Answer:
Explanation:
The charge on one object, 
The distance between the charges, r = 0.22 m
The force between the charges, F = 4,550 N
Let q₂ is the charge on the other sphere. The electrostatic force between two charges is given by the formula as follows :
So, the charge on the other sphere is 
.

Answer:
The scientific method is the process by which scientists gain confidence in theories by failing to prove them wrong.
Explanation:
Scientific method is a step by step process of creating and carrying out experiments. These processes to be performed are derived from logical and rational application of knowledge concerning a particular subject matter. Through these processes, scientists reach a conclusion about the world, these makes them confident in their findings.
The steps involved in scientific method include:
Observation: it is the first step. It enables you organise in your mind how you want the experiment to.
HYPOTHESIS is the result you imagine you'll find.
PREDICTION is how you think about the scientific idea- It solely relies on the hypothesis made.
EXPERIMENT is used to test your hypothesis. It is the tool designed to check if your idea is right or wrong.
CONCLUSION is the final step. It is the result gotten from the experiment. It can approve the hypothesis or reject the hypothesis.
A theory is formed when hypothesis has been tested to be true by many scientists. Hence scientists gain confidence in theories when the scientific method is approved.
A scientific theory is a well-approved explanation of an aspect of the natural world. The approval is based on thoroughly confirmed hypothesis and experiments carried out by many scientists.
Answer:
Amplitude.
Explanation:
The velocity of a wave is given by :
velocity = total distance covered/total time taken
In the case of a wave the total distance covered is equal to the amplitude of a wave. It is the maximum displacement covered by the wave. So, the velocity of a wave is a function of its amplitude. Hence, the correct option is (D).
The Unification of Germany into the German Empire, a Prussia-dominated nation state with federal features,[1] officially occurred on 18 January 1871 at the Versailles Palace's Hall of Mirrors in France. Princes of the German states gathered there to proclaim Wilhelm of Prussia as Emperor of the German Empire after the French capitulation in the Franco-Prussian War.
