derive the kinematics equation v=u+at by calculus method​

Answers 1

Explanation:

a= change of velocity/time taken

a = dv/dt

adt= dv

now integrating both side with limits 0 to t and u to v

then we get v =u+at

Answer:

  • Let us first understand the term Pythagorean triplet and then we will use a formula to determine all the numbers in a Pythagorean triplet of the given options one by one. First, we will divide the given number by two, then we will use n2−1

and n2+1

to determine the other two numbers.

A teflon rod was rubbed with a cloth having net charge -3. What will be the net charge on the teflon rod if it gains 3 electrons from the cloth. ​

Answer:

is also said that glass rod attracts the small uncharged paper pieces when it is becomes positively charged. I understand that a positively charged glass rod attracts the uncharged pieces of paper because some of the electrons present in the paper accumulate at the end near the rod, but can't we extend the same argument on attraction of negatively charged silk rod and the pieces of paper due to accumulation of positive charge near the end?

electrostatics

electricity

Answer:

The net charge would still be -3.

Explanation:

Because, when they are rubbed together, the teflon rod gains the electrons from the cloth. Which means that the cloth will lose its electrons. Thus, the combined net charge of both the objects will remain the same. This is the Law of Conservation of charge.

A train travels 360 km at a uniform speed. If, the speed had been 5 km/hr more, it would have taken 1 hour less for the same journey. Find the speed of the train​

Answer:

Given distance=360 km.

Let the speed of the train be x km/hr.

Speed when increased by 5 km/hr =(x+5) km/hr

x

360

−

(x+5)

360

=1

x(x+5)

[360x+1800−360x] =1

x

2

+5x−1800=0

x

2

+45x−40x−1800=0

x(x+45)−40(x+45)=0

(x−40)(x+45)=0

x=40,−45

The speed of the train is 40 km/hr.
