Answer:

d

Explanation:

Resistance is given by

R = pL/A

Where A is length of wire , A is Area and p is resistivity of the material

From the expression above,

Resistance is affected by length and Area which means in consonance it's affected by the shape because shape affects the length and surface Area and Offcourse the size; the larger the surface area the Lower the resistance and the smaller the length and conversely the smaller the surface area and longer the length.

The physical state refers to the temperature of the substance. The higher the temperature the more electrons are free to move around and the lower the resistance.

Hence none of the option to a-c apply.

A 7.30 kg sign hangs from two wires. The
Alex

Answer:

28.0\; {\rm N} to the right.

Explanation:

Since the sign is not moving, the net force on this sign should be 0\; {\rm N}. For that, the horizontal component (x-component) of external forces on this sign should be 0\; {\rm N}.

Sources of external forces on this sign include tension from the wires, as well as gravitational pull (weight) from the earth. The gravitational pull from the earth is entirely vertical (y-component,) with a magnitude of 0\; {\rm N} in the horizontal direction. Thus, the only external forces on this sign in the x-component would be from the two wires.

The question states that the x-component of the force from the first wire is 28.0\; {\rm N} to the left. Thus, for the net force in the x-direction to be 0\; {\rm N}, the force from the other wire in the x\!-component needs to be 28.0\; {\rm N}\! to the right (same magnitude but opposite direction.)

A 5.22×104 kg railroad car moves on frictionless horizontal rails until it hits a horizontal spring stopper with a force constan
In-s [12.5K]

To solve this problem we will apply the principles of conservation of energy, for which we have to preserve the initial kinetic energy as elastic potential energy at the end of the movement. If said equality is maintained then we can affirm that,

\text{Initial Energy}=\text{Final Energy}

\frac{1}{2} mv^2=\frac{1}{2} kx^2

Here,

m = mass

k = Spring constant

x = Displacement

v = Velocity

Rearranging to find the velocity,

mv^2 = kx^2

v^2 = \frac{kx^2}{m}

v = \sqrt{\frac{kx^2}{m}}

Our values are,

m = 5.22*10^4kg

k = 4.58*10^5N/m

x = 32cm = 0.32m

Replacing our values we have,

v = \sqrt{\frac{(4.58*10^5)(5.22*10^4)}{0.32}}

v = 2.733*10^5m/s

Therefore the velocity is 2.733*10^5m/s

A tiny pig is dropped from the top of a building and lads safely on a trampoline. The tiny pig will have an increase in what typ
solmaris [256]

Answer:

The kinetic energy will have an increase as it falls.

Explanation:

The energy of a particle falling freely will be the sum of its kinetic energy and its potential energy.

When the pig is just dropped, the total enrgy will be only its potential energy. As it falls down its stored potetial energy will be converted into kineitic energy. Just before it touches the trampoline its total energy will be solely kinteic energy.

Thus, the kinetic energy will have an increase as it falls.
