Answer the following question given this paragraph: The angular momentum of a spinning object can be found in two equivalent ways. Just like linear momentum, one way, shown in the first equation, is to multiply the moment of inertia, the rotational analog of mass, with the angular velocity. The other way is simply multiplying the linear momentum by the radius, as shown in the second equation. Q: Multiplying the linear momentum of a spinning object by the radius calculates what? Choices: - applied momentum - angular torque - total momentum - angular momentum A:
angular momentum

Answer the following question given this paragraph: Matter can exist in one of several different states, including a gas, liquid, or solid state. States of matter differ in the amount of energy their molecules have. When matter recycles, it changes state by gaining or losing energy. Q: When matter recycles and changes state what does it gain or lose by doing so? Choices: - density - volume - fuel - energy A:
energy

Answer the following question given this paragraph: Muscle tissue is made up of cells that have the unique ability to contract, or become shorter. Muscles attached to bones enable the body to move. Q: What type of tissue is made up of cells that have the unique ability to contract? Choices: - connective tissue - epithelial tissue - nervous tissue - muscle tissue A:
muscle tissue

Answer the following question given this paragraph: Cells divide repeatedly to produce an embryo. Previously the one-celled zygote (the first cell of a new organism) divided to make two cells (a). Each of the two cells divides to yield four cells (b), then the four cells divide to make eight cells (c), and so on. Through cell division, an entire embryo forms from one initial cell. Q: What do you call the first cell of a new organism? Choices: - embryo - starter cell - egg - zygote A:
zygote
