Below is the solution:
W done by Normal = 0. (make the incline flat, Normal force goes directly up: no work done)
<span>W done by gravity = w*displacement = (11kg*9.8) * 7.5sin(35) = -463J </span>
<span>W done by friction is the opposite of the work done by weight because the object is not moving. Therefore W done by friction = 463J</span>
Answer:
Two possibities: Increase in pressure or decrease in temperature.
Explanation:
There are two possibilities under the assumption that mass of the gas is conserved and, consquently, the amount of moles is also conserved, a reduction in the volume of the gas leads to an increase in pressure (Boyle's Law) and a decrease in temperature (Gay-Lussac's Law)
Answer and Explanation
It was initially specified that the receptacle outlet to be located within 50 ft of the electrical service equipment.
As well, instead of the receptacle being required within 50 ft., it is now required within 25 ft. of the service. This was to accommodate the typical 25 ft. cord used by many service electricians.
The rules apply to indoor service locations other than one-and two-family dwellings. For these locations, at least one 125-volt, single-phase, 15- or 20-ampere receptacle outlet must be installed in an accessible location within 25 ft. of the indoor electrical service equipment. The receptacle must be within the same room or area as the actual service equipment.
Having a maintenance receptacle near the electrical service allows for testing, servicing and connection of portable electrical data acquisition equipment for analyzing the electrical system.
Answer: 7.25 * 10^5
Explanation:
1. The equation simplifies to (7*10 + 2.5) 10000.
2. Simplify in the parenthesis. 72.5 * 10000.
3. In scientific notation, the answer is 7.25* 10^5.
Waves transfer energy over distance without moving matter the entire distance. So your answer would be energy.
