In a science experiment, the dependent variable is the thing that will change based on what else is happening in the experiment. The independent variable is the thing that stays the same every time.
<h3><u>Answer;</u></h3>
Potassium chloride
<h3><u>Explanation;</u></h3>
- Potassium Chloride is an ionic compound and has ionic bond which is stronger than covalent bond in ethyl alcohol,water ,ammonia, and thus has the highest boiling point .
- ionic bond is a type of bond that results from the transfer of electrons between metallic atoms and non-metallic atoms.
To develop this problem it is necessary to apply the concepts related to frequency from Hooke's law.
By Hooke's law we know that the Force is defined as
Where,
k = Spring constant
Displacement
at the same time Force can be defined by Newton's second law as,
F = mg
Where,
m = mass
g = gravity
Equating we have
Frequency and oscillation can be defined as
Then replacing,
Answer:
a
Explanation:
Using fences.................................
Answer:
48.5 hp
Explanation:
= mass of the car = 1200 kg
= initial speed of the car = 25 km/hr = 6.94 m/s
= final speed of the car = 100 km/hr = 27.78 m/s
= time interval = 12 s
Power output of the engine is given as
W
we know that , 1 hp = 746 W
hp
