The definition of a scale of 1: 166 will mean that the scale of 1 in the model will be equivalent to 166 times the measurement in the real model, therefore we will have that the height would be 166 times smaller than the 179m given:
The same for the diameter,
The volume of a cylinder is given as
Therefore the volume would be
Answer:
Gravitational force mg' =(49)mg=49×63=28N.
Explanation:
What is the gravitational force on it due to the Earth , at a height equal to half the radius of the Earth ? (Given that the radius of Earth = 6400 km). Gravitational force mg ( This is not the real explanation)
The thing that pushes the object up while it is falling is air. This force is known as "air resistance".
Answer: pick A moves 10.2 metre
Explanation: since they were given a quick push simultaneously the product of their distance moved and velocity would be equal.
Let the distance moved by puck B x then that of puck A would be 18-x.
So therefore we have that,
1.3*(18-x) = 1.7*x
23.4 - 1.3x = 1.7x
23.4=3x
Making x subject of formula we have
x = 23.4/3 = 7.8m
But the distance moved by puck A is 18-x. So therefore,
18-7.8=10.2meter
