Answer:
144 W
Explanation:
The power absorbed by a resistor is the product of the current passing through it and the voltage drop across it. Hence
Other variations of this formula are derived using Ohm's law,
is the resistance of the resistor. It is what causes the voltage drop.
It depends on how you want to format your data table, as you can create as many columns or rows as you wish, but the important thing is, to display your quantitative data suitably and in the most simple manner. The main reason why data tables are even used, is to simplify and represent the data in an easy to interpret and access form. If your data table has two columns, then the left side would likely be the manipulated variable, or also known as the independent, and the right side would be the responding or dependent variable. To determine which is which, just look at your data and see which one is manipulated (changed) in order to make the other one "respond" or react to the changes (responding variable). In your case it seems that you do have two units, therefore two "sets" of data, so make sure you know which is which. Also, when you put it into your data table, ensure that you put your units in the top labeling row, so you won't have to rewrite (m 3) for every row of data. After that, it should be fairly easy to input your data and such into the table.

Six.
If you want to double the force, you need to double either v or B. Changing the angle does not give totally predictable results. The formula is
F = q*v*B Sin(theta) altering theta isn't linear. Doubling B is. The answer is A
Seven
Seven is correct. The poles on a magnet is where the field is the strongest.
Eight
I can't really answer this question. Much depends on where you are and whether or not the readings are true or erratic. It is taking only one parameter into account where in reality there are many. My guess would be that as you move up the longitude the angle increases. So the answer would be near but not at the north pole. Seek out your notes for confirmation.
Answer:
19.5 m
Explanation:
Using the equation of motion,
For the first 3 seconds,
s = ut +1/2at².......................... Equation 1
Where t = time, u = initial velocity, a = acceleration, s = distance
Note: Since the car starts from rest, u = 0 m/s.
Given: a = 1.0 m/s, t = 3 s, u = 0 m/s
Substitute into equation 1
s = 0×3+1/2(3)²(1)
s = 9/2
s = 4.5
In the remaining five seconds, at a constant velocity,
s' = vt............. Equation 2
Where v = velocity, t = time.
Recall,
v = u+at
v = 0+1(3)
v = 3 m/s.
Also, t = 5 s.
Substitute into equation 2
s' = 3(5)
s' = 15 m.
Total distance = 15+4.5
Total distance = 19.5 m.
Hence the car travels 19.5 m
