All the tools & learning materials you need for study success - in one app.
Get started for freeExplain the important distinctions between each pair of terms: (a) mass and weight; (b) intensive and extensive properties; (c) substance and mixture; (d) systematic and random errors; (e) hypothesis and theory.
Express each value in exponential form. Where appropriate, include units in your answer. (a) speed of sound (sea level): 34,000 centimeters per second (b) equatorial radius of Earth: 6378 kilometers (c) the distance between the two hydrogen atoms in the hydrogen molecule: 74 trillionths of a meter (d) $\frac{\left(2.2 \times 10^{3}\right)+\left(4.7 \times 10^{2}\right)}{5.8 \times 10^{-3}}=$
