I believe the answer is F. This is because, F stands for Fluorine, which is an element and consists of one atom. A molecule consists of TWO OR MORE atoms held together by chemical bonds. F consists of only one atom, which is Fluorine. So the answer is C. Hope helped.
Answer: 12.5 A
Explanation: power = current· voltage P=IU
Current I = P/U= 3000W / 240V
Answer:
Fav = -12209 N
Explanation:
let p1 be the initial momentum of the ball and p2 be the final momentum of the ball. let v1 be the initial velocity of the ball and v2 be the final velocity of the ball.
From Newton's second law of motion, we get that the avarage force acting on the ball is given by:
Fav = Δp/t
= (p2 - p1)/t
= m(v2 - v1)/t
= [(145×10^-3)(-45.3 - 38.9)/(1×10^-3)
= - 12209 N
Therefore, the average force applies on the ball by tha bat is 12209 in the direction opposite to the balls initial direction.
In order to find the solid, you would want the object in which sound travels the fastest
In this case, since in object C, the speed of sound is the fastest, it is the most likely to be a solid
So object C is most likely to be a solid
