Answer: 22 batches.
Explanation:
Given that 11 kg is a familiar weight for a bag of flour. Also, it is given that It takes 500 g of flour to make one batch of cookies.
How many batches of cookies can you make with one bag of flour
Let's first convert 11 kg into grams (g) by multiplying it by 1000
11 × 1000 = 11000 g
Divide 11000 by 500
11000/500 = 22
Therefore, 22 batches of cookies can be made with one bag of flour.
Answer:
The balloon will go to the back of the car.
Explanation:
A balloon filled with helium is much lighter than regular air, so the surrounding air is denser. After that, it has a lot to do with the motion of air in the car. Air pressure shifts whenever you press the break or accelerate, and the balloon will move accordingly. By moving the opposite you would. Because you're heavier than air.

Answer:
c. 981 watts
![P=981\ W](https://tex.z-dn.net/?f=P%3D981%5C%20W)
Explanation:
Given:
- horizontal speed of treadmill,
![v=100\ m.min^{-1}=\frac{5}{3} \ m.s^{-1}](https://tex.z-dn.net/?f=v%3D100%5C%20m.min%5E%7B-1%7D%3D%5Cfrac%7B5%7D%7B3%7D%20%5C%20m.s%5E%7B-1%7D)
- weight carried,
![w=588.6\ N](https://tex.z-dn.net/?f=w%3D588.6%5C%20N)
- grade of the treadmill,
![G\%=10\%](https://tex.z-dn.net/?f=G%5C%25%3D10%5C%25)
<u>Now the power can be given by:</u>
![P=v.w](https://tex.z-dn.net/?f=P%3Dv.w)
(where grade is the rise of the front edge per 100 m of the horizontal length)
![P=981\ W](https://tex.z-dn.net/?f=P%3D981%5C%20W)
