If Laura travels d d km along the circular ski trail, then the angle subtends an arc d 1.4 d1.4 radius lengths long (starting at the 3-o’clock position) and hence the angle has a measure of d 1.4 d1.4 radians. Recall that we can use this information to determine Laura’s position relative to the center of the ski trail using the sine and cosine functions.

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
