Answer:
0.15kg/m³
Explanation:
Density = mass/ volume
Given that
Mass = 150kg
Note that volume = length x breadth x height
Volume = 20 x 10 x 5
Volume = 1000m³
Density = mass ➗ volume
Density = 150kg ➗ 1000m³
Density = 0.15kg/m³

Answer:
1. Decreases,
2. Increases,
3. Increases
Explanation:
The heat which is a product of sun's energy, is transferred from the sun to the earth through radiation, conduction or convention. This heat passes through the earth atmosphere, then warms it , before becoming heat energy.
Therefore, Heat is transferred from the sun to the earth via electromagnetic waves . Because of this transfer, the entropy of the sun DECREASES, the entropy of the earth INCREASES and the entropy of the sun-earth system INCREASES.
Answer:
F = 200 N
Explanation:
Given that,
The mass suspended from the rope, m = 20 kg
We need to find the resultant force acting on the rope. The resultant force on the rope is equal to its weight such that,
F = mg
Where
g is acceleration due to gravity
Put all the values,
F = 20 kg × 10 m/s²
F = 200 N
So, the resultant force on the mass is 200 N.
