Answer:
A) C is 2 units towards right
B) C is 9 units towards right and 3 units towards up
C) C is 4 units towards right and 1 unit towards down
Explanation:
Drawings are given in the attachment.
A)Since,
A is 4 units towards right,
B is 1 unit towards left,
Then,
C is 2 units towards right.
B) Since,
A is 4 units towards right and 2 units towards up,
B is 1 unit towards left,
Then,
C is 9 units towards right and 3 units towards up.
C) Since,
A is 4 units towards right and 2 units towards up,
B is 1 unit towards right, and 1 unit towards down
Then,
C is 4 units towards right and 1 unit towards down.
The find the approximate age of the granite one must know the half-life of potassium-40. The half-life of an element is the period of time in which half atoms of the same substance changes into the isotope of the element. The isotope of potassium-40 is Argon 40. Potassium-40 has a half-life of approximately 1.3 billion years. The rock is approximately 1.3 billion years old.
<span>When the delta brainwave frequencies increase into the frequency of theta brainwaves,
active dreaming takes place and often becomes more experiential to the
person. Typically, when this occurs there is rapid eye movement, which
is characteristic of active dreaming. This is called REM, and is a well
known phenomenon.. Hope that helps!</span>
Answer:
A) is repelled by the sphere.
Explanation:
On rubbing the plastic rod with the wool cloth the rod gains some electrons from the surface of the wool and becomes electrostatically negative in charge.
When this rod is brought near to a neutral metallic sphere then the electrons of the sphere get repelled from the nearest portion of the metallic sphere as it a conductor and the electrons accumulate on the farthest opposite side of the rod.
But when the rod is brought into contact for some time then the from the portion of the rod which is in contact to the sphere loses the electrons from that region to the sphere since plastic is not an electrical conductor so not all the charges travel to the sphere.
Then when the rod is separated, the charges on the sphere spread uniformly and the similar charged rod faces repulsion.
