Answer:
You've probably noticed that static electricity is more noticeable during the winter months. This is because the air is very dry. In the summer, the humidity and moisture in the air help electrons move more quickly, which makes it harder to build up a big static charge.
Explanation:
Let's see
According to law of conservation of linear momentum
- PE=KE
- KE=mgh
- KE=0.5(9.8)(0.07)
- KE=4.9(0.07)
- KE=0.343J
- KE=343mJ
Answer:
Explanation:
You need to look at this in 3 separate stages, and then sum thedistance from each stage:
Stage 1)
a=2
t=20
=0
We also need to find the final velocity
Stage 2)
a=0
v=40
t=20
Stage 3)
a=-3
=40
=0
So the total distance is
