What removes gunpowder from hands? As time passes after discharge, GSR particles can be removed from the hands by contact with other objects or by hand washing. What two tests are performed to detect GSR on clothing? Chemical test enhancement on GSR involves the use of Modified Griess test and Lunges reagent test to detect […]
What three things to elements in the same group have in common?
What three things to elements in the same group have in common? Elements in the same group are those that are in a single vertical line from top to bottom. They have the most in common between the two directions. They share the same number of electrons in their valence subshells. As a result, they […]
How can I keep warm in the winter without electricity?
How can I keep warm in the winter without electricity? The best ways to stay warm during a power outage are to wear layers, stay in a confined space, use blankets and battery-powered space heaters, and to avoid exposing your home to cold air. Do not use camp stoves, car engines, gas stoves and ovens, […]
What are the 7 main neurotransmitters?
What are the 7 main neurotransmitters? Fortunately, the seven “small molecule” neurotransmitters (acetylcholine, dopamine, gamma-aminobutyric acid (GABA), glutamate, histamine, norepinephrine, and serotonin) do the majority of the work. What diseases affect neurotransmitters? When neurotransmitters are affected by disease or drugs, there can be a number of different adverse effects on the body. Diseases such as […]
What would happen if this moon slowed down?
What would happen if this moon slowed down? The moon slows down the Earth’s rotation, but a moon explosion would disrupt the friction. This means that every day would be 24 hours long for the rest of the Earth’s existence. The Earth’s tides would also change because the gravity the moon exerts on the oceans […]
What are the 4 factors that affect population growth?
What are the 4 factors that affect population growth? Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration. What are three ways ecologists can estimate the size of a population? Two important measures of a population are population size, the number of individuals, and population density, the number of […]
What are the pros to GMOs?
What are the pros to GMOs? The possible benefits of genetic engineering include: More nutritious food. Tastier food. Disease- and drought-resistant plants that require fewer environmental resources (such as water and fertilizer) Less use of pesticides. Increased supply of food with reduced cost and longer shelf life. Faster growing plants and animals. Is broccoli a […]
How does an angle affect tension?
How does an angle affect tension? A change in the angle will affect the amount of horizontal pull in the cable which in turn affects the amount of tension in the cable. The more horizontally aligned the cable is, the more it will pull horizontally. This increased horizontal pull will increase the tension in the […]
How does RC circuit work?
How does RC circuit work? RC Circuits. An RC circuit is a circuit with both a resistor (R) and a capacitor (C). A capacitor can store energy and a resistor placed in series with it will control the rate at which it charges or discharges. This produces a characteristic time dependence that turns out to […]
What is the probability of an electron being found?
What is the probability of an electron being found? An orbital is, more correctly, a mathematical function, 4pr2Y2, that describes the region of high probability in 3D space, around a nucleus, where an electron may be found. Orbitals are commonly represented by the boundary surfaces that encloses the region where there is a 90-95 % […]
