Answer:
(c) reduce atmospheric blurring
Explanation:
Observatories are the locations used to study the celestial events, climate, astronomy etc. As the observations are made with the radio and visible light of the electromagnetic radiations. So in order to have the clear view, observatories are made at higher places far from population, in the dark areas having clear air, where they can clearly observe the sky. Atmospheric blurring is caused by the atmospheric turbulence. That cause the light coming from the stars to get slightly refracted thus effecting the results of the telescopes. In order to overcome it observatories are made at specific places like on the highest mountaintops.
Answer:
The strength of the source charge's electric field could be measured by any other charge placed somewhere in its surroundings. The charge that is used to measure the electric field strength is referred to as a test charge since it is used to test the field strength. The test charge has a quantity of charge denoted by the symbol q.
Explanation:
Electric field strength is a vector quantity; it has both magnitude and direction. The magnitude of the electric field strength is defined in terms of how it is measured. Let's suppose that an electric charge can be denoted by the symbol Q. This electric charge creates an electric field; since Q is the source of the electric field, we will refer to it as the source charge. The strength of the source charge's electric field could be measured by any other charge placed somewhere in its surroundings. The charge that is used to measure the electric field strength is referred to as a test charge since it is used to test the field strength. The test charge has a quantity of charge denoted by the symbol q. When placed within the electric field, the test charge will experience an electric force - either attractive or repulsive. As is usually the case, this force will be denoted by the symbol F. The magnitude of the electric field is simply defined as the force per charge on the test charge.
