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.
Make sure the triple beam balance is at 0 before you begin.
Answer:
As 28m/s = 28m/s
Explanation:
r = the radius of the curve
m = the mass of the car
μ = the coefficient of kinetic friction
N = normal reaction
When rounding the curve, the centripetal acceleration is
therefore
As 28m/s = 28m/s
During a total solar eclipse, the moon passes between Earth and the sun. This completely blocks out the sun’s light. However, the moon is about 400 times smaller than the sun. How can it block all of that light?
Probably for the umbilical cord that connects babies (from their early stages in the womb to their removal) to their mothers. The cord is cut, forming the belly button. This is analogous to astronauts in space.
