Answer:
I believe it is C.
Explanation:
I believe this because Scientist could not discover this without evidence.
And a law would not do anything but give them more reason to support the theory of plate tectonics.
And the seafloor could be a possible outcome but i know for a fact that scientist have a device that can go into earth's core to study the movements.
This is why i believe it is C.
Sorry if it is wrong im new to this.
B Is your answer research info about your question
Reasoning is because c) has nothing to do with the scientific method a) is where you text your hypothesis and d) is a conclusion which is the final results of your experiment
Answer:
A. Time, t = 4.35s
B. Height of its fall, S = 92.72m
Explanation:
Vo = 0 m/s
Vi = 0.46h m/s
S = h m
a = 9.81 m/s2
To calculate the time taken, we need to get the value of the distance, h.
Using the equations of motion,
Vi^2 = Vo^2 + 2aS
Where Vi = final velocity
Vo = initial velocity
a = acceleration due to gravity
S = height of its fall
(0.46h)^2 = 0 + 2*9.81*h
0.2116h^2 = 19.62h
h = 19.62/0.1648
= 92.722 m
To calculate the time,
S = Vo*t +(1/2)*a*t^2
92.772 = 0 + (1/2)*9.81*t^2
t^2 = 185.44/9.81
= 18.904
t = sqrt(18.904)
= 4.348 s
The correct matches are as follows:
- malleability - the ability of metals to be shaped by hammering or pounding
- metallic bond - the bond formed when metal atoms share many mobile electrons
- alloy - a mixture of the atoms of a metal with another element
- ductility - the ability of metals to be formed into wires
- electron sea theory - metals bond to other metals by sharing many "floating electrons
<h3>What are metals?</h3>
Metals are elements which form positive ions by loss of electrons.
Metals are usually shiny, malleable and ductile.
Metal atoms combine are bonded to each other by metallic bonds.
Electron sea theory describe how mobile electrons surround positive atomic nucleus.
Alloys refer to a mixture of metals.
In conclusion, metal atoms form metallic bonds.

Explanation:
It is known that general formula to calculate the volume of a cone is as follows.
Volume of the cone =
and here, r =
So, V =
On putting the given values into the above formula we will calculate the value f h as follows.
V =
=
=
Now, we will differentiate w.r.t t as follows.
=
It is given that water here flows at a rate of 1.5 and h = 1.1 m.
1.5 =
1.5 =
= 0.888
= 0.9 m/min (approx)
Thus, we can conclude that the water level is rising at a rate of 0.9 m/min.
