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.
Answer:

Because that is when they're mind learns how to read
Space surrounding magnet is called the magnetic field. In this field we can encounter magnetic force. Magnet attraction occurs when poles are unlike and is caused by magnetic force. It means that poles should have opposite values.
Answer:
The ratio of the time he is above ymax /2 to the time it takes him to go from the floor to that height = 0.707
Explanation:
The mathematical derivation and steps is as shown in the attached file.
Answer:
Explanation:
a )
If it is totally absorbed pressure is calculated as follows .
Pressure = I / c where I is intensity of light falling .
= 1000 / 3 x 10⁸
= 3.33 x 10⁻⁶ N / m²
b ) weight of tritium atom
= 3 x 1.67 x 10⁻²⁷ kg
acceleration = force / mass
= 3.33x 10⁻⁶ / 3 x 1.67 x 10⁻²⁷
= .6646 x 10²¹ m /s²
= 66.46 x 10¹⁹ m / s²
