CTSE results will be out very soon !!!
Physics has many definitions. In simple words Physics is branch of science concerned with the nature and properties of matter and energy
You just finished Kinematics
in a stretched string the speed of wave is 20m/s ` frequency 50hz . the find the phase difference in vibration of two point at string situate 10cm
Time (T), velocity (C) and angular momentum (h) are chosen as fundamental quantities instead of mass, length and time. In terms of these, the dimensions of mass would be :
What is a cell?
What is the difference between pleiotropy and polygenic inheritance
Molarity based on vol. Of solvent in 100litre of solu. While normality is gram molecular mass
Capacitance in a medium
A man of mass () is sitting in a train movingwith velocity . He observe that a block of mass is moving towards him with velocity . Then the kinetic energy of block w.r.t man is (Assume )
A block of mass m is kept on a platform which starts from rest with constant acceleration g/2 upward, as shown in the figure. Work done by normal reaction on block in time t is:
When the rms voltages VL, VC and VR are measured respectively across the inductor L, the capacitor C and the resistor R in a series LCR circuit connected to an AC source, it is found that the ratio VL : VC : VR = 1 : 2 : 3. If the rms voltage of the AC source is 100 V, then VR is close to ?
Substitute the value of C and V in the first equation
When both arms are parallel.
Write these in ascending and also in descending order.
