**URGENT** Now lets look at a skydiver who jumps out of a plane that has a forward velocity of 40 m/s. ignore air resistance. Af

If there's no air resistance, then the diver keeps moving horizontally at 40 m/s, even after s/he jumps out of a perfectly good airplane.

Also, gravity ADDS 9.8 m/s of downward speed for every second the diver falls.

One second after leaving the airplane, the diver is moving horizontally at 40 m/s, and moving vertically downward at 9.8 m/s .

The question asks for the "downward velocity".  That's 9.8 m/s .


The diver's TOTAL velocity is

                       √ (40² + 9.8²)

                   =  √ (1,600 m²/s² + 96.04 m²/s²)

                   =  √ (1,696.04 m²/s²)

                   =        41.2 m/s  in some direction between
                                           straight forward and straight down.

____ is the thermal energy transfer that occurs from the motion of fluid in a liquid or gas.
Marysya12 [62]
The answer is C. Convection.

Radiation is the transfer of energy through electromagnetic waves. Conduction, on the other hand, is energy transfer through solid material. Condensation occurs when warm gas makes contact with a cold surface or environment, which causes a change in state from gas to liquid. These definitions rule out choices A, B, and D. 

Convection is movement of particles in fluid or gas. As liquid/gas heats up, it becomes less dense and rises, moving away from the heat source. When it rises, it eventually cools down and sinks again. It is warmed up again and the cycle continues. This is why there is a circular motion when convection occurs.

umka21 [38]

Answer:

The funda mental frequency of the original tube is 182Hz.

Explanation:

See the attachment for the calculation steps.

In order to calculate the fundamental frequency of the original closed tube we need to find the length of the tube which is equal to the sum of the lengths of the two new tubes.

For closed tubes

f = nv/4L (n = 1, 3, 5,...n)

f = nv/2L (n = 1, 2, 3,...n)

The details of calculation can be found below in the attachment.
