Answer:

500000000 lbft/s

Explanation:

F = Force or weight = 1000000 lbf

s = Displacement = 10000 ft

t = Time taken = 20 seconds

Work done is given by

W=Fs\\\Rightarrow W=1000000\times 10000\\\Rightarrow W=10000000000\ lb-ft

Power is given by

P=\dfrac{W}{t}\\\Rightarrow P=\dfrac{10000000000}{20}\\\Rightarrow P=500000000\ lbft/s

One Saucer power is 500000000 lbft/s

A car is on a circular off ramp of an interstate and is traveling at exactly 25 mph around the curve. Does the car have velocity
netineya [11]

Answer:

The car has velocity and acceleration but is not decelerating

Explanation:

Since the car is traveling at 25 mph around the curve, it has a tangential velocity. This tangential velocity is constantly changing in direction (so the car could adapt to the curve and not moving forward in a straight line), there should be a centripetal acceleration in play here. This acceleration does not slow down the car so it's not decelerating.

The viscosities of several liquids are being compared. All the liquids are poured down a slope with equal path lengths. The liqu
Vladimir [108]

Answer:

Move slowly and reach bottom later.

Explanation:

Viscosity is termed as the thickness or consistency of any liquid or semi liquid. It is related to the internal friction of the substance.

When several liquids are poured down with equal path lengths then the liquid will high viscosity will reach the bottom latter while one with less viscosity.

The internal friction of the molecules tends to keep them together making its consistency more thick. Thus when it will slope down from a certain height it will take more time to reach down.

The characteristic that gives an element its distinctive properties is its number of:_________
oee [108]

The characteristic that gives an element its distinctive properties is its number of protons because the number of protons of any element represents its atomic number.

<h3>What is the atomic number?</h3>

The total number of protons present in an atom is known as the atomic number of that atom. The atomic number has no correlation either with the number of neutrons or the number of electrons present inside an atom.

Since the number of protons in any element corresponds to its atomic number, this property provides an element with its particular features.
