The eyepiece, also called the ocular lens, is a low power lens. The objective lenses of compound microscopes are parfocal. You do not need to refocus (except for fine adjustment) when switching to a higher power if the object is in focus on a lower power. The field of view is widest on the lowest power objective.
Answer:
C. Chemical energy
Explanation:
The different types of energy listed in this question are:
A) Electrical energy: it is the energy related to the flow of electrical charges (current)
B) Nuclear energy: it is the energy contained in the nuclei of the atoms, and released during nuclear reactions
C) Chemical energy: it is the energy contained in the bonds between molecules, and it is released during chemical reactions
D) Thermal energy: it is the energy associated with the motion of molecules
Photosynthesis is the process that plants use to transform the light energy (coming from the Sun) into chemical energy. In fact, in this process, plants absorb CO2 (from the atmosphere) and solar energy (from the light), and they convert them into sugars (glucose) and oxygen. Therefore, the initial energy coming as solar energy is converted into energy of the bonds of the molecules of glucose (so, chemical energy).
So, the correct option is C).
They start at 1 meter and after 10 seconds they've moved to 6 meters.
6 - 1 = 5 meters
Answer:
7.2 x 10⁻⁶N
Explanation:
Given parameters:
Mass of Venus = 4.87 x 10²⁴kg
Radius = 6.05 x 10⁶km = 6.05 x 10⁹m
Mass of person = 81kg
Unknown:
Gravitational force = ?
Solution:
To solve this problem, we use the Newtons law of universal gravitation:
Fg =
G is the universal gravitation constant = 6.67 x 10⁻¹¹
Fg =
Fg = 7.2 x 10⁻⁶N
