Answer:
Density = 1.1839 kg/m³
Mass = 227.3088 kg
Specific Gravity = 0.00118746 kg/m³
Explanation:
Room dimensions are 4 m, 6 m & 8 m. Thus, volume = 4 × 6 × 8 = 192 m³
Now, from tables, density of air at 25°C is 1.1839 kg/m³
Now formula for density is;
ρ = mass(m)/volume(v)
Plugging in the relevant values to give;
1.1839 = m/192
m = 227.3088 kg
Formula for specific gravity of air is;
S.G_air = density of air/density of water
From tables, density of water at 25°C is 997 kg/m³
S.G_air = 1.1839/997 = 0.00118746 kg/m³
Answer:
-30 m
Explanation:
50-20 but the direction is going west so it’s negative
The force of gravity between them increases.
Answer:
v = 42.33 m/s
Explanation:
The time difference between two pulses that are emitted by Police is observed in the interval

now the speed of the electromagnetic wave is given as

now the distance traveled by them



so distance of speeding vehicle covered for round trip of wave is 38.1 m
now for one trip it is given as d = 19.05 m
now the speed of the vehicle is given as



I think the answer to your question is twenty-four percent.
