A Chinook salmon can jump out of water with a speed of 6.70 m/s6.70 m/s . How far horizontally dd can a Chinook salmon travel th
aksik [14]

Answer:

R = 3.88 m

Explanation:

As the Chinook salmon leaves the water till it gets back into the water it is performing a projectile motion with the following parameters:

V₀ = Launch Speed = 6.7 m/s

θ = Launch Angle = 29°

R= Range of Projectile= Horizontal Distance Covered by Chinook salmon= ?

The value of the range of a projectile is given by the following formula:

R = (V₀² Sin 2θ)/g

R = [(6.7 m/s)² Sin {(2)(29°)}/(9.8 m/s²)]

R = [(6.7 m/s)² Sin (58°)/(9.8 m/s²)]

<u>R = 3.88 m</u>

6. Name two ways in which Faraday's work affects your own life in the twenty-first century.<br><br>​
Gekata [30.6K]

He discovered electromagnetic induction

He found a way to cause an electric current, and that discovery was later applied to many devices we use today.

His inventions transformed the home, farm, and factory

. Electricity eliminated manual labor like pumping water, so that rural families no longer spent hours of their day hauling water to livestock or to the house. Automated systems for tasks like milking cows kept farmers from crippling their hands, and the threat of barn fires from knocked over oil lamps during early-morning milking decreased.

12. The Copernican model of the universe was supported by A. Brahe and Kepler. B. Ptolemy and Brahe. C. Kepler and Einstein. D.
Rom4ik [11]

Answer:

A. Brahe and Kepler

Explanation:

The Copernican model was a heliocentric model of the universe. Copernicus thought that the Sun is stationary, and the Earth and the other planets are orbiting around it. He also noted that the stars are further away from the Sun compared to the distance between the Earth and the Sun. Three very important hings in his theory are that he thought that the Earth rotates around its own axis, revolves around the Sun, and has annual tilting of its axis. At some things, Copernicus was right with his theory, at some he wasn't, but anyway he made one giant step forward in the understanding of the universe. His theory was supported by many, though mostly after his death, with one of the most noticeable supporters of him being Ticho Brache and Kepler who made model of his theory, as well as improving it.
