First we have to calculate the volume of the living room:
V = L x W x H = 4.5 m * 3.4 m * 2.9 m
V = 44.37 m³
We know that Density = 1.29 kg/m²
D = m / V
m = D · V
m = 1.29 kg/m³ · 44.37 m³
m = 57.2373 kg ≈ 57.2 kg
Answer: The approximate mass of air in living room is 57.2 kg.
Answer:
27 cm squared

Answer:
TRUE
Explanation:
Desertification is usually defined as the process by which a productive land is transformed into a desert. This process occurs mainly in the arid, semi-arid as well as in the dry sub-humid areas, where there occurs less amount of rainfall and presence of less or no moisture content in the air.
It is caused by various processes, such as-
- Cutting down of trees, in order to make urban areas.
- Low level of groundwater.
- Forest-fire can also lead to desertification, as the trees are burned by this process.
- Soil erosion also is a major cause.
- It also occurs due to changes that occur in the climate of the area.
Thus, the above-given statement is true.
Answer:
The magnitude of the electric field strength = 7.2 x 10⁸ N/C
Explanation:
The linear density:
Point r = 3 cm = 3/100 m
r = 0.03 m
The electric field strength is calculated below
The magnitude of the electric field strength = 7.2 x 10⁸ N/C
