Answer: Option (d) is the correct answer.
Explanation:
Dalton's model of atom states that every matter is made up of atoms and these atoms are indivisible in nature.
On the other hand, Thomson's model of atom states that there are small particles present in an atom that has positive or negative charges.
Thomson's model of atom is also known as plum pudding model where negatively charged particles are represented by plum and positively charged particles are represented by pudding.
Thus, we can conclude that Thomson’s model of the atom include smaller particles that Dalton’s model did not have.
Answer:
D
Explanation:
The friction force is the weight force times the coefficient of friction. So diving by the coefficient gives you the weight force which is equivalent to the normal force.
Answer:
45.6m
Explanation:
The equation for the position y of an object in free fall is:
With the given values in the question the equation has one unknown v₀:
Solving for t=1:
1) 
To find the hight of the tower you can use the concept of energy conservation:
The energy of the body 1 sec before it hits the ground:
2) 
If h is the height of the tower, the energy on top of the tower:
3) 
Combining equation 2 and 3 and solving for h:
4) 
Combining equation 1 and 4:
