Answer:
<em>A hypothesis</em> is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon.
<em> A law</em> is a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University. ... However, Newton's law doesn't explain what gravity is, or how it works.
Answer:
The magnitude electrical force between the balloons is 14.4 N.
Explanation:
Given that,
Charge on each balloons,
Distance between charged balloons, d = 0.06 m
We need to find the magnitude electrical force between the balloons. We know that two charged particle possess electrical force when placed at a certain distance. The force is given by :
k is the electrostatic constant
So, the magnitude electrical force between the balloons is 14.4 N. Hence, this is the required solution.
Letter B is correct!
A telescope is an observation instrument that collects light from distant objects, focuses light rays in the form of optical images and magnifies them geometrically so that the human eye can see distant objects. What makes this possible is the angular resolution of a telescope, which is the ability to distinguish two nearby objects in the sky, which happens through the relationship between the wavelength of the collected rays and the diameter of the telescope.
