Answer:
Shorter than(?)
Explanation:
What is it that you're looking for here? Is it just some random fill in the blank question?
My guess is that the horizontal distance has to be shorter than that of the ladder length because if it wasn't then the ladder would be laying down or maybe standing straight up... and you can't really use it normally like that... I'm sorry, where is the Physics in this question exactly?
consider the forward direction as positive and backward direction as negative. hence displacement in froward direction will be taken as positive and displacement in backward direction will be taken as negative.
= displacement in forward direction = 10 meters
= displacement in backward direction = - 5 meters
= net displacement
net displacement is given as
= +
= 10 + (- 5)
= 5 meters
Since net displacement is positive , and forward is positive direction of motion.
hence the displacement is 5 meters in forward direction.
b)
d₁ = distance traveled in forward direction = 10 meters
d₂ = distance traveled in backward direction = 5 meters
D = total distance traveled
total distance traveled is given as
D = d₁ + d₂
D = 10 + 5
D = 15 meters
Answer:
Collision theory is used to predict the rates of chemical reactions, particularly for gases. It is based on the assumption that for a reaction to occur for the reacting species (atoms or molecules) must come together or collide with one another. Not all collisions, however, bring about chemical change.
If two molecules collide with sufficient activation energy, there is no guarantee that the collision will be successful. In fact, the collision theory says that not every collision is successful, even if molecules are moving with enough energy. The reason for this is because molecules also need to collide with the right orientation so that the proper atoms line up with one another, and bonds can break and re-form necessarily.
The answer is SALIVA Carbohydrate digestion starts in the mouth and protein digestion starts in the stomach. The digestive system fuels the cells and the excretory system rids the body of the cells' waste.
