A peregrine falcon can travel 537,600 furlong/fortnight. A race car travels 212ft/s. A spider can jump with a maximum velocity o
o-na [289]
Convert everything to one base unit (let's do ft/s in this case)
There are 660 ft in a furlong and 2 weeks or 1209600 seconds in a fortnight
Multiply 537,600furlong and 660 ft/furlong and divide by 1209600 to get 293.333ft/s

The race car is already in ft/s

There are 30.48 cm in 1 foot and 3600 seconds in 1 hour.  Multiply 9,000,000 by 1/30.48 and 1/3600 to get 82.02ft/s

THe peregrine falcon is the fastest

Which is the more preferred fuel: one with a higher energy density or one with a lower energy density
Nana76 [90]

The higher the energy density of a fuel, the greater the amount of energy it has stored.

<h3>What is the energy density?</h3>

The energy density of a fuel is defined as the amount of energy it possesses per unit volume or per unit weight.

<h3>Characteristics of the energy density</h3>

  • It is the amount of energy accumulated in an energy vector per unit volume or mass.

  • In general, higher density energy sources and carriers are preferable, as many end uses require concentration of such energy.

  • The packaging of energy in liquid hydrocarbons is the one with the highest energy density, that is, the highest energy per volume unit, hence its high use in the transportation sector.

Therefore, we can conclude that in general, fuels, especially low molecular weight fuels, have high energy densities.

Which of the following is necessary for photosynthesis?
Amanda [17]

Answer:

A. Water

Explanation:

The formula for photosynthesis is carbon dioxide plus water which (with sunlight and chlorophyll) gets converted into glucose + oxygen, energy for the plant.

Without water, photosynthesis is unable to properly take place and plants are unable to produce the energy needed for them to continue maintaining life.
