Answer:
For the non covalent bonding interaction the following statement is incorrect.
" Charge induced dipole interactions are inversely proportional to the sqaure of the distance between the two atoms"
because charge induced dipole interactions are directly proportional to the square of the distance between the two atoms.
Explanation:
Buckle and adjust their seatbelts
Which describes the combination of two primary colors of light to produce a secondary color of light?
a. Yellow light and blue light combine to produce green light.
b. Magenta light and cyan light combine to produce blue light.
c. Red light and green light combine to produce yellow light.
d. Green light and yellow light combine to produce white light.
Answer:
b. Magenta light and cyan light combine to produce blue light.
Explanation:
Primary colour is any of three colours which, when added to or subtracted from others in different amounts, can generate all other colours.
• Red, blue and green are additive primary colours..
• Magenta, yellow and cyan are subtractive primary colours.
As per the problem, the charge is of 2.5μC, moving in magnetic field
T and having velocity
m/s, the force comes out to be 3.75N
<h3>
what is magnetic force?</h3>
Magnetic force is the force experienced by the object inside the magnetic field or flowing current across the conductor. This force is caused due to the movement of charges.
The force exerted is magnetic force which is given as,
![F= QVBsin\theta](https://tex.z-dn.net/?f=F%3D%20QVBsin%5Ctheta)
here,
Q= charge
v= velocity
B= Magnetic field and
=Angle of object from magnetic field
![F=2.5\times10^{-6} \times 5\times10^{3} \times3\times10^{2}\times sin90](https://tex.z-dn.net/?f=F%3D2.5%5Ctimes10%5E%7B-6%7D%20%5Ctimes%205%5Ctimes10%5E%7B3%7D%20%5Ctimes3%5Ctimes10%5E%7B2%7D%5Ctimes%20sin90)
![F=3.75N](https://tex.z-dn.net/?f=F%3D3.75N)

Answer:
1.54 s
Explanation:
Considering that the legs constitute 16% of the total weight of the man then mass, ![m= \frac {16}{100}\times 67=10.72 Kg](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%20%7B16%7D%7B100%7D%5Ctimes%2067%3D10.72%20Kg)
The legs also constitute 48% of his height hence ![H=\frac {48}{100}\times 1.83=0.8784 m](https://tex.z-dn.net/?f=H%3D%5Cfrac%20%7B48%7D%7B100%7D%5Ctimes%201.83%3D0.8784%20m)
The moment of inertia of a cylinder rotating about a perpendicular axis at one end is
hence ![I=\frac {10.72\times 0.8784^{2}}{3}=2.757135974Kg.m^{2}](https://tex.z-dn.net/?f=I%3D%5Cfrac%20%7B10.72%5Ctimes%200.8784%5E%7B2%7D%7D%7B3%7D%3D2.757135974Kg.m%5E%7B2%7D)
We also know that the period is given by ![2\pi \sqrt{\frac {I}{mgh}}](https://tex.z-dn.net/?f=2%5Cpi%20%5Csqrt%7B%5Cfrac%20%7BI%7D%7Bmgh%7D%7D)
Here, h=0.5H= 0.5*0.8784=0.4392 m
Taking g as 9.81 kg/m2 then
![T= 2\pi \sqrt{\frac {2.757135974}{10.72\times 9.81\times 0.4392}}\\=1.535132615 s\\\boxed{\approx 1.54 s}](https://tex.z-dn.net/?f=T%3D%202%5Cpi%20%5Csqrt%7B%5Cfrac%20%7B2.757135974%7D%7B10.72%5Ctimes%209.81%5Ctimes%200.4392%7D%7D%5C%5C%3D1.535132615%20s%5C%5C%5Cboxed%7B%5Capprox%201.54%20s%7D)
