for this we apply, Heisenberg's uncertainty principle.
it states that physical variables like position and momentum, can never simultaneously know both variables at the same moment.
the formula is,
Δp * Δx = h/4π
m(e).Δv * Δx = h/4π
by rearranging,
Δx = h / 4π * m(e).Δv
Δx = (6.63*10^-34) / 4 * 3.142 * 9.11*10^-31 * 5.10*10^-2
Δx = 6.63*10^-34 / 583.9 X 10 ⁻³¹
Δx = 0.011 X 10⁻³
for the bullet
Δx = (6.63*10^-34) / 4 * 3.142 * 0.032*10^-31 * 5.10*10^-2
Δx = 6.63*10^-34 /2.05
Δx =3.23 X 10⁻³² m
therefore, we can say that the lower limits are 0.011 X 10⁻³ m for the electron and 3.23 X 10⁻³² m for the bullet

Answer:
It depends on the size and density but No.
Explanation:
To solve this problem you must apply the proccedure shown below:
1. You must apply the formula for calculate the mechanical advantage, which is:
M.A=Wheel radius/Axle radius
2. Therefore, you have:
Axle radius=0.25 inches=0.0208 feet
Wheel radius=1 feet
M.A=1 feet/0.0208 feet
M.A=48
Therefore, the answer is: 48
Answer:
solids are strong and compact, they are not compressable.
liquids are flexible and less compacts they can not be coompresed
Answer:
Bouyant Force is 19.6N and the object will sink
Explanation:
The buoyant force is equal to the weight of displaced water(Archimedes Principle). Since 2.00 kg of water were displaced, the buoyant force would be equal to:
Fb = Fw = mg = (2.00 kg)(9.81 m/s²) = 19.6 N
Where Fb is buoyant force
Where Fw is weight of displaced water
The object will float if the buoyant force is greater than its weight, and sink if the reverse is true. Since the object's mass is 3.00 kg, its weight is:
Fw = mg = (3.00 kg)(9.81 m/s²) = 29.4 N
Since the object's weight, 29.4 N, is greater than the weight of displaced water, the object will sink.
