Question

1)what do you mean by accumulation of change

2) what is lightning? how it occur

​

Answer 1

Answer:

1◆ $\huge{\boxed{\blue{\bf{\mathfrak{Definition:}}}}}$ given a rate-of-change function r(t), accumulated change is determined from the area under the r(t) curve. Left rectangles or right rectangles are often used to estimate the area. Accumulated change is often estimated from r(t) data.

2◆ When the positive and negative charges grow large enough, a giant spark - lightning - occurs between the two charges within the cloud. This is like a static electricity sparks you see, but much bigger. Most lightning happens inside a cloud, but sometimes it happens between the cloud and the ground.

Answer 2

Answer:

1. given a rate-of-change function r(t), accumulated change is determined from the area under the r(t) curve. Left rectangles or right rectangles are often used to estimate the area. Accumulated change is often estimated from r(t) data.

2. Lightning is an electric current. Within a thundercloud way up in the sky, many small bits of ice (frozen raindrops) bump into each other as they move around in the air. All of those collisions create an electric charge. After a while, the whole cloud fills up with electrical charges.
