Why tio2 is used in DSSC? The titanium dioxide used in DSSC. TiO2 semiconductor is the widely used electron conductor in Gråtzel-type photovoltaic DSSC, because of its low-cost and ease of synthesis. Which is used in solar cell material? Silicon What is the principle of photovoltaic cell? Photovoltaics are best known as a method for […]
What is the source of electricity in batteries?
What is the source of electricity in batteries? All batteries convert stored chemical energy into electrical energy. This is achieved through causing electrons to flow whenever there is an external conductive path between the cell’s electrodes. Is it OK to leave Battery Tender on all the time? In theory, you can leave the Battery Tender® […]
Which sedimentary cycle is only?
Which sedimentary cycle is only? The phosphorus cycle is also the sedimentary cycle. This phosphorus cycle is said to be a sedimentary cycle because of the sedimentary rocks and the other rocks which gives rise to the cycling of the phosphorus from the abiotic component to the biotic components to the back. Is phosphorus cycle […]
When two point charges of magnitude q1 and q2 are separated by a distance r the magnitude of the electrostatic force between them is F?
When two point charges of magnitude q1 and q2 are separated by a distance r the magnitude of the electrostatic force between them is F? Thus upon changing the charges and distance between the charges the magnitude of the new force will be two times the magnitude of earlier force, i.e. 2F. What is the […]

How cold does it have to be for RV pipes to freeze?
How cold does it have to be for RV pipes to freeze? In general, the temperature has to dip below freezing (32 F) for approximately 24 hours for RV pipes to freeze. This is all dependent on many factors such as if you have an enclosed underbelly, heated underbelly, heat tape, insulation, or other preventative […]
How many types of radiation are there?
How many types of radiation are there? two kinds Do humans need radiation? It comes from natural uranium and thorium (and their decay products) in the Earth’s crust, from a naturally radioactive form of potassium (which we all need to survive), from cosmic radiation, and many other sources. Humans and all life on the planet […]
Why would you not use laboratory thermometer for measuring your body temperature?
Why would you not use laboratory thermometer for measuring your body temperature? A laboratory thermometer cannot be used to measure the temperature of a human body because the range of a laboratory thermometer is high generally from –10°C to 110°C, while as normal body temperature in humans is only 37°C. What is the acceptable tolerance […]
