hope this helps :)
To solve this problem we will apply the concepts of Pythagoras to find the net path. An easy way is to graph the path to trace the path, which resembles that of a right triangle. The information provided is equivalent to that of the two short sides of the triangle, so we will find the longest side by the Pythagorean theorem. In this way,
Therefore the magnitude of the hummingbird’s total displacement is 3.12m

Answer:
1. Weight
2. potassium chlorate
3. pushing forward
Explanation:
1. Our full body stands in our feet, so feet takes all the weight of the body. In Newtonian mechanics, weight is a force. Weight is happened with the interaction between the mass and gravitational field. As the gravitational field is a vector, it has directions that are downward. So the interaction between mass and gravitational field works downward. So all the weight is felt by our feet.
2. In a fire stick, potassium chlorate is used. Potassium is known as a flammable chemical. Potassium chlorate is used in the upper part of the fire stick. When potassium chlorate faces frictions, a chemical reaction is happened, which creates great heat. The heat makes extra oxygen and heat, which makes the stick burn and create fire.
3. It is easy to rolling than push forward. If we consider a heavy lawn roller, the weight of the roller works downward. If we push the lawn roller, the force divided into two sub forces. One works downward which increases the weight of the roller and other works forward. But if we roll the lawn roller, the forces divided into two forces: upward and forward. Upward force makes the weight decrease and forward force makes it move forward. As the weight decrease, it becomes easy to roll than push
Answer:
It takes 10.5 minutes to kill all the bacteria.
Only 1 cell would remain after 9 minutes.
Explanation:
It will take 1.5 minutes to kill 90% of the cells. So, after 1.5 minutes, only 10% would remain. After 3 minutes, only 1% remain. So, to figure out how long it would take to kill a million cells, we have to multiply 1 million by 0.1 repeatedly until the final value is less than 1 that is because when the value is less than 1, it means there are no more bacteria.
So:
= 0.1
So, you need 10.5 minutes of killing to kill one million cells.
Time taken= 7 x 1.5 minutes = 10.5 minutes.
After 9 minutes you would have:
= 1 cell left
