Answer:
D) Dalton's theory had repeated observations which were supported by extensive evidence.
Explanation:
Dalton had a basis for this prediction and theory. He worked extensive on gases before stepping forward with the Dalton's atomic theory.
His scientific conjecture was highly corroborated with a wide array of experimental evidence and many infallible proofs.
- Science is a logical way of reasoning that follow methodological approaches.
- It deals with empirical experimental proofs that must have been gathered and the veracity ascertained.
- Dalton during his time presented the scientific community with a pool of observations balanced with experimental evidences he accumulated with time.
<span>#1. A car moving at the rate of 65 miles per hour passes a truck
moving in the same direction at 38 miles per hour.
The speed of the car from the truck's frame of reference is
27 miles per hour.
#2. The X-43 is the fastest aircraft ever. It flew a distance of 3,961 km
from Los Angeles to New York at the speed of 11,265 km/h.
It took the X-43 (3,961 km) / (11,265 km/h) = 0.352 hour, or 21min 5.8sec
to fly that distance?
#3. A mail carrier walked six blocks to the north one block to the east ,
and then six blocks to the south.
After these three moves, the mail carrier's displacement is one block
to the East.</span>
La velocidad del buzo es de 7.04 m/s, 8.84 m/s y 2.27 m/s respectivamente.
<h3 /><h3>Velocidad
</h3>
La velocidad es la relación entre la distancia total recorrida y el tiempo total empleado. Está dado por:
Velocidad = distancia/tiempo
Para 10m de altura:
- Velocidad = 10 m/1.42 s = 7.04 m/s
Para 3m de altura:
- Velocidad = 3 m/0.78 s = 3.84 m/s
Para 1m de altura:
- Velocidad = 1 m/0.44 s = 2.27 m/s
La velocidad del buzo es de 7.04 m/s, 8.84 m/s y 2.27 m/s respectivamente.

Answer:
Momentum, 
Explanation:
Given that,
Mass of a mosquito, m = 0.000015 kg
Velocity of the mosquito, v = 5.2 m/s
We need to find the momentum of the mosquito. The momentum of an object is given by :
p = mv
Put all the values in the above formula.
So, the momentum of the mosquito is 
.
