when we say a weight of 50 kg is kept on a table, then is it 50 kg ? and force applied vertically down is 50x9.81 kgf?In earlier days this Newton unit was not there , it is confusing.pl help.
I want to know the fundamentals of finding the force reqd for moving a stationary object such as a car or a segway (which has got two wheels).
Also let me know in a formula mu = F/ NORMAL REACTION,
WHAT IS THE VALUE OF A WEIGHT HAS TO BE TAKEN?
meaning if weight of a person standing on a...
yes there is a diagram it shows,
a circle with radius r, centre O,
says mass M, THE ARROW TOUCHING THE CIRCLE PERIPHERY TANGENTIALLY . WITH VELOCITY v AND MASS m
I thought the text was quite sufficient.
Now nothing more to share
Dear Guruji
the problem as appearing in the textbook is as follows
"A bullet of mass m collides inelastically at the periphery of a disc of mass M and RADIUS r, with a speed v.The disc rotates about a fixed horizontal axis.Find theangular velocity of the disc bullet system just after the...
current is the charge passing through a cross section of a conductor per unit time
and drift velocity is the distance traveled by the electron in unit time
Thank you Sir.
Actually the power is required from the whole circuit and not from the unknown resistsnce.
Will you please help to get the answer for value of unknown resistance for getting max power?
SGT Sir,
Can you please calculate and show how to find out value of R by derivative method?
Hammie Sir,
This seems to be a different approach.What is impedence?Please explain your method to find value of "resistance.
This was a multiple choice question.to select one option out of four
1.electric field current and drift velocity will be same
2.Only current will be same
3.Only drift velocity will be same
4.None of the above
