A severe storm on January 10, 1992, caused a cargo ship near the Aleutian Islands to spill 29,000 rubber ducks and other bath to

Anna35 [415]

The distance that the rubber ducks traveled = 1600 miles.
The time taken to travel this distance = 10 months.

By definition, the approximate average speed of the ocean is
v = (1600 miles)/(10 months)

Note that
1 mile = 1609 m
10 months = (10 months)*(30 days/month) *(24 hours/day)
= 7200 hours (approx.)
= 7200*3600 = 2.592 x 10⁷ s

Therefore
$v = \frac{(1600 \, m)*(1609 \, \frac{m}{mi}) }{(10 \, months)*(2.592 \times 10^{7} \, \frac{s}{10 \, months}) } = 0.0993 \, \frac{m}{s}$

Also,
$v = \frac{1600 \, m}{7200 \, h} =0.222 \, \frac{mi}{h}$

Answer:
The average velocity is approximately 0.1 m/s, or 0.222 m/h.

How does water deposit sediment

uysha [10]

Erosion can move sediment through water, ice, or wind. Water can wash sediment, such as gravel or pebbles, down from a creek, into a river, and eventually to that river's delta. Deltas, river banks, and the bottom of waterfalls are common areas where sediment accumulates. i hope this answers your question

Ohm's law is represented by the equation I = V/R. Explain how the current would change if the amount of resistance decreased and

jok3333 [9.3K]

constant voltage of 100 volts and a resistance of 500 ohms.
<span>I = 100 / 500. Current = 0.2 amps </span>

<span> resistance to 200 ohms. I = 100 / 200. Now the current is 0.5 amps.</span>
As we also know that Voltage is directly proportional to the current
Resistance is the proportionality constant.

Two light bulbs, A and B, are connected to a 120-V outlet (a constant voltage source). Light bulb A is rated at 60 W and light b

d1i1m1o1n [39]

Answer:

Bulb A has a greater resistance.

Explanation:

Electric power (P) = V²/R

P = V²/R................ Equation 1

Where P = power, V = Voltage, R = Resistance.

Make R the subject of the equation

R = V²/P ................ Equation 2

For Bulb A,

Given: V = 120 V, P = 60 W.

Substitute into equation 2

R = 120²/60

R = 240 Ω

For bulb B

Given: V =120 V, P = 100 W.

Substitute into equation 2

R = 120²/100

R = 14400/100

R = 144 Ω

Hence Bulb A has a greater resistance.
