Nagin Bomb? Experiment @MR. INDIAN HACKER @Crazy XYZ #theexking #shorts #experiment #viral

A viral preparation was inactivated in a chemical bath. The inactivated in a chemical bath. The inactivation process was found to the first order in virus concentration and at the beginning of the experiment 2.0% of the virus was found to be inactivated per minute The k for the inactivated per minute The k for the inactivated process is (assume that there is no change in rate in the interval)

While doing an experiment on bomb calorimeter, a student made the following statement : DeltaH = DeltaU + pDeltaV Since in the experiment DeltaV =0 hence DeltaH = DeltaU .Is the student right or wrong? Justify.

In the Coolidage tube experiment, if the applied voltage is increased to three times, the short wavelength limit of continuous X- ray spectrum shift by 20 pm. What is the intial voltage (in kV) applied to the tube?

A short circuited coil is moved towards a fixed magnet at a constant velocity. When the coil is at a distance x from the magnet it experiences a magnetic force F. Now the number of turns in the coil is doubled and the experiment is repeated with the coil moving with same constant velocity towards the magnet. What will be the magnetic force on the coil when it is at a distance x from the magnet?
