Where do we use chemical energy?
Where do we use chemical energy? Chemical batteries: Store chemical energy to be changed into electricity. Biomass: Combustion reaction converts chemical energy into light and heat. Natural gas: Combustion reaction converts chemical energy into light and heat. Food: Digested to convert chemical energy into other forms of energy used by cells. How does the body […]
Can we see polarized light?
Can we see polarized light? Though most of us are unaware of our capacity to do so, humans can also perceive the polarization of light. We detect the orientation of polarized light using ‘Haidinger’s brushes’, an entoptic visual phenomenon described by Wilhelm Karl von Haidinger in 1844 [2]. How can you tell if light is […]
How can charging current be reduced?
How can charging current be reduced? As the battery voltage nears fully charged, current will decrease. If you adjust potentiometer R2 so that the output voltage is 13.6v-13.7v at room temp (25°C/77°F), you can leave the charger on the battery indefinitely. Is 3.1 amp a fast charger? A USB device generally uses very little amps […]
What is a secondary source in writing?

How do you find the direction of force in an electric field?
How do you find the direction of force in an electric field? Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge […]
What is the difference between red vs yellow marrow?
What is the difference between red vs yellow marrow? Red blood cells, platelets and most white blood cells arise in red marrow; some white blood cells develop in yellow marrow. The color of yellow marrow is due to the much higher number of fat cells. Both types of bone marrow contain numerous blood vessels and […]
