There are 20 apples in a box. What is the rule that gives total number of
apples, given the number of boxes in it
Answers
Step-by-step explanation:
This is a simple but tricky as well.
You can do this by giving each apple to 19 of them and giving the last i.e, 20th apple to the last child along with the basket.
In this way all children are satisfied, as they got an apple each and there's a apple still remaining in the basket.

Answer:
The driver of a 2.0 × 103 kg red car traveling on the highway at 45m/s slams on his brakes to avoid striking a second yellow car in front of him, which had come to rest because of blocking ahead as shown in above Fig. After the brakes are applied, a constant friction force of 7.5 × 103 N acts on the car. Ignore air resistance.
(a) Determine the least distance should the brakes be applied to avoid a collision with the other vehicle?
(b) If the distance between the vehicles is initially only 40.0 m, at what speed would the collision occur?
(c) Write your conclusive observations on the result obtained from this numerical. i.e. the importance of Physics in daily life.
