Answer:
Explanation:
When the positively charged half shell is brought in contact with the electroscope, its needle deflects due to charge present on the shell.
When the negatively charged half shell is brought in contact with the positively charged shell , the positive and negative charge present on each shell neutralises each other .So both the shells lose their charges .The positive half shell also loses all its charges
When we separate the half shells , there will be no deflection in the electroscope because both the shell have already lost their charges and they have become neutral bodies . So they will not be able to produce any deflection in the electroscope.
Ultraviolet rays from the sun are very strong, therefore if direct contact is made with skin, it could cause sun burn, or in a worser case skin cancer
catholic I did this a while back but wyd you mark it physics
Answer:
My answer is 250m/sec
Explanation:
the formula is clearly
Speed = <u>Distance</u>
Time
Speed = <u>5</u><u>0</u><u>0</u><u>m</u><u>e</u><u>t</u><u>e</u><u>r</u><u>s</u><u> </u> (Divide the two)
2seconds
Speed = 250m/sec
Word for a tiny piece of matter that cannot be divided is B - Atom
