How To achieve the largest resistance ?

Physics
1 answer:
nadya68 [22]3 years ago
3 0

Answer:

material, eg copper, has lower resistance than steel.

length - longer wires have greater resistance.

thickness - smaller diameter wires have greater resistance.

temperature - heating a wire increases its resistance.

If 1 meter = 3.28 feet, what is the height of the Washington Monument in meters?
jasenka [17]
Since you didn't provide how tall the Monument was, I took the liberty to find it and it is 555 feet tall. So to convert to meters we must divide 555 by 3.28 or multiply it by 0.3048 (this is the method I used).
555 x 0.3048 = 169.164 meters

Find the current if 55 C of charge pass a particular point in a circuit in 5 seconds.
uranmaximum [27]

Answer:

<em>The current is 11 Amperes</em>

Explanation:

<u>Electric Current</u>

The electric current is defined as a stream of charged particles that move through a conductive path.

The current intensity can be calculated as:

\displaystyle I=\frac{Q}{t}

Where:

Q = Electric charge

t   = Time taken by the charge to move through the conductor

The current intensity is often measured in Amperes.

The charge passing through a point in a circuit is Q= 55 c during t=5 seconds, thus the current intensity is:

\displaystyle I=\frac{55}{5}

I = 11 Amp

The current is 11 Amperes

How does the equivalence principle lead us to suspect that spacetime might be curved?
Dafna11 [192]

Answer:

To understand Einstein's thought processes,

imagine yourself in the sealed box, being accelerated through interplanetary

space at 9.8m/s^2. You grab the flashlight that you keep on the bedside

table and shine a beam of light perpendicular to the acceleration vector. Since the box is accelerating upward, the path of the light beam

will appear to you to be bent downward, as the floor of the box rushes up

to meet the photons. However, thanks to the equivalence principle, we can

replace the accelerated box with a stationary box experiencing a constant gravitational acceleration. Since there's no way to distinguish between these

two cases, we are led to the conclusion that the paths of photons will be

curved downward in the presence of a gravitational field. Gravity affects

photons, Einstein concluded, even though they have no mass. Contemplating  the curved path of the light beam.

Fermat's principle, which states that

light travels between two points along a path which minimizes the travel time  required. In a vacuum, where the speed of light is constant, this translates  into the requirement that light takes the shortest path between two points.  In Euclidean, or flat, space, the shortest path between two points is a straight  line. However, in the presence of gravity, the path taken by light is not a  straight line. Thus, Einstein concluded, space is not Euclidean.  The presence of mass, in Einstein's view, causes space to be curved.
