Which one of the following accurately describes the force of gravity? 1 Answer. The gravity acceleration is in the same direction as the force of gravity, and thus toward the center of the earth accurately describes the force of gravity. Which of the following does not accurately describe the universal gravitational law? Gravitational force is […]

Do arrows kill instantly? A person shot with an arrow is unlikely to die instantly, or even particularly quickly. An important part of hunting, even with a gun, is tracking the animal after it’s dead. Even deer, which are not as big or tough as humans, do not die as soon as the arrow passes […]

What controls the opening and closing of stomata? Two highly specialized cells, the guard cells that surround the stomatal pore, are able to integrate environmental and endogenous signals in order to control the stomatal aperture and thereby the gas exchange. Why plants do not need specialized respiratory system? Plants take in carbon dioxide and give […]

How much current can transistor handle? It’s usually around 100, but can range from 50 to 200…even 2000, depending on which transistor you’re using and how much current is running through it. If your transistor had a β of 100, for example, that’d mean an input current of 1mA into the base could produce 100mA […]

Is it bad to run a 2 stroke out of gas? Running a 2-stroke out of fuel is theoreticly bad. The bottom end will be fine because of the oil left over but it creates an extreme lean condition in the top end. Unlike a 4-stroke which usually dies as soon as it’s out of […]

Can fire power a solar panel? Solar panels pose an extremely low fire hazard. In fact, Photon magazine has recorded no more than 1 incident per 10, 000 installations. So a house equipped with properly installed solar panels will not catch fire. First off, it must be noted that photovoltaic solar panels cannot start a […]

Why does oil get hot? Water have low density and oil have high density , 2nd heat capacity of water is low and oil heat capacity is high so that why it get hoter than water. When you heat water up, it eventually boils; you can’t get it any hotter than that. How do you […]

Who is the youngest Nobel Prize winner in science? The youngest Nobel Laureates Age Name Category/Year 17 Malala Yousafzai Peace 2014 25 Lawrence Bragg Physics 1915 25 Nadia Murad Peace 2018 31 Werner Heisenberg Physics 1932 Which Nobel prize is given every year? The Nobel Peace Prize award ceremony usually takes place at the Oslo […]

Why do I feel weird after riding an elevator? According to physics, we will continue to remain in a state of rest as long as we are stationary, however when you throw the sudden movement of an elevator working against the force of gravity into the mix, this equilibrium is broken, resulting in a dizzy […]

What do solid and gas have in common? Solid, Liquids, and Gases. Sold, liquid, and gas all have volume and shape. They are all made up of atoms, molecules, or ions. Liquids and solids can be referred to as condensed phased because their particles are close together. Liquids and gases flow easily because their particles […]
