is acting on an object that is constrained to move along the x-axis. If the force moves the object 3m, from the origin, what is

Snezhnost [94]

Answer:

U = - ∫ F dx

U = - 3F₀

Explanation:

Force and potential energy are related

F = $- \frac{dU}{dx}$

dU = - F dx

∫ dU = - ∫ F dx

U- U₀ = - ∫ F dx

to solve the problem we must know the form of the force, if we assume that F = F₀ and U₀ = 0 for x = 0

U = - F₀ 3

You live on a planet far from ours. "Based on extensive communication with a physicist on earth", you have determined that all l

Ugo [173]

Answer:

8.56 m/s2

Explanation:

Using law of energy conservation while taking into account of the rotational and translation kinetic energy, when the solid cylinder rolls down the incline we have the potential energy converted to kinetic energy:

$E_p = E_{kv} + E_{k\omega}$

$mgh = mv^2/2 + I\omega^2/2$

where m is the mass, $I = mr^2/2$ is the moments of inertia of the solid cylinder $\omega = v / r$ is the angular speed of the cylinder

$mgh = mv^2/2 + \frac{mr^2}{2}\frac{(v/r)^2}{2}$

$mgh = mv^2/2 + mv^2/4 = 3mv^2/4$

$h = 3v^2/(4g)$

So if you plot a liner chart of h vs $v^2$ and get a slope of 6.42 then that means 3/(4g) = 6.42 so $g = 6.42*4/3 = 8.56 m/s^2$

The gravitational acceleration on this planet is 8.56 m/s2

According to the __________perspective, people who suffer from PTSD are classically conditioned.

patriot [66]

According to the pavlovian perspective, people who suffer from PTSD are classically conditioned.

This is referred to as post traumatic stress disorder which is a mental disorder from a terrifying incident.

The pavlovian perspective however view this disorder as being a type of classical conditioned one.

House current is 120 volts. If a light bulb runs a current of 10 amps, what is the resistance?

nlexa [21]

Answer:

12 ohms

Explanation:

Ohm's Law tells the relationship between voltage, current, and resistance.

It can be written in three different ways, depending on which ones you know,

and which one you want to find.

Here's the one we need:

Resistance = (voltage) divided by (current)

= (120 V) / (10 Amp)

= 12 ohms .
