Answer:
c. absorbs all the energy that strikes it.
Explanation:
<em>An ideal black body is an object that absorbs every light energy (irrespective of the wavelength and direction) that strikes it without reflecting any in return. </em>
<em>Such objects or bodies usually appear perfectly black and will only emit radiation when heated to a very high temperature.</em>
Answer:
The objects were 1.8m apart.
Explanation:
We will start stating the Coulomb's Law. It says that:

Where F_e is the electric force between the objects, q_1 and q_2 are the magnitude of the charge of the objects, r is the distance between them and K is the Coulomb's constant (
in vacuum). Solving for the distance r we have:

Plugging the given values into this equation, we obtain:

In words, the two charged objects were 1.8m apart.
Explanation:
The acceleration g varies by about 1/2 of 1 percent with position on Earth's surface, from about 9.78 metres per second per second at the Equator to approximately 9.83 metres per second per second at the poles.
Answer:
Lifeless because of the lack of rain
It might make more sense putting it another way but this is basically it. you just take the minutes and divide them by 60 to convert them to hours. then simplify the ratio
