Answer:
100 Watts
Explanation:
<u>These equations are needed to work out the answer:</u>
- power= work done/ time taken
- work done= force* distance
- force= mass* acceleration
force: 10 kg* 2m/s= 20
work done: 20* 10m=200
power: 200/2=100
Answer: I would say static electricity.
Explanation:
Johannes Kepler contributed to the study of planets : He provided mathematical support for the heliocentric model.
<h3>What is Kepler's first law of planetary motion?</h3>
Kepler's first law of planetary motion states that the planets revolve around the Sun in orbits elliptical in shape with the Sun at its one of the focus.
As the planets rotate around the Sun, the relative distance between the Sun and planets increases and decreases.
The heliocentric model in which the Earth and planets revolve around the Sun at the center of the universe. Johannes gave the mathematical calculations of this model.
Thus, last option is correct.

If iron (Fe) has an atomic mass of 56 amu, oxygen (O) has an atomic mass of 16 amu, and hydrogen (H) has a mass of 1 amu, the atomic mass of Fe(OH)3 would be 107amu (option B).
<h3>What is atomic mass?</h3>
Atomic mass is the average mass of atoms of an element. The mass number of a compound can be calculated by summing the atomic masses of each element in the compound.
According to this question, the periodic table reveals that iron (Fe) has an atomic mass of 56 amu, oxygen (O) has an atomic mass of 16 amu, and hydrogen (H) has a mass of 1 amu.
The atomic mass of Fe(OH)3 can be calculated as follows:
= 56 + (16 + 1)3
= 56 + 51
= 107amu
Therefore, if iron (Fe) has an atomic mass of 56 amu, oxygen (O) has an atomic mass of 16 amu, and hydrogen (H) has a mass of 1 amu, the atomic mass of Fe(OH)3 would be 107amu.
