(Q).
Answer the following question given this paragraph: In physics, resistance is opposition to the flow of electric charges in an electric current as it travels through matter. The SI unit for resistance is the ohm. Resistance occurs because moving electrons in current bump into atoms of matter. Resistance reduces the amount of electrical energy that is transferred through matter. That's because some of the electrical energy is absorbed by the atoms and changed to other forms of energy, such as heat. You can see an animation of resistance at the level of atoms and electrons at this URL: http://www. physics. org/explorelink. asp?id=1738&q=electricalresistance&currentpage=1&age=0&knowledge=0&item=3. Q: In physics, resistance is opposition to the flow of what? Choices: - temperature charges - capacitance - surface flow - electrical charges A:
(A).
electrical charges
Ques:Answer the following question given this paragraph: In a wheel and axle, force may be applied either to the wheel or to the axle. This force is called the input force. A wheel and axle does not change the direction of the input force. However, the force put out by the machine, called the output force, is either greater than the input force or else applied over a greater distance. Q: What is the term for the force applied to a wheel and axle? Choices: - velocity force - momentum - output force - input force A:

Ans:input force
Question: Answer the following question given this paragraph: Some fungi have a different kind of relationship with plants. They are plant parasites. They get food from the plants and cause harm to the plants in return. Fungi are the major causes of disease in agricultural crops. They may eventually kill their plant hosts. Q: What is the major cause of disease in agricultural crops? Choices: - bacteria - drought - pollution - fungi A:
Answer:
fungi
