Answer:
circumference= 65/3 cm = 21.67 cm
radius R = 3.45 cm
Explanation:
To calculate the length of the circumference of the cylinder, we divide 650 cm by 30 (the number of times it wrapped exactly around it)
length of circumference= 65/3 cm = 21.67 cm
now use the formula of the circumference length to find the radius (R):
circumference length = 2 * pi * R
65/3 = 2 * pi * R
R = 65 / (6 pi)
R = 3.45 cm
Answer:
It would be hard to make a model that shows the real sizes and distances between planets ( B )
Explanation:
Yuri building a model of the solar system will face the difficult of replicating the correct distances between the planets and the real sizes of the planets, because in model building the key factors of the Model must be represented properly.
The size of the planets and the distance between the planets are key factors when trying to model the solar system. but the distance between the planets depends on the position of the planets on their orbits which means the distances are not constant ( fixed ) hence that would be the limitation of his model.
Answer:
the energy of the spring at the start is 400 J.
Explanation:
Given;
mass of the box, m = 8.0 kg
final speed of the box, v = 10 m/s
Apply the principle of conservation of energy to determine the energy of the spring at the start;
Final Kinetic energy of the box = initial elastic potential energy of the spring
K.E = Ux
¹/₂mv² = Ux
¹/₂ x 8 x 10² = Ux
400 J = Ux
Therefore, the energy of the spring at the start is 400 J.
