Explanation:

A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force.

A constant net torque is exerted on an object. Which of the following quantities for the object cannot be constant? (Select all

prohojiy [21]

Answer:

A. kinetic energy

B. angular velocity

E. angular position

Explanation:

The quantities that cannot be constant if a constant net torque is exerted on an objecta are:

A. Kinetic energy. If a torque is applied, the linear or angular speed will be changing at a rate proportional to the torque, so the kinetic energy will change too.

B. Angular velocity. It will change at a rate equal to the torque.

C. Angular position. If the angular velocity changes, the angular position will change.

Suppose you wish to fabricate a uniform wire from a mass m of a metal with density rhom and resistivity rho. If the wire is to h

slamgirl [31]

Answer:

Explanation:

Resistivity and resistance are proportional and depends of the length and the cross-sectional area of the wire:

$R=\frac{L}{A}\rho$

furthermore, the density is the mass divided by the volume, and the volume can be written as the area multiplyed by the length:

$\rho_m=\frac{m}{A*L}$

Now you have tw equations and two variables, so you can solve for each of them.

first, solve for A in both equations and replace them:

$\frac{L}{R}\rho=\frac{m}{\rho_mL}$

$L^2=\frac{mR}{\rho_m \rho} \\L=$

now replace this into any of the previous equiations:

$R=\frac{\sqrt{\frac{mR}{\rho_m \rho} } \rho}{A} \\A=\sqrt{\frac{mR\rho^2}{\rho_m \rho R^2} }\\A=\sqrt{\frac{m\rho}{\rho_m R} }$

If you assume the wire has circular cross-sectional area, then the area is:

$A=\pi(\frac{d}{2} )^2$

solving for d:

$d=2\sqrt{\frac{A}{\pi} }$

replacing A and simplifying:

$d=2 \sqrt[4]{\frac{m\rho}{\rho_m R \pi^2} }$

adelina 88 [10]

If you look at a white light bulb with red tinted sunglasses the lightbulb looks red because of the tint on the sunglasses the other colors are still there but you’re looking through red glasses so everything shows more red than any color. (If that makes sense)
