I think it most likely burn since th metal tube is going to transfer so much heat
Answer:
Systematic errors.
Explanation:
The density of the aluminium was calculated by a human and this is not natural but can be due to errors in the calibration of the scale for measuring the weight or taking readings from the measuring cylinder.
Random errors are natural errors. Random errors in experimental measurements are caused by unknown and unpredictable changes in the experiment. Systematic errors are due to imprecision or problems with instruments.
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.
Answer:
(a) A+B = 2i-3j
(B) A-B = 4i + j
Explanation:
We have given two vectors A = 3i-j and B = -1-2j
We have to find the two vectors that is A+B and A-B
(A) In first art we have calculate A+B for this we have to add simply vector A and v ector B
So A+B = 3i-j-i-2j = 2i-3j
(B) In this part we have to find A-B for this we have to simply subtract B from A so A-B = 3i-j-(-i-2j) =3i-j+i+2j =4i+j
Answer:
208m
Explanation:
since the angle is with the ground which gives a horizontal component to the velocity = v(cos)30°
so the velocity equals 40(cos)30°= 34.64m/s
range(distance) = speed × time
34.64m/s × 6s = 207.8m = 208m
