Answer:
Explanation:
To analyze the behavior of black bears during the night. To describe how black bears adapt to life near human. To evaluate the decline in the number of black bear.
Answer:
A) 4.66 cm
B) 25.56 cm
Explanation:
A) real depth of fish = 6.2 cm
apparent depth =d
Now 
= 1.33
d = 4.66 cm
B) Image of fish will be formed 13.9 cm behind the mirror so its position from
surface of water will be
20.1 + 13.9 = 34 cm . This will be real depth of image
If D be its apparent depth then
\frac{34}{D}=1.33
D =\frac{34}{1.33}
D = 25.56 cm

In the freezing physical change, when 210.0 g of water a 0 degrees freezes into ice, it gives off 71.0 kJ of heat.
<h3>What is freezing?</h3>
It is a physical change in which liquids give off heat to form solids.
We have 210.0 g of water at 0°C. We can calculate the amount of heat given off when it freezes into ice using the following expression.
Q = ΔH°fus × m
Q = 0.334 kJ/g × 210.0 g = 70.1 kJ
where,
- Q is the heat released.
- ΔH°fus is the latent heat of fusion.
- m is the mass.
In the freezing physical change, when 210.0 g of water a 0 degrees freezes into ice, it gives off 71.0 kJ of heat.

I<span>n the absence of air resistance, all objects fall with the same acceleration due to gravity.
The acceleration of gravity does not depend on mass of the object
