Answer:
1 False. Atoms can be divided, see case of radioactive materials
Explanation:
Dalton's theory says that matter is made up of very small particles called atoms that are indivisible and cannot be destroyed, chemical compounds are made up of atoms.
With this statement, we can review the proposals,
1 False. Atoms can be divided, see case of radioactive materials
2 True. Chemical reactions are performed by atoms.
3 True. This statement remains unchanged.
4 True. The compound or molecules are formed by atoms
Answer:
The answer to your question is: B. F = 45 N
Explanation:
Newton's second law of motion states that the acceleration of an object is directly proportional to the force exerted and inversely proportional its mass.
Data
F = ?
a = 3 m/s²
m = 15 kg
Formula
F = ma
Process
F = ( 15)(3)
F = 45 N
Let the key is free falling, therefore from equation of motion
.
Take initial velocity, u=0, so
.
As velocity moves with constant velocity of 3.5 m/s, therefore we can use formula
From above substituting t,
.
Now substituting all the given values and g = 9.8 m/s^2, we get
.
Thus, the distance the boat was from the point of impact when the key was released is 10.60 m.
Given info
d = 0.000250 meters = distance between slits
L = 302 cm = 0.302 meters = distance from slits to screen
= angle to 8th max (note how m = 8 since we're comparing this to the form )
(n = 5 as we're dealing with the 5th minimum )

There is a slight discrepancy (the first two results were 611 nm while this is roughly 613 nm) which could be a result of rounding error, but I'm not entirely sure.
