Answer: The answer is B, The variable that should go on the x- axis is the temperature of water.
Explanation: In an experiment, we must have two variables; the independent variable and the dependent variable.
If the results of the experiment is reported in graphical format, the independent variable is plotted on the x axis while the dependent variable is plotted on the y axis.
In this case, the independent variable is the temperature of the water while the dependent variable is the mass of salt dissolved in 100 mL of water.
Therefore, the variable that should go on the x- axis is the temperature of water.
The answer is w=p.t. Substitution:hz 110.20.
Answer:
1.6 pF
Explanation:
The capacitance of a parallel-plate capacitor in air is given by:
where
is the vacuum permittivity
A is the area of each plate
d is the separation between the plates
In this problem we have:
- Separation between the plates: d = 5.00 mm = 0.005 m
- Area of the plates: 
Therefore, the capacitance is
Explanation:
Given that,
Magnitude of vector A, |A| = 15
Magnitude of vector B, |B| = 25
We need to find the magnitude of this sum.
The maximum sum of the resultant vector,
The minimum sum of the resultant vector,
So, the magnitude of this sum either 45 or -10.
By Newton's second law, the net force on the object is
∑ <em>F</em> = <em>m</em> <em>a</em>
∑ <em>F</em> = (2.00 kg) (8 <em>i</em> + 6 <em>j</em> ) m/s^2 = (16.0 <em>i</em> + 12.0 <em>j</em> ) N
Let <em>f</em> be the unknown force. Then
∑ <em>F</em> = (30.0 <em>i</em> + 16 <em>j</em> ) N + (-12.0 <em>i</em> + 8.0 <em>j</em> ) N + <em>f</em>
=> <em>f</em> = (-2.0 <em>i</em> - 12.0 <em>j</em> ) N
