If you are swimming upstream (i.e., against the current), at what speed does your friend on the shore see you moving?

Answers

Answer 1
Could be very slow since they’re basically going against the current which is hard so will be going slow

what is the frequency of a ocean wave that is traveling at a speed of 45 m/s if it has a wavelength of 3 meters? please show work

Answers

Answer:

15 miles per hour

Explanation:

45/3=15

Answer:

15 Hz or Hertz

Explanation:

To find the frequency of a wave, divide the velocity by the wavelength.

f=velocity/wavelength

We know the ocean wave is traveling at 45 meters per second, and it has a wavelength of 3 meters. Therefore, the velocity is 45 m/s and the wavelength is 3 m.

velocity=45

wavelength=3

Substitute these values into the formula.

f=45/3

Divide 45 by 3

f=15

Add appropriate units. Frequency uses Hertz or Hz.

f=15 Hertz

The frequency of the ocean wave is 15 Hertz.

What two charges could increase electrical force between objects

Answers

Answer:

From Coulomb’s Law of electrostatics the force of attraction or repulsion between two charged bodies is inversely proportional to the square of the distance between their two centers.

If the distance between them is doubled then the force is one-fourth of the original force.

If the distance between them is halved then the force is four times than the original force.

Planters moved from the Old South to the Deep South to: On April 20, 2010, an explosion on the Deepwater Horizon Macondo oil well drilling platform released 4 million barrels (636,000 cubic meters) of oil into the Gulf of Mexico. It took scientists and engineers nearly three months and several different attempts to cap the well. The Macondo oil well was located 1524 m (5000 feet) below the surface of the water, about 80 km (50 miles) off the coast of Louisiana. The spill affected 2113 km (1300 miles) of shoreline along the coasts of five states. Most crude oil contains 8487% carbon by weight. Scientists have not yet fully assessed the environmental impact of the accident.Computer modeling can be used to help improve cleanup and response systems for the next major oil spill. Which of these uses demonstrates how computer modeling can be used to minimize the impact of another spill? aCreating a model of how the oil spread through the Gulf of Mexico to predict what areas need the greatest amount of protection. bCalculating the total oil that entered the Gulf of Mexico during the spill. cRecording the number and type of each dead organism collected during the spill. dFinding the average flow rate of the oil through the burst pipeline during the spill. two specific reasons that the serial comma should be used in your writing.
