Answer:
2. The charge transfers to the leaves through the metal ball. Since the leaves have the same charge, they are pushed away from each other.
Explanation:
As we know that two similar charges always repel each other and two opposite charges always attracts each other
So here we know that when a charged body is in contact with the metal ball then we know that metal is good conductor so through this metal ball charge is transferred to the the thin metal plates
Now this metal plate will separate by mutual repulsion force on them and they moved apart
So correct answer will be
2. The charge transfers to the leaves through the metal ball. Since the leaves have the same charge, they are pushed away from each other.

Answer:
basaltic cinder cone
Explanation:
The volcano consists of a black ("negro") basaltic cinder cone with associated lava flows, including an aa flow field reaching 4 km to the NE and SW. The frequent eruptions of Cerro Negro have modified its morphology continuously since its birth 160 years ago
Chameleon's tongue is more fast than thought. Its long sticky tongue moves at an amazing ballistic speed which lashes out unsuspecting insects and bugs. Now let us see how fast it is.
GIven:
acceleration of the chameleon's tongue- 260 m/s
2 for 20 ms
constant speed 30 ms
50 ms total time
1/20 of a second
solution:
<u>260</u> = <u> n</u><u> </u>
20 50
<u>20 n </u>= <u>13, 000</u>
20 20
n= 650 m/s
