If the torque required to loosen a nut holding a wheel on a car is 48 N · m, what force must be exerted at the end of a 0.23 m l
Andreas93 [3]

Answer:

F = 318.1 N

Explanation:

As we know that torque to open the nut is given by formula

\tau = \vec r \times \vec F

so we can write it as

\tau = rFsin\theta

now we know that

\tau = 48 Nm

r = 0.23 m

angle between force and the wrench is 41 degree

so we have

48 = (0.23)Fsin41

F = \frac{48}{(0.23)sin41}

F = 318.1 N

sattari [20]

Answer:

D. independent; dependent

Explanation:

The dependent variable is the variable that is being measured during the course of an experiment. It represents the variable that changes with the manipulation of other variables.

The independent variables are variables which are varied or manipulated during the course of an experiment. The effects of their variations are measured on the dependent variable.

<em>In this case, the interval between the bell and presentation of food was varied and the effects of the variation was measured by determining the amount of salivation.</em>

Hence, the interval is the independent variable and the amount of salivation is the dependent variable.

The correct option is D.

Imagine a universe in which, like in ours, there are two kinds of charges (positive and negative), with the like charges repelli
GuDViN [60]

Answer:

the static charge is not always distributed on the surface of the conductor, there are also charges in the volume but of lesser magnitude

Explanation:

In this hypothetical system the electric force is of type

       F = k' \frac{q_1 q_2 }{r^2}

in this case the force decays to zero much faster,

if we call Fo the force of Coulomb's law

         F₀ = k \frac{q_1 q_2 }{r^2}

assuming the constant k is the same

the relationship between the two forces is

        F / F₀ = 1 / r

        F = F₀ / r

when analyzing this expression the force decays much faster to zero.

In an electric conductor, charges of the same sign may not feel any repulsive force from other charges that are at a medium distance, so there is a probability that some charges are distributed in the volume of the material, this does not happen with coulomb's law

Consequently, the static charge is not always distributed on the surface of the conductor, there are also charges in the volume but of lesser magnitude
