Your answer is D. Earthquakes and hot spots occur along convergent plates.
Answer:
Temperature is a measure of the average energy of molecular motion in a substance. In everyday usage, temperature indicates a measure of how hot or cold an object is. Temperature is an important parameter in chemistry. When a substance changes from solid to liquid, it is because there was in increase in the temperature of the material. Chemical reactions usually proceed faster if the temperature is increased.
Absolute zero is the lowest temperature in Kelvin which all motion stops. Absolute zero is called 0 Kelvin (0 K), and it is equivalent to –273.15°C or –459.67°F.
The position of the object is = -68cm
The magnification of the mirror= 0.3
<h3>Calculation of object distance</h3>
The image distance = 20.5cm
The focal length= R/2 = 31.5/2= 15.75
The object distance= ?
Using the lens formula,1/f = 1/v-1/u
1/u = 1/v- 1/f
1/u = 1/20.5 - 1/15.75
1/u = 0.0489- 0.0635
1/u = -0.0146
u = -68cm
The magnification of the mirror is image size/object size
= 20.5cm/-68cm
= 0.3

The correct answer is: 
electrons/second
Explanation:
5A current is passing through the copper wire and the light bulb; it means that 5 Coulombs of charge per second is passing through the wire (as current = coulombs/second). To find the electrons per second, the following formula is used:
Electrons per second =
