Answer:
The one at the front is the driver. he one at the back is the brakeman.
Explanation:
In either a two or a four person bobsled team, the one at the front of the sled is called driver. The one at the back is called the brakeman, and is the one that pushes the back of the sled. The brakeman is the one that jumps in last as the sled gains speed.
In case of the four person, the other two team participants are just referred as riders.
Answer:
Kepler's laws apply: First Law: Planetary orbits are elliptical with the sun at a focus. Second Law: The radius vector from the sun to a planet sweeps equal areas in equal times. Third Law: The ratio of the square of the period of revolution and the cube of the ellipse semimajor axis is the same for all planets.
Answer:
I = 0.058 [A]
Explanation:
Ohm's law is defined as voltage equal to the product of current by resistance.
where:
V = voltage = 4.2 [V]
I = current [amp]
R = resistivity = 72 [ohm]
Now clearing I, we have:
Answer:
D: Water is polar, so it can form attractions to and pull apart molecules of many types of substances.
Explanation:
Water is an excellent solvent simply because its polar water molecules usually form hydrogen bonds with ions and polar molecules, thereby allowing the ionic and polar covalent compounds to easily disperse easily in water.
Thus, the correct option is; D
Answer:
the answer is equal to yes
