Use the equation I=V/R where I is current and V is the voltage plus R is the resistance so when voltage is the highest and resistance is lowest the current is the highest
When anyone pass the puppy then it will block the visible light that incident upon it
So here we are blocking the visible part of light by passing the puppy which means we have to design a sensor that will sense the visible light.
So here the electromagnetic part of the sensor is capable to detect this change only
so here correct answer must be
<u><em>B. Visible Light</em></u>
Pressure= F/A
Given, F=30 N
Area=20 m^2
Putting values in formula,
Pressure = 30/20
=3/2
=1.5 Pascals
Answer:
Isotopes
Answer:
The number of neutrons can vary, but not protons. This is called an isotope. An example is deuterium, an isotope of hydrogen with an extra neutron, but the same number of protons.
