Calculating the average speed is simple using the formula <span>speed = distance/time</span>
Answer:
Chidera is the stronger individual pushing the box with a net force of 5N to the left.
Explanation:
Chidera is using more force meaning they are stronger and the net force is 5N because when you plug in the equation
F1 = 30 + F2 = -25 = 5N
you get 5N
Answer:
0.48 N/cm
Explanation:
The original length is 10cm so with a force of 10cm, the extension will be 12.2-10=2.2 cm when force of 1N is exerted. Similarly, with a force of 3N, the extension is 16.4-10=6.4cm
The slope will be given by change in force/ change in extension and this is equivalent to the stiffness.
Change in force is 3-1=2 N
Change in exgension is 6.4-2.2=4.2 cm
The slope will be 2/4.2=0.4761904761904 N/cm
Rounded off, the slope is 0.48 N/cm and this is the stiffness of the spring.
Answer:
1.)When you arrive from school and you smell cookies baking in the kitchen your brain will tell you that you are hungry and that you should go to the kitchen at that point your sense organs like your nose helps you to detect that something is baking(cookies)and your nervous system (brain)will tell you that you are hungry and it will command/direct your brain to go to the kitchen then for you to eat the cookies and drink the milk the digestive system is going go help you to chew,swallow and digest the food which has been taken and when you also run to the kitchen at the beginning your brain will direct your skeletal and muscular system because the skeletons and muscles work hand in hand,and when you finish your meal the body will circulate some nutrients or minerals from the food or snack taken to other parts of the body for energy.
2.)When you sleep the whole body is asleep except the heart which needs to continue circulating blood around the whole system and sometimes the brain may not rest when you are sleeping it may continue to do it's work that's why some people usually sleep walk or sleep talk,it means the brain is not at rest and still doing some things....Thank you for the question I hope it is very useful to you.
