Well, if you are moving forward in a direction, then your velocity is your speed with the direction you are moving in. To calculate velocity, you divide your distance traveled by the time it took to travel that distance and you add your direction to it.
So to conclude, 300/100= 3 m/s South
The answer is D.
The air inside the bubbles is gas and the solid forms the bubble.
Answer:
3H2SO4 + 2B(OH)3 -> B2(SO4)3 + 6H2O
Explanation:
Answer: You can increase the weight, then test the speed, and make the weight normal and test the speed, and mark which one travels faster.
Explanation: This would test your hypothesis by comparing the speeds of the cars when more mass is added. Calculating the difference of the speed with more mass, and the speed with normal mass would give you your answer. A positive number would prove your hypothesis and a negative number would disprove it.
Here we have to choose the way which is not the common way to judge the quality of the air in a particular area.
The measuring the amount of precipitation in the area is not the common way to determine air quality in an area.
The acidity of the rain causes due to the excess amount of CO₂ and SO₂ in an area. Both the gases cause pollution.
The measuring of the amount of a particular gas element is a renowned way to determine the pollution level of an area.
The ozone is a harmful gas so the measuring of its amount in ground level can identify the level of pollution in the particular area.
