<u>Answer:</u>

   Displacement = 100 meter

   Distance covered = 180 meter.

<u>Explanation:</u>

   Let east represents positive x- axis and north represent positive y - axis. Horizontal component is i and vertical component is j.

  Carl runs 100 m West, Displacement = -100 i

  He then runs 60 m North, Displacement = 60 j

   He then runs 20 m East, Displacement = 20 i

  Total displacement of Carl's running = -100 i + 60 j + 20 i = (-80 i + 60 j) m (Vector)

  Magnitude of displacement =  \sqrt{(-80)^2+60^2} =100 m

  Distance traveled by Carl = 100 + 60 + 20 = 180 m ( Scalar)

A series circuit has two 10-ohm bulb is added in a series. Technician A says that the three bulbs will be dimmer than when only
ANTONII [103]

Answer:

Technician  A  is right. The situation will happens even with only two bulbs in series

Explanation:

We must take into account that

1.- All electric device need its nominal voltage to operate

2.-Any and all electric device means an electric load for the source in terms of equation that means any device will implies a drop voltage of V = I*R ( I the flows current and R  the resistance of the device)

3.-Nominal voltage for bulbs are specify for houses voltages you find between fase and neutral wires for instance in Venezuela 120 (v).

4.-In a imaginary circuit of only one bulb, the nominal voltage will be applied and the bulb will operates correctly, but when you add another bulb (in series) the nominal voltage will split  between the two bulbs ( we  could find a situation such as the first bulb work properly but the second one does not). The voltage split according to Ohms law (in such way that the sum of voltage between the terminal of the first bulb plus the voltage at terminals of the second one are equal to nominal voltage.

For that reason all the bulbs are connected in parallel in wich case all of them will operate with the common voltage

He instruction booklet for your pressure cooker indicates that its highest setting is 11.1 psi . you know that standard atmosphe
blagie [28]

Given that,

Atmospheric Pressure = 14.7 psi

Cooking Pressure = 14.7 +11.1 = 25.8 psi

Take, Atmospheric Temperature = 25 °C

Cooking Temperature = ??

Since, we know that Gas equation is given by:

PV = nRT

or

P ∝ T

P1 / T1 = P2 / T2

14.7/ 25 = 25.8/ T2

T2 = 25*25.8/14.7

T2 = 43.87 °C

The cooking pressure will be 43.87 °C.

How much power does an electric device use if the current is 36.0 amps and the resistance is 3.9 ohms?
dsp73
<span>Question: How much power does an electric device use if the current is 36.0 amps and the resistance is 3.9 ohms? </span>

How?: 

Equation: P = I^2 R          

Meanings:
P = Power in Watts
I = Current in Ampere
R = Resistance in ohms.

Plugged in: P = 36^2<span> x 3.9 = 5054.4
 
Answer: P= </span>5100 watts.
