Answer:
What is the question?
Explanation:
If you tell me the question I can help.
Answer:
1. Velocity = 75.39 m/s
2. Air resistance
3. Mass of the coin
Explanation:
1. Given that the height of the building is 290 m. From Newton's third law of motion,
=
+ 2gh
where: V is the final velocity of the coin, U is the initial velocity, g is the force of gravity and h is the height.
Since the coin was dropped from a height, its initial velocity is zero. The force of gravity is taken as 9.8 m/
, so that:
= 0 + 2 x 9.8 x 290
= 5684
V = 
= 75.3923
The velocity with which the coin hits the ground is 75.39 m/s.
2. Air resistance: During the free fall of the coin, the direction of wind flow could either cause an increase or decrease the value predicted.
ii. Mass of the coin: This can also affect the predicted value.
Answer:

= average acceleration
= final velocity
= starting velocity
= elapsed time

C. Bottom
Titania speaks these words as she is under the enchantment of the magic flower, it makes her fall in love with the first thing she sees. It's comedic because Bottom is also enchanted to have the head of a donkey, so she's claiming that this peasant with a donkey head is both wise and beautiful. The reality being that he is as wise as he is beautiful, in that he is neither beautiful nor wise.
Answer: Option C: The number of positive and negative charges can be same.
A substance is said to be polarized when there is non-uniform distribution of electric charge. When there gain or loss of electrons, ions are formed. It is not necessary that polarized object is metal. For example, Water is polarized. The oxygen atoms have partial negative charge and hydrogen atoms have partial positive charge.
