Answer:
50m/s
Explanation:
The formula for calculating speed of wave in relation to frequency and wavelength is
C=λf
Where c is the speed of the wag
λ is the wavelength which is 1m
f is the frequency which is 50Hz
From the formulas,
C= 50X1
C= 50m/s
The chart is about atomic structure: at the top, the left box is "nucleus" and the right is "electron cloud".
On the left, under nucleus, the two boxes are: "protons" on the right and "neutrons" on the left. Under proton is elements which is given and under neutrons, it is "isotopes".
On the right, under electron cloud, the next box is "electrons" and then the lower box is "ions".
B. Newton
Is the metric unit of force
Answer:
D)
Explanation:
This seems like a weird question
Water is held together by covalent bonds. The amount of energy required to break these bonds so that water would split into it's respective ions is pretty high. The chances that any one of the molecules floating in 1L of water get enough energy to spontaneously burst into it's ions is slim to none.
So, D) seems like the most likely answer
C) a chemical change.
Chemical reactions will always convert a certain chemical(s) into one or more products.
