Applications of magnetic and electrostatic force.

Answer»

Electrostatics is a branch of physics that STUDIES electric charges at rest. Since classical physics, it has been known that some materials such as amber attract lightweight particles after rubbing

Applications of MAGNETIC forces and fields. There are a number of good applications of the principle that a magnetic field exerts a force on a MOVING charge. One of these is the mass spectrometer : a mass spectrometer separates CHARGED particles (USUALLY ions) based on their mass

42.

Which has more molecule a kilogram of hydrogen or a kilogram of oxygen?

Answer»

Hello friend your answer!!
a kilogram of hydrogen is having more molecules.
For hydrogen that value is 1.008. For OXYGEN it’s 16.00. That means HOWEVER MANY times you can divide the mass by its molar mass, So for example 1000G (1kg) / 1.008 is approxametly 992 moles of hydrogen. And 1000g/16.00 is 62.5 moles of Oxygen. Now to put it all together, one mole is equal to 6.02x10^23 molecules so obviously since there are more moles of hydrogen, you would have a significantly larger amount of hydrogen.

Check the correctness by using dimensional formula ofF=mv^2/ r here 'm" denotes mass of the body,"v"stands for velocity & "r" represents radius of earth.#No spam answers.Answer if u can ✌from chapter "Dimensional Analysis" physics 11th CBSE

Answer»

Hey.
here is your answer

We KNOW that,

velocity (v) = LT-¹
and
radius (r) = L ,
MASS (m)= m

on putting the value in the above equation
F= M×(LT-¹)²/ L
F= ML²T-²/ L
F=M¹L¹T-²

hence your relation is correct

Difference between cosmological redshift and doppler shift

Answer»

.. Practically speaking, the difference between the TWO (Doppler REDSHIFT and cosmological redshift) is this: in the case of a Doppler shift, the only THING that matters is the relative velocity of the EMITTING object when the light is emitted compared to that of the receiving object when the light is received.

A girl joos from one end A to other end B of a straight 250m road in 1min40sec. She then turn around and 50 m back to point C in 30sec. Find average speed and average velocity in jogging from A to C

Answer» TOTAL DISTANCE covered by girl(s) =250m+50m
=300m
total time TAKEN(t) =1min40sec+30sec
=130sec
average speed=s/t
=300/130
=2.307m/s
NOW,
DISPLACEMENT of girl=250m-50m
=200m
total time taken=130sec
average velocity=total displacement/total time taken
=200/130
1.53m/s
