Answer:

Definition. Nuclear physics is the study of the protons and neutrons at the centre of an atom and the interactions that hold them together in a space just a few femtometres (10-15 metres) across. Example nuclear reactions include radioactive decay, fission, the break-up of a nucleus, and fusion, the merging of nuclei.

The uncertainty in position of a proton confined to the nucleus of an atom is roughly the diameter of the nucleus. If this diame
irakobra [83]

<u>Answer:</u> The uncertainty in proton's momentum is 1.3\times 10^{-20}kg.m/s

<u>Explanation:</u>

The equation representing Heisenberg's uncertainty principle follows:

\Delta x.\Delta p\geq \frac{h}{2\pi}

where,

\Delta x = uncertainty in position = d = 7.8\times 10^{-15}m

\Delta p = uncertainty in momentum = ?

h = Planck's constant = 6.627\times 10^{-34}kgm^2/s^2

Putting values in above equation, we get:

\Delta p=\frac{6.627\times 10^{-34}kgm^2/s^2}{2\times 3.14\times 7.8\times 10^{-15}m}\\\\\Delta p=1.3\times 10^{-20}kg.m/s

Hence, the uncertainty in proton's momentum is 1.3\times 10^{-20}kg.m/s

Suppose that while moving into an apartment you move a refrigerator into place by sliding it across the floor. The refrigerator w
sweet-ann [11.9K]

Answer:

358 N

Explanation:

F=\mu N where F is the force, \mu is the coefficient of static friction between the floor and the refrigerator and N is the weight

Normally, N=mg hence F=\mu mg where m is the mass of object and g is the acceleration due to gravity

In this case, N is given as 895 N and the coefficient of static friction between the floor and the refrigerator is 0.400 hence substituting them in the formula we obtain

F=\mu N= 0.4\times 895 N= 358 N

How objects on Earth are affected by gravitational force.
stellarik [79]

Answer:

The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases. Both objects exert an equal attractive force on each other: a falling object is attracting the Earth with the same size force as the Earth is attracting it

How do we know what is inside of Earth ?
Maslowich

Answer:

Most of what we know about the interior of the Earth comes from the study of seismic waves from earthquakes. Seismic waves from large earthquakes pass throughout the Earth. These waves contain vital information about the internal structure of the Earth.
