A cd player has a current of 0.1 a flowing through it. if the source voltage is 4v, what is the resistance? R=V/I

Physics
1 answer:
Effectus [21]3 years ago
4 0

Given parameters:

Current of CD player  = 0.1A

Source Voltage = 4V

Unknown:

Resistance  = ?

Solution:

Based on Ohm's law;

           V  = I R;

  V = voltage

   I = current

   R = resistance

Input the parameters and solve;

          4 = 0.1 x R

              R  = \frac{4}{0.1}   = 40ohms

The resistance of the CD player is 40ohms

A water bath in a physical chemistry lab is 1.55 m long, 0.710 m wide, and 0.570 m deep (high). If it is filled to within 3.55 i
Lesechka [4]

Answer:

528 liter.

Explanation:

Volume of the tank(cuboid) = l*b*h

But volume of the water = l*b*h

Where

l= length of the tank

b = width of the tank

h = the length from the bottom of the tank,

3.55 in to m,

0.09017m

Length of the water in the tank = 0.570 - 0.09017

= 0.47983 m.

Volume = 0.47983*0.710*1.55

= 0.528 m3.

1 m3 = 1000 liter.

0.528 m3 = 0.528*1000

= 528 liter

Maslowich

Answer:

For areas marked X, Y, Z, X is attractive only, Y has a very small range, and Z is attractive and repulsive

Explanation:

Solution

Given that:

From the question stated, Anna drew a diagram to compare forces that are strong and weak.

Now,

We are to find which labels are grouped in areas marked as X, Y, Z respectively.

Thus,

For X, Y, Z it is marked as:

X: Always attractive  or attractive only

Y: Very small range

Z:  Repulsive and attractive
