Answer:
The electron microscopes are uses the electron to produce the image of the any object.The area where the electron passes then that area appeaser white but on the other hand where the electron does not pass that area appears black.But this does not give any information about the color of light it shows only white and black areas.We also know that color is the property of photons ( light).So the microscopes does not produce color of the image.
Answer:
Increasing the number of trials reduces the impact of any one imprecise measurement. … To increase the number of attempts, you can find an average result for the experiment, as well as find and discrepancies as human error if you perform an experiment several times.

Answer: Arthur
Explanation: This is a question under the concept of circular motion.
We will model the distance away from the axis of rotation as the radius of the circular motion (r).
for Arthur,
Angular speed (ω) = 25 rad/s
Radius = 1.5m
The linear (tangential) velocity is gotten as
v = ωr
v = 25 × 1.5
v = 37.5 m/s
For Blake
ω = 30 rad/s and r = 1.1m
v = ωr
v = 30 × 1.1
v = 33 m/s
Since the linear speed of Arthur's throw is faster than that of Blake's, it implies that the discus of Arthur will travel a father distance than that of Blake.
Answer:
The first law of thermodynamics. In brief, energy can neither be created nor destroyed. However, energy may be converted from one form to another.
Explanation:
A basic electrical solar fan comes in two parts: a solar panel connected to an electrical motor. The solar panel converts solar energy to electricity; the electrical motor converts electricity to mechanical energy, which causes the blades to turn.
This energy conversion is possible because of the first law of thermodynamics. This law states that the total energy of the universe is constant. Energy can neither be created nor destroyed. However, energy may be converted from one form to another.
For example, the solar panel does not destroy the solar energy; it simply converts that energy to electrical energy. Note that a fraction of that energy absorbed was lost as thermal energy. Similarly, the motor merely converts electrical energy to mechanical energy. It might also lose some thermal energy as it heats up.
