Answer:
Because water is water and its a liquid meanwhile plants are plants living things that you can move around.
Explanation:
Bar graphs show data involved in distinct categories that do not overlap; whereas, pie charts show data as parts out of a whole (such as out of 100%).
Answer:
Final temperature of the copper is 59 degrees Celsius
Explanation:
It is given that,
Mass of the sample of copper metal, m = 6.5 g
Initial temperature of the metal, 
Heat generated, Q = 84 J
The specific heat capacity of liquid water is 0.38 J/g-K
Let
is the final temperature of the copper. It can be calculated using the definition of specific heat of any substance. It is given by :





or

So, the final temperature of the copper is 59 degrees Celsius. Hence, this is the required solution.
Answer:
Wave X is moving the fastest.
Explanation:
As we know that the speed of the wave is given as the product of frequency and wavelength
so here we will have

now for wave X

now the speed of this wave is

now for wave Y

now the speed of this wave is

now for wave Z

now the speed of this wave is

So correct answer will be
Wave X is moving the fastest.
Answer:
Proof:
|----------(R1)-------------(R2)---------|
Let the resistances be R1 , R2 connected in series. And the potential difference be V ;
We know that :
P1 = V²/R1 ..........(1) and
P2 = V²/R2 ...........(2)
In series combination , the net resistance is the algebraic addition of individual resistance :
R = R1 + R2
=> V²/P = V²/P1 + V²/P2
=> 1/P = 1/P1 + 1/P2
