Given that,
The radius of a flywheel, r = 20 cm = 0.2 m
The centripetal acceleration experienced on the edge of the flywheel = 900 cm/s² = 9 m/s²
To find,
The speed of a point on the edge.
Solution,
The formula for the centripetal acceleration is given by :
Hence, the required speed is 1.34 m/s
Answer:
Trial 1: 2 Volts, 0 %
Trial 2: 2.8 Volts, 0%
Trial 3: 4 Volts, 0 %
Explanation:
Th experimental values are given in the table, while the theoretical value can be found by using Ohm/s Law:
V = IR
<u>TRIAL 1</u>:
V = IR
V = (0.1 A)(20 Ω)
<u>V = 2 volts</u>
% Difference = x 100%
% Difference = |(2 - 2)/2| x 100%
<u>% Difference = 0 %</u>
<u>TRIAL 2</u>:
V = IR
V = (0.14 A)(20 Ω)
<u>V = 2.8 volts</u>
% Difference = x 100%
% Difference = |(2.8 - 2.8)/2.8| x 100%
<u>% Difference = 0 %</u>
<u></u>
<u>TRIAL 3</u>:
V = IR
V = (0.2 A)(20 Ω)
<u>V = 4 volts</u>
% Difference = x 100%
% Difference = |(4 - 4)/4| x 100%
<u>% Difference = 0 %</u>
The second statement is your answer:
No change in temperatures between seasons. Since tilt is the angle between the direction of positive pole and the normal to the orbital plane, seasons occur due to the tilt of axis. If there were to be no, or zero degree tilt, then there will be no season because of the lack in temperature changes. The amount of sunlight received remains same throughout the year which results in no temperature change
Answer:
By nature, laws of Physics are stated facts which have been deduced and derived based on empirical observations. Simply put, the world around us works in a certain way, and physical laws are a way of classifying that “working.”
