If magnification is less than one it means the image is the same exact size as the object.
Answer:
3. both are true.
Explanation:
Energy increses with decrease in wavelenght.
For photoemission to occur, a threshold energy barrier must be broken.
Higher energy means more electrons will be emmited.
The electrons emmited will posses energy that is less than the incident energy by the value of the threshold energy.
So the higher the energy, the higher the energy possessed by the electrons.
pH is the measure of the concentration of hydrogen ions in a solution
Explanation:
the object has constant velocity for 2 seconds and it get a constant accelration (2ms-2)
