I believe the answer is C or A but I’m not sure
<u>Answer:</u>
The modern atomic theory has given by "John Dalton and framed postulates".
<u>Explanation:</u>
The fundamental role of atoms in chemistry is established by the modern theory of atoms mentioned in 1808 for the first time by an English scientist named John Dalton. This consists of three sections such as all matter is composed of atoms, atoms of the same element are the same while atoms of different elements are different, atoms combine to form compounds in full-number ratios.
The unique characteristic of the "number of protons" is that all atoms of the same compound share. While the atoms of the same element i.e having a similar number of protons can have different numbers of neutrons and such elements are called isotopes.
Answer:
112 m travelled
Explanation:
a divided 56 m / s by 60 and then multiplied it by 120
Answer:
see below
Explanation:
according to newton's second law of motion,
F = MA
where F is the resultant force
m is the mass
a = acceleration
so suppose the mass of the bowling ball is 10 kg
and the mass of golf ball is 1 kg
and the force applied on both of them is 5 N
substitute the values in the formula
for the bowling ball
5 = 10 x a
a = 0.5 ms²
for the golf ball
5 = 1 x a
a = 5 ms²
so which accelerated more the golf ball right?
so last option is the answer

Answer:
56250 N
Explanation:
mass, m = 6000 kg
initial speed, u = 20 m/s
final speed, v = 5 m/s
distance, s = 20 m
Use third equation of motion
5 x 5 = 20 x 20 + 2 a x 20
25 = 400 + 40 a
a = - 9.375 m/s^2
Braking force, F = mass x acceleration
F = 6000 x 9.375
F = 56250 N
