A 50.0-g toy car travelling with a velocity of 3.00 m/s due north collides head-on with a 180.0-g fire truck travelling with a velocity of 0.50 m/s due south.
The toys stick together after the collision.
What are the magnitude and direction of their velocity after the collision?
What is the principle of generating ultrasonic waves? The general principle comprised in generating ultrasonic waves is to reasons some dense material to vibrate very quickly.
The mass of a proton and of an antiproton is 1.00728 u. Recall that the conversion of exactly 1 u into energy yields 931.5 MeV. a. Measure the mass used up when a proton and
why The magnitude of known potential difference must be greater than the value of unknown potential difference to be measured.
With the help of a diagram, show the biasing of a light emitting diode (LED). Give its two benefits over conventional incandescent lamps.
