Answer:
(B) 39
Explanation:
Use synthetic division:
-2 | 3 0 -1 3 1
____<u>-6 12 -22 38</u>
3 -6 11 -19 | 39
This means that the remainder is 39
We first calculate the acceleration on the ball using:
2as = v² - u²; u = 0 because ball is initially at rest
a = (36)²/(2 x 0.35)
a = 1850 m/s²
F = ma
F = 0.058 x 1850
= 107.3 Newtons
Given:
The battery voltage, V=200 V
The current through the resistor, I=50000 mA=50000×10⁻³ A
To find:
The resistance of the resistor.
Explanation:
From Ohm's law, the voltage across a circuit is directly proportional to the current through the circuit.
Thus the voltage across the resistor is given by,
On substituting the known values in the above equation,
Final answer:
The resistance of the resistor is 4 Ω
The ideal mechanical advantage (IMA) can be determined by the following equation:
IMA= Input distance/Output distance
The Input distance and Output distance are:
Input distance=220 meters
Output distance=110 meters
When you substitute in the equation of the ideal mechanical advantage (IMA), you obtain:
IMA= Input distance/Output distance
IMA= 220 meters/110 meters
IMA=2
Usually start on the internet, there is bound to be something or a form of information on it.
