What happens to resistance if wire diameter is decreased? As we know that resistance of a wire is inversely proportional to the square of its diameter. Thus when the diameter of a wire is doubled (made 2 times), its resistance becomes one-fourth (1/4), and if the diameter of a wire is halved (made 1/2), then […]
How do you tell if a polarizer is circular or linear?
What is the weight of an object on moon if the weight of the same object on earth is 100 N?
What are 2 types of pollination?
What are 2 types of pollination? Pollination takes two forms: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. What color flowers are bees attracted to? The most likely colors to attract bees, according to scientists, are […]
How much is an FFA jacket?
What can be inferred about the relationship between current and resistance?
What can be inferred about the relationship between current and resistance? The relationship between voltage, current, and resistance is described by Ohm’s law. This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r. What is the […]
What is the purpose of a theory of change?
What is the purpose of a theory of change? Theory of Change (ToC) is a methodology for planning, participation, and evaluation that is used in companies, philanthropy, not-for-profit and government sectors to promote social change. Theory of Change defines long-term goals and then maps backward to identify necessary preconditions. How do you write an effective […]
How does the muscular system work with the digestive system?
How does the muscular system work with the digestive system? The muscular system allows for movement within the body, for example, during digestion or urination. Smooth muscles in the gastrointestinal or GI tract control digestion. The GI tract stretches from the mouth to the anus. Food moves through the digestive system with a wave-like motion […]
What is the color of andesite rock?
What is the color of andesite rock? Andesite is the volcanic equivalent of diorite. Group – volcanic. Colour – variable, but typically bluish-grey or grey (lighter coloured than basalt). What type of rock is andesite? Andesite is a volcanic rock. It is fine-grained because it forms by the rapid cooling of magmas usually when it […]
