is carried by the wave in a given time period.
- The frequency of yellow light is greater than that of blue light.
<h3>What is a Wave?</h3>
This is defined as a propagation of disturbances from place to place in a regular and organized way.
The answers provided above are therefore the most appropriate choices in this scenario.

A shovel would classify as choice (A) because the head of the shovel is the wedge while the body of the shovel is the lever
Answer:
θ = 66.90°
Explanation:
we know that
I= intensity of polarized light =1
I_o= intensity of unpolarized light = 13
putting vales we get
⇒
therefore θ = 66.90°
