Answer:
electron dot diagram is the answer to your question.
Answer: Option (A) is the correct answer.
Explanation:
Models of solar system has been designed from time to time. The present model of solar system shows that nine planets are orbiting around the Sun.
This model is also known as Heliocentric model whereas it is also shown that only Pluto has different orbit as compared to rest of the planets.
Therefore, we can conclude that the model of the solar system changed, because understanding of the solar system changed.
Answer:
N1 / N2 = 1.0016
Explanation:
The apparent weight of the student is the value that a balance would have this corresponds in this case to the normal of the student. Let's write Newton's second law in the lower and upper part of the loop
For lower rotating wheel
N1 - W = m a
a = v² / r
N1 = W + v² / r
The relationship between linear and angular velocity is
v = w r
As the wheel rotates at a constant speed, we can use angular kinematics
w = θ / t
θ = 3 rev (2π rad / 1rev) = 6π rad
w = 6π / 150
w = 0.04π rad / s = 0.1257 rad / sec
calculate
N1 = mg + w² r
N1 = 55 9.8 + 0.1257² 27
N1 = 539 + 0.4267
N1 = 539.426 N
Now we perform the same calculation for the top
-N2 - W = -m a
N2 = -W + ma
N2 = 539 - 0.4267
N2 = 538.5733 N
The relationship between the weight at the bottom and top is
N1 / N2 = 539.4267 / 538.5733
N1 / N2 = 1.0016
BAH! Took me forever to think of it.
The Scientific method.
Brainliest please. :D
