Hello I need help with these questions

46 Which of these statements about nuclear energy is false? Points: 1 A Today, nuclear power plants account for 11 percent of global electricity generation with about 80 percent of that installed capacity being in OECD countries. B Nuclear fusion is the same process that powers our Sun. Fusion is a nuclear reaction in which atomic nuclei collide at a high speed and join to form a new type of atomic nucleus. During this process, matter is not conserved because some of the matter of the fusing nuclei is converted to photons which produces energy. C Nuclear energy through fission can release 1 million times more energy per atom than fossil fuels. Nuclear plants have large power generating capacity but a high operating cost, making it challenging for base load generation. D Fission produces energy through the splitting of atoms which releases heat energy that can be harnessed to produce electricity. The fuel most commonly used for nuclear fission is uranium. However other elements such as plutonium and thorium can also be used. All of today's operating nuclear plants use nuclear fission to generate electricity. (E Nuclear energy is the energy held in the nucleus of an atom. It can be obtained by two types of reactions, fission and fusion. F Fusion power offers the prospect of an almost inexhaustible source of Energy. However, creating the conditions for nuclear fusion presents a potentially insurmountable scientific and engineering challenge. 47 Which of these statements about oil drilling is false? Points: 1 A Once a candidate drilling site is determined, the drillers make a hole of small diameter from 20 to 50 centimeters. This hole will generally go down to a depth of between two thousand and four thousand meters. Generally, the best position for the installation of the drilling equipment is vertically above the point of maximum thickness of the geological layer suspected of containing hydrocarbons. C The derrick is the visible part of the drilling used to vertically introduce the drill strings down the hole. D Exceptionally, certain wells exceed six thousand meters. One of them has even exceeded fifteen thousand meters. 48 Which of these statements about tidal power energy is false? Polls: 1 A) Tidal electricity can be created from several technologies, the main ones being tidal barrages, tidal fences, and tidal turbines. Tidal barrages are the most efficient tidal energy sources. B Tidal power tidal power is a form of hydropower that converts the energy from the natural rise and fall of the tides into electricity. C Tidal plants can only be installed along coastlines. Coastlines often experience two high tides and two low tides on a daily basis. The difference in water levels must be at least ten meters high to produce electricity. D A tidal barrage is a dam that utilizes the potential energy generated by the change in height between high and low tides. This energy turns a turbine or compresses air which in turn creates electricity. E Tides are caused by the combined effects of gravitational forces exerted by the moon the Sun and the rotation of the earth
