Explanation:

the wavelength of a oceans wave depends on the gravity from the moon and the wavelength . sometimes wavelengths are determined by the shapes of the orbits.

sometimes or most of the times wavelengths can also determine the size of the size of water molecules within a wave.

Alice is going on a picnic and is aware that it will be easier to carry the picnic basket if it balances at the center where the

Maksim231197 [3]

Answer: 13.703cm from the center of the basket on the end holding the 0.675kg package of hot dog.

Explanation:

The center of the basket is at point 26 cm from each end of the basket.

This is gotten from the evaluation;

52cm/2.

The principle of moments is very important in solving this problem,

"The algebraic sum of all clockwise moments must be equal to he algebraic sum of all anticlockwise moments"

The statement above is the principle of moments.

Now to the question,

Since the acceleration due to gravity is assumed to be equal for all of the masses,

By intuition, the basket would tilt downwards on the end which holds the 1.65kg container of potato salad.

Consequently, to balance the basket 1.85kg container of lemonade must be placed at a distance, x from the center of the basket along the length of the basket (on the end holding the 0.675 package of hot dog).

Therefore, Taking moments about the center of the basket,

(1.65kg×26cm)=(0.675kg×26cm)+(1.85cm×xcm)

Therefore from the expression above, x = 13.703cm from the center on the basket on the side which holds the 0.675kg package of hot dog.

PS: The knowledge of moments of forces is very important in understanding machines especially those which are used for measuring weights relative to other weights.

How to find distance when given mass time and force

Yuri [45]

Answer:

it is actually very easy & interesting. first write formula of force F=Mass×Acceleration . now see what are the unknowns , mass is known but acceleration is not . so find acceleration, a=velocity/time , but now again we dont know velocity, V= distance/time . subbing in all the values, Force=Mass×(distance/time^2)

Hope it helps if you have any problem feel free to ask.

Determine how many gallons of jet fuel the jet can hold and still be able to takeoff from sea level with an outside temperature

zysi [14]

Question:

For a certain commercial jet to be able to achieve liftoff, its total weight cannot exceed 333,390 kg. If the empty weight (i.e., no fuel or passengers) of the jet is 163,293 kg and there are 300 passengers aboard with an average weight of 75.0 kg, determine how many gallons of jet fuel the jet can hold and still be able to takeoff from sea level with an outside temperature of 277 K. The specific gravity of jet fuel is 0.804

Answer:

The answer to the question is;

The jet can hold 48642.2 gal or 40503 galUK of jet fuel and still be able to takeoff from sea level.

Explanation:

To solve the question, we note the following

Maximum total weight at liftoff = 333,390 kg

Mass of jet when empty = 163,293 kg

Average mass of one passenger = 75.0 kg

Number of persengers = 300

Total mass of persengers = 300×75 =22500 kg

Mass of jet + passengers = 163293 + 22500 = 185793 kg

Allowable mass jet carry = Mass of jet fuel

= Maximum total weight at liftoff - Mass of jet + passengers

= 333,390 kg - 185,793 kg = 147597 kg

Specific gravity of jet fuel = 0.804 therefore density of jet fuel is given by

Density of jet fuel = Density of water × The specific gravity of jet fuel

= 997 kg/m³ × 0.804 = 801.588 kg/m³

Volume of jet fuel = (Mass /Density) of the jet fuel = $\frac{147597 }{801.588}$ = 184.131 m³

However 1 m³ = 264.172 gal = 219.969 galUK

∴ 184.131 m³ = 264.172× 184.131 gal

= 48642.2 gal = 40503 galUK
