Answer:
<em>The mass of mercury = 0.136 kg</em>
Explanation:
Density: This is defined as the ratio of mass of a body and the volume of that body. The S.I unit of density is kg/m³. It can be represented mathematically as
D = m/v
m = D× v .......................... Equation 1
Where D = density of the mercury, m = mass of the mercury, v = volume of the mercury.
<em>Given: D = 13600 kg/m², v = 10 cm³ = (10×1/1000000) = 0.00001 m³</em>
<em>Substituting these values into equation 1,</em>
<em>m = 13600×0.00001</em>
<em>m = 0.136 kg.</em>
<em>Therefore the mass of mercury = 0.136 kg</em>
The most suitable option would be C take baths instead of showers.
When doing this, you are using just an amount of water and you avoid water to keep on running. The main idea should be to reduce water usage so you need to pay attention not only when you take a bath but also when you brush your teeth. leave the water running while doing anything is one of the ways in which water is highly wasted
Answer:
Explanation:
Given that,
The mass of the Jupiter,
The radius of Jupiter,
We need to find the acceleration due to gravity on Jupiter. The formula is
Put all the values,
So, the value of acceleration due to gravity on the Jupiter is .
Answer:
11.3 g
Explanation:
given,
density of the lead = 11.3 g/cm³
volume = 1 cm³
mass of the lead = ?
we know,
mass = volume x density
mass = 1 x 11.3
mass = 11.3 g
hence, the mass of the lead is equal to 11.3 g
