<span>Currents are one way in which water can flow globally. By traveling in these cyclical patterns, the water can move great distances across the planet, from one area of an ocean to another. A second way can be through the general water cycle. Through uptake (evaporation) and precipitation, the water can be dispensed large distances apart, as well.</span>

Hi everyone, I need help on the question: Why are humans the most dangerous creatures in the ocean

kozerog [31]

HUMAN ACTIVITIES ARE threatening the health of the world's oceans. More than 80 percent of marine pollution comes from land-based activities. From coral bleaching to sea level rise, entire marine ecosystems are rapidly changing.

Global warming is causing sea levels to rise, threatening coastal population centers. Many pesticides and nutrients used in agriculture end up in the coastal waters, resulting in oxygen depletion that kills marine plants and shellfish. Factories and industrial plants discharge sewage and other runoff into the oceans. Oil spills pollute the oceans, though U.S. water-sewage treatment plants discharge twice as much oil each year as tanker spills. Air pollution is responsible for almost one-third of the toxic contaminants and nutrients that enter coastal areas and oceans. The United Nations Food and Agriculture Organization estimates that 31.4 percent of fish stocks are either fished to capacity or over-fished.

A 75 A resistor in a circuit has a current flowing through it of 2.0 A. What is

Reptile [31]

Answer:

The power dissipated by the resistor can be calculated as $P = I^{2} R$ .

Explanation:

Joules heating law states that any conductor passed with the electric current produces heating effect which is the electric power loss.

The given circuit has, $R = 75 ohm$ resistor (the unit is wrong i question because resistor's unit is ohm not Ampere).
Current flowing through the circuit is $I = 2.0 A$ .

By using joules heating theory, $P = I^{2} R$ ,

$or,$ $P = 2^{2} * 75$

$or,$ $P= 4*75$

$or$ , $P= 300 W$ .

So the power dissipated by the resistor in the circuit is 300 W.

In the desert air, sound travels at 358 meters per second (m/s). In the polar air, sound travels at 330 meters per

Sati [7]

Answer:

The correct option is;

C. The temperature of the air affects the speed of sound

Explanation:

The information given are;

The speed with which sound travels in the desert air = 358 m/s

The speed with which sound travels in the polar air = 330 m/s

The major difference between the desert air and the polar air is that the temperature of the desert air is hotter than the temperature of the air in the polar region. Therefore the speed of sound is affected by the air temperature.

The equation that gives the relationship of the speed of sound in air, $v_{air}$ , to temperature is presented as follows;
