Karl measures the current through a resistor. What else will he need to measure in order to work out its resistance?
Shkiper50 [21]

Answer:

The voltage (V)

Explanation:

Ohms, in his law, has explained the relationship between current, resistance and voltage.

Ohm's law, which states that the voltage passing through a resistor is directly proportional to both the current and the resistance of the resistor, has the following equation:

V = IR

Where;

V = voltage (volts)

I = current (Amperes)

R = resistance (ohms)

According to this question, Karl measures the current, I, through a resistor. In order to calculate his resistance, R, he will need to measure the voltage, V.

A diver running 1.8 m/s dives out horizontally from the edge of a vertical cliff and reaches the water below 3s later. How high
Marysya12 [62]

We use kinematic equation,

h=ut+\frac{1}{2} gt^2

Here, h is vertical height, u is initial vertical velocity, t is time taken and g is acceleration due to gravity.

As diver dives out horizontally, his velocity is directed horizontally; that is, the initial vertical velocity is 0. So above equation becomes

h=\frac{1}{2} gt^2

Given, t =3 s.

Therefore,

h=\frac{1}{2}\times 9.8m/s^2(3\ s)^2 =0.5\times 9.8 m/s^2\times 9 s^2\\\\h=44.1\ m.

Now the horizontal distance of the diver to hit the water from base,  

=1.8\ m/s \times 3\ s=5.4\ m
