The absolute uncertainty in the volume of the cube is 0.06 m³.
We need to know about the uncertainty of measurement to solve this problem. The uncertainty of cube volume can be determined by
V = s³
|ΔV| = dV/ds x Δs
where V is volume, s is length, ΔV is uncertainty in the volume and Δs is the uncertainty of length.
From the question above, we know that
s = 1.00 m
Δs = 2% of s = 2/100 x 1 = 0.02 m
By using the uncertainty of volume formula, we get
|ΔV| = dV/ds x Δs
|ΔV| = d(s³)/ds x Δs
|ΔV| = 3s² x Δs
|ΔV| = 3. 1² x 0.02
|ΔV| = 0.06 m³
Hence, the uncertainty in the volume is 0.06 m³.

Answer:
Explanation:
As per the Kepler's law of planetary motions :
1- The orbits are of elliptical shape having two foci and Sun is located on one foci.
2- The line segment that joins a planet and the Sun sweeps out equal are at equal interval of time.
3- The orbital period square is directly proportional to the cube of semi major axis of its orbit.
Kepler's law are applied on each of the planets of our solar system as the distance of the Sun from the planet is calculated through this.
For example : from Kepler's first law we can see the eccentricity of the Earth's orbit is 0.0167.
Answer:
c. the Sun
Explanation:
Considering the description made in the question about the atom of a lead with atomic number 82, the place t his atom probably have NOT been during the course of its existence is the SUN
The reason is that SUN is believed to consist of ten significant elements, which are: Hydrogen, Helium, Oxygen, Carbon, Nitrogen, Silicon, Magnesium, Neon, Iron, and Sulfur.
Also, some of the properties of lead show that it won't have existed in the Sun before. For example, it is a poor transmission of heat. Also, it doesn't react with oxygen in the air and doesn't burn as well.
A single electron has a charge of
Therefore, if we have an excess of
electrons, the total net charge will be the product between the charge of a single electron and the total number of electrons in excess:
