Answer:

BASE jumping is the recreational sport of jumping from fixed objects, using a parachute to descend safely to the ground. "BASE" is an acronym that stands for four categories of fixed objects from which one can jump: building, antenna, span, and earth (cliff).[1][2] Participants exit from a fixed object such as a cliff, and after an optional freefall delay, deploy a parachute to slow their descent and land. A popular form of BASE jumping is wingsuit BASE jumping.

Explanation:

In contrast to other forms of parachuting, such as skydiving from airplanes, BASE jumps are performed from fixed objects which are generally much lower altitude, and BASE jumpers typically carry only one parachute. BASE jumping is significantly more hazardous than other forms of parachuting, and is widely considered to be one of the most dangerous extreme sports

Calculate the force constant (in N/m) of its plunger's spring if you must compress it 0.160 m to drive the 0.0540 kg plunger to

Leni [432]

Answer:1.318 kN/m

Explanation:

Given

compression $x=0.16 m$

mass of Plunger $m=0.0540 kg$

Top speed $v_{max}=25 m/s$

Conserving Energy

Elastic Potential Energy of spring stored converted in kinetic energy of Plunger

$\frac{1}{2}kx^2=\frac{1}{2}mv^2$

$k\times (0.16)^2=0.054\times 25^2$

$k=1318.35 N/m$

A plane progressive wave is represented by the equation y =2sin (2000πt- 0.5x) the symbols have their usual meanings. what is th

frutty [35]

The frequency of the wave is the frequency of that sine function ... 2,000π ... but that's the <u>angular </u>frequency, in radians per second.

To convert angular frequency to Hz, we have to divide by 2π.

So the frequency of this wave is <em>1,000 Hz. </em>

Is the the last half of the month waxing or waning( talking about moon phases

rewona [7]

Its not really definable. Say, you can have a full moon on the last day of November, and have the waning phases throughout the first half. Or you can have a new moon on the last day of December, and have the waxing phases during the first half of the month.

Explain your results: How can Earth’s gravity affect the water when the water isn’t actually touching the Earth? (2 pts) Do you

Levart [38]

Answer:

Because the Earth has so much gravity, it can hold water, land, and life in it's atmosphere.

(Not sure what beaker you are talking about, so sorry) But I don't think the moon's gravity would have an effect on a beaker of water because the Earth's gravity is much more than the moon's.

I think you would be able to feel a little bit of Earth's gravity on the moon because the Earth's gravity pulled the moon into orbit, therefore, gravity on Earth my have some effect on the moon.

hope this helps!
