By the information provided we can find the cars speed.
Explanation:
Speed is the distance traveled by any object in certain time. As we have distance traveled by car as 30 miles.
And time taken by car to travel 30 miles is half an hour. So speed is easily calculated as, .
Velocity is a vector quantity so we cannot determine velocity by knowing only distance and time, we need additional information of direction to know cars velocity.
Boyle's law says that the volume of a gas varies inversely with the pressure. When the volume of a certain gas is 4l , the pressure is 720 kpa (kilopascals). What is the pressure when the volume is 10l ?
The shaking produced by a
magnitude 8 earthquake is 3000 times greater than a magnitude 5 earthquake
using a Richter scale. The answer is letter C. As the number in the Richter
scale increases, the magnitude of earthquake also increases.
