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.
Answer:
Explanation:
Given,
Mass of the steel = 19 g
height reached, h = 1.35 m
angle, θ = 35°
when the ball is projected vertically with initial velocity v.
Maximum height reached is equal to,
initial velocity,
v = 5.14 m/s
Hence , the maximum velocity is equal to 5.14 m/s
For projectile motion horizontal distance is given by
the horizontal distance travel by the ball is equal to
I would say a because i just had this
Answer:
7 rows of trees
If x equals the amount of rows...
8x = 56
Explanation:
8x = 56
(1/8) 8x = 56 (1/8)
x = 7
Answer:
First answer.
Explanation:
There may be a 5N force, but if the frictional force also equals 5N, than they cancel eachother out, resulting in the brick still staying still, as it is resting on a (perfectly) level surface, but any amount of force would make the brick move.
