determine the velocity and kinetic energy of neutrons having de broglie wave length 1 angstrom

at what temperature will the root mean square velocity of sulphur dioxide be same as that of methane at 27c?

on the ground a man A is movingwith velocity [3icap -4jcap]m/s and anotherman B is moving with velocity [icap+jcap]m/s relative to A. Find the relative velocity of B with respect to the ground.

If pressure is given by P=A+B by t and -c by D +v where t and v are time and velocity respectively then find dimensional formula of A, B,C&D.

Percentage error in displacement time and mass are 2%, 1% and 3%. Find percentage error in the measurement of force.

yes i mean the above equation which u have written P=A+B/T-C/D+V. The expression which shows how and which of the base quantities represent the dimensions of a physical quantity is called the dimensional formula.

plz sir help me

thank u mam.

i have not understood how n/m square it comes kgm/s2m2 and the cap symbol.
