The surface of the table and brick may not match up perfectly. This means that friction may occur leading to the brick slowing down or some bit of heat resulting from the contact.
Answer:
b)7.89 g
c) 7.91 g
d) 7.97 g
Explanation:
The accepted value for the measurement is 7.92 g, while the precision of the instrument is 0.05 g. Therefore, the interval of the accepted values will be the central value plus and minus the precision, so:
- Minimum accepted value: 7.92 g - 0.05 g = 7.87 g
- Maximum accepted value: 7.92 g + 0.05 g = 7.97 g
So, the accepted interval is
7.87 g - 7.97 g
Therefore, all the values that lie within this interval are accepted. So the accepted values are:
b)7.89 g
c) 7.91 g
d) 7.97 g
Distance D = 5 cm = 0.05m
Revolutions = 33.33 per min => t = 60 sec
Acceleration is v^2 / r, so first we need to find velocity
Velocity = (D x 3.14 x r) / t => (0.05 x 3.14 x 33.33) / 60
Velocity = 0.0872 m/s
Acceleration = v^2 / r = 0.0872^2 / 0.05 = 0.152.
Answer:
Explanation:
The probability of fi in a range is given by the integral, whose limits are the range limits, of the square of the wave function y(x).
Example:
let's say range [a,b] with wave function y(x), then
