<span>C. A concave lens can only form a virtual image, because they are thinner in the middle and thicker around the edges.</span>
The gravitational potential energy of the weight changes to motion energy when the weight moves down and the paddle wheel spins. The motion energy changes to thermal energy, causing the water’s temperature to rise.

Answer:
0.001225 kg/L × 720 000 000 L = 882000 kg
Explanation:
Given:
The equation to solve is given as:
0.001225 kg/L × 720 000 000 L = ?
Let us write each term of the product in terms of power of 10.
As 0.001225 has 6 digits after the decimal place, therefore, we use the exponent 6 for 10 and the sign is negative. This gives,
Now, for 720000000 L there are 6 zeros after 720. So, we use exponent 6 but with a positive sign. This gives,
Now, finding the product, we get:
Therefore, the product is equal to:
0.001225 kg/L × 720 000 000 L = 882000 kg
Answer:
0 degrees
Explanation:
this is because when the light ray hits a surface a medium at 90 degrees then the angle of incidence = 0 , thus light doesn't bend when it enters the medium, no bending means angle of refraction is 0 degrees
hope this helps ,please mark it
Earth quakes are commonly found along fault lines or tectonic plates.
Hope this helped :-) <span />
