Answer:
159HZ A
Explanation:
frequency= speed/wavelength
frequency= 342/2.15=159HZ
If an object's first movement is 3.0m North and another movement is 4.0m west, the magnitude of the overall displacement made would be 5.0 meters in the northwest direction.
<h3>What is displacement?</h3>
Displacement is a vector quantity. This indicates that it has both a direction and a magnitude and that it is visually represented as an arrow that points from the starting position to the ending position.
As given in the problem if an object's first movement is 3.0m North and another movement is 4.0m west
Resultant displacement can be calculated with the help of the triangle law of the vector addition,
Resultant = √( 3² + 4²)
=√25
= 5.0 m
Thus, the magnitude of the overall displacement made would be 5.0 meters in the northwest direction.

<span>A cart travels down a ramp at an average speed of 5.00
centimeters/second. What is the speed of the cart in miles/hour? </span>
To solve this problem we have set the conversion values to
determine the product during the conversion process.
<span><span>
1. </span>1

<span><span>
2. </span><span> 1 hour = 60 minutes</span></span>
<span><span>3. </span><span> 1 minute = 60 seconds</span></span>
Thus, we shall have
<span><span>1. </span>5 cm x 0.00000621371
mile/1cm = 0.000031069 mi</span>
<span><span>2. </span>0.000031069
seconds x 1 hr / 3600 = 0.111846815 miles / hr</span>
Answer: Troposphere
Explanation:
Fairly over the "surface" of Uranus lies the troposphere, where the atmosphere is the densest. The temperature ranges from a minus 243 degrees Fahrenheit (minus 153 degrees Celsius) to minus 370 F (minus 218 C) , with the upper regions being the coldest. This makes the atmosphere of Uranus the coldest within the solar system. Inside the troposphere are layers of clouds — water clouds at the least weights, with ammonium hydro sulfide clouds over them. Alkali and hydrogen sulfide clouds come following. At long last, lean methane clouds lay on the best. The troposphere amplifies 30 miles (50 kilometers) from the surface of the planet.
Using this information, we can determine that the Troposphere is the densest layer of Uranus's atmosphere.
