The formula for average speed is,
S= Total Distance Covered / Total Time Taken
In the given problem,
The total distance covered is 162 miles.
Since only the times are given, we have to determine how many hours did the car traveled from 7:30am to 10:30am.
To get the number of hours: First, subtract the hours, then the minutes. Hours: 10-7=3
Minutes: 30-30=0
Therefore,
S = 162miles/3hrs
S = 54miles/hr
The average speed of the car is 54miles/hr.
It would be d and c hoped i helped!
The concept of Archimedes' principle is that an object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. The fluid displaced has a weight W = mg, where g is acceleration due to gravity. Therefore, the weight of the displaced fluid can be expressed as W = ρVg.
Explanation:
When treating the electron as a wave, the concept of electrons orbiting the nucleus allows for the distinct energy levels.The diameter of electron orbits matches the orbit radii which also discrete the energy levels.
The small number of deflected particles were repelled from powerful heavy positively charged central cores which is known as the atomic nucleus.
The instrument that measures wind is called anemometer. Anemometer not only measures wind, but also, this measures the direction of the wind. And anemometer is also a common device used in a station weather. It is dervived from the greek work anemos which means wind.
