It will lead to rain. I know this because as the clouds move over water sources like oceans, lakes, and rivers, the water evaporates and rises. The water then liquefies into little water droplets. As the cloud moves over more water the droplets get scrunched up and get bigger over time and soon they get heavy and gravity pulls the droplets down to earth as rain. The End.
D) pumice.
Explanation:
The rock that most likely floats on water after the eruption of Krakatoa volcano is a Pumice.
Pumice is the only rock that floats on water. It's density is less than that of water and so, it will stay afloat.
- From the given options, pumice is the only extrusive igneous rock. Volcanic eruptions are extrusive in nature.
- Granite is an intrusive plutonic rock
- Phyllite and marble are metamorphic rocks.

Answer:
R₈₀ = 146.43 Ω
Explanation:
The resistance of a resistor depends upon many factors. One of the main factors of the change in resistance of a resistor is the change in temperature. The formula for the resistance at a temperature other than 20°C is given as follows:
R₈₀ = R₀(1 + αΔT)
where,
R₈₀ = Resistance of wire at 80°C = ?
R₀ = Resistance of wire at 20° C = 104 Ω
α = Temperature coefficient of resistance for copper = 0.0068 °C⁻¹
ΔT = T₂ - T₁ = 80°C - 20°C = 60°C
Therefore,
R₈₀ = (104 Ω)[1 + (0.0068°C⁻¹)(60°C)]
<u>R₈₀ = 146.43 Ω</u>
Surface tension is the direct measure of the cohesive forces between liquid molecules that allows them to form "film", making it more difficult to move an object through the liquid surface. Compared to other known liqiuds, the surface tension of water is much greater.
The gravitational force between the Earth and the Moon is
Explanation:
The gravitational force between two objects is given by:
where
:
is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between them objects
In this problem, we are given:
(mass of the Moon)
(mass of the Earth)
(distance between Earth and Moon)
Substituting into the formula, we find the force:
