What are the types of LDR? Light dependent resistors, LDRs or photoresistors fall into one of two types or categories: Intrinsic photoresistors: Intrinsic photoresistors use un-doped semiconductor materials including silicon or germanium. What is the purpose of LDR? An LDR is a component that has a (variable) resistance that changes with the light intensity that […]
Do roller coasters just use gravity?
Do roller coasters just use gravity? A roller coaster is a machine that uses gravity and inertia to send a train of cars along a winding track. The combination of gravity and inertia, along with g-forces and centripetal acceleration give the body certain sensations as the coaster moves up, down, and around the track. How […]
Who signs contract first buyer or seller?
Who signs contract first buyer or seller? Once a real estate seller and buyer agree to terms, the seller normally signs a real estate purchase agreement or sales contract. Real estate buyers are generally expected to sign purchase agreements first, though, especially during offer and counteroffer phases. What is a deed consideration? Consideration is a […]
Why was England most successful in colonizing America?
Why was England most successful in colonizing America? The English that settled the middle colonies of New York and Pennsylvania found good farmland that was great for growing food that could be sold in Europe. Finally, the English that colonized the southern colonies found that area was good for growing cash crops like tobacco. What […]
How fast do planes fly in mph?
How fast do planes fly in mph? The typical cruising airspeed for a long-distance commercial passenger aircraft is approximately 880–926 km/h (475–500 kn; 547–575 mph). Was the mosquito faster than the Spitfire? During its trials on 16 January 1941, W4050 outpaced a Spitfire at 6,000 ft (1,800 m). The original estimates were that as the […]

What is the best wattage microwave to buy?
What is the best wattage microwave to buy? A 1,000-watt or 1,200-watt option is the best for most people’s needs, however. It’s enough power to heat or defrost anything from the freezer section thoroughly. Cheaper microwaves with under 700-watts take longer to cook your food efficiently and may struggle to heat things evenly. How do […]
Which gases is not a greenhouse gas?
Which gases is not a greenhouse gas? Examples for greenhouse gases: Carbon dioxides, Methane, Chlorofluorocarbon, sulphur dioxide. Whereas oxygen, nitrogen and argon are not examples of greenhouse gases. Is nitrogen monoxide a greenhouse gas? The direct greenhouse gases are carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4). The indirect greenhouse gases are non-methane volatile […]
Why is a car crash inelastic?
Why is a car crash inelastic? Collisions are considered inelastic when kinetic energy is not conserved, but this could be from either a loss or gain or kinetic energy. For example, in an explosion-type collision, the kinetic energy increases. It is common for people to try to conserve energy in a collision. What happens in […]
When a slab of dielectric medium is placed between plates of a parallel plate capacitor which is connected with a battery then the charge on plates in comparison with earlier charge?
When a slab of dielectric medium is placed between plates of a parallel plate capacitor which is connected with a battery then the charge on plates in comparison with earlier charge? Two identical capacitors are connected as shown in the figure. A dielectric slab is introduced between the plates of one of the capacitors so […]
