Answer:
- The accuracy in measuring its velocity decreases.
Explanation:
This can be explained by Heisenberg's uncertainty principle which states that the position and velocity of a particle can be determined together exactly in reality.
This principle, unlike Newtonian mechanics deal with particles at microscopic level like that of an electron where if the accuracy in measurement of particle's position increases there will be decreased accuracy in measurement of velocity of that particle.
There will be an uncertainty in accuracy in the measurement of particle's position and its velocity.
185 newtons because (W=Fd so W/d=F)296/1.6=185
Answer:
0.29713 m/s
Explanation:
m = Mass of person
g = Acceleration due to gravity = 9.81 m/s²
v = Velocity
r = Radius = 18 mm
By balancing the forces in the system we have

The velocity of the coaster is 0.29713 m/s
Let
be the height of the building and thus the initial height of the ball. The ball's altitude at time
is given by

where
is the acceleration due to gravity.
The ball reaches the ground when
after
. Solve for
:


so the building is about 16 m tall (keeping track of significant digits).
Answer:
1.8m
Explanation:
Let the Elastics of the steel ASTM-36 
The strain of the bar when subjected to 150 MPa is

Therefore, if the bar elongates by 1.35 mm, then the original length L would be:

or 1.8m
