A wrench 0.500 m long is applied to a nut with a force of 80.0 N. Because of the cramped space, the force must be exerted upward

at an angle of 60.0° with respect to a line from the bolt through the end of the wrench. How much torque is applied to the nut?
1
14.2 N·m
34.6 N·m
20.0 N·m

Answer:

Torque, \tau=34.6\ N.m

Explanation:

It is given that,

Length of the wrench, l = 0.5 m

Force acting on the wrench, F = 80 N

The force is acting upward at an angle of 60.0° with respect to a line from the bolt through the end of the wrench. We need to find the torque is applied to the nut. We know that torque acting on an object is equal to the cross product of force and distance. It is given by :

\tau=Fr\ sin\theta

\tau=80\times 0.5\ sin(60)

\tau=34.6\ N.m

So, the torque is applied to the nut is 34.6 N.m. Hence, this is the required solution.

The element Ne, neon, has ____ (number) complete shells having its ____ electrons in second _____.
KatRina [158]

Answer:

2, 8 and shell

Explanation:

Neon as atomic number 10. Since for each shell, electrons equal 2n².

When n = 1, 2n² = 2(1)² = 2

When n = 2, 2n² = 2(2)² = 8

So it fills both the first and second shell with 2 and 8 electrons respectively to achieve its stable atomic state. The rest of the 8 electrons go into the second shell because the first shell has achieved its stable dual configuration of two electrons. The next shell requires a maximum of 8 electrons to achieve stability so, the remaining electrons fill it up to achieve the stable octet configuration.

Which of the following examples could this free body diagram describe? (Check all that apply)
boyakko [2]

Answer:

A car accelerating to the right

Explanation:

The free-body diagram shows all the forces acting on an object. The length of each arrow is proportional to the magnitude of the force represented by that arrow.

In this free-body diagram, we see that there are 4 forces acting on the object, in 4 different directions. We also see that the two vertical forces are equal so they are balanced, while the force to the rigth is larger than the force to the left: this means that there is a net force to the right, so the object is accelerating to the right.

Therefore, the correct answer is:

A car accelerating to the right

At t = 0 a car has a speed of 30 m/s. At t = 6 s, its speed is 14 m/s.
Hitman42 [59]

Answer:

-2.67 m/s²

Explanation:

a = Δv / Δt

a = (14 m/s − 30 m/s) / (6 s − 0 s)

a = -2.67 m/s²

3. If you put flowers in water through what process does the water enter the steams ?
worty [1.4K]

Water travels through long, thin tubes running up from the roots through the stems and leaves called xylem.Water moves up the xylem through a process called capillary action.

Capillary action allows water to be pulled through the thin tubes because the molecules of the water are attracted to the molecules that make up the tube. The water molecules at the top are pulled up the tube and the water molecules below them are pulled along because of their attraction to the water molecules above them.
