It is impossible to determine the exact position and momentum of electron simultaneously. Therefore, option B is the correct answer.
According to Heisenberg’s uncertainty principle,it is impossible to determine simultaneously, the exact position and momentum of an electron.
Mathematical expression
ΔX.ΔP ≥ h/4π
ΔX = uncertainty in position
ΔP = uncertainty in momentum
h = Plank’s constant
π= Pi
Thus, we can conclude its nearly impossible to determine electron’s exact position. Therefore, option B is the correct answer.

Answer:
Explanation:
To determine the magnitude of the restraining force acting on the roller coaster cars, we can use the equation:
Force = Mass * Acceleration
1. Calculate the initial velocity:
Initial velocity (u) = 17.1 m/s
2. Calculate the final velocity:
Final velocity (v) = 2.2 m/s
3. Calculate the change in velocity:
Change in velocity (Δv) = v - u = 2.2 m/s - 17.1 m/s = -14.9 m/s (negative because the roller coaster is decelerating)
4. Calculate the distance traveled:
Distance (d) = 13.6 m
5. Calculate the acceleration:
Acceleration (a) = Δv / t
We need to calculate the time (t) first. To do this, we can use the equation of motion:
v = u + at
Rearranging the equation, we have:
t = (v - u) / a
Substituting the values, we have:
t = (-14.9 m/s) / a
6. Now, substitute the values into the equation to calculate the acceleration:
a = (v - u) / t
a = (-14.9 m/s) / (-14.9 m/s / a)
a = 1 m/s^2
7. Calculate the magnitude of the restraining force:
Force = Mass * Acceleration
Mass = 4768 kg
Force = 4768 kg * 1 m/s^2
Force = 4768 N
Therefore, the magnitude of the restraining force that acts upon the roller coaster cars is 4768 Newtons.
Answer:
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
Explanation:
B. A 250-N force moves an object 1 m.
C. A 25-N force moves an object 8 m.
D. A 600-N force is applied to an object and moves it 0 m.
b. more slowly than S waves.
c. at the same speed as S waves.
d. faster than S waves.
A seismogram shows that P waves travel faster than S waves. The answer is letter D. This is because P waves can push and pull the sound waves through a liquid or solid medium. The S wave can only move to the solid medium and solids have more compact molecules than the liquid so it travels slow.

Explanation:
Because P waves are the fastest seismic waves, they will ordinarily be the original 1 that your seismograph records. The following set of seismic waves on your seismogram will be the S waves. These are normally higher than the P waves. Often they are the only waves filmed a long distance from medium-sized earthquakes.
b. velocity.
c. frequency.
d. amplitude.
