Explanation:. The vending machine holds 10 bags of pretzels and 8 packs of cheese crackers. Both the pretzels and crackers dispenseat 2 bags per hour. How many hours will elapse when there is the same number of snacks remaining in the vending machine? How many of each item will there be at this point?Equation1______________________________Equation2_______________________________Hours: ___________________________ Items: ____________________________What does each equation have n common? ______________________How does this affect the solution?
Answer:
0.0365 A
Explanation:
Data provided in the question:
Peak value of the voltage, V = 17.0 volts
Resistance of the resistor, r = 329.0 ohm
Now,
The rms current () is given by the relation as:
on substituting the respective values, in the equation, we get
or
= 0.0365 A
Hence, the rms current is 0.0365 A
Answer:
D = 26.97 m
Explanation:
given,
you walk 12.5 m in a direction exactly 19° south of west
after that 19.5 m in a direction exactly 39° west of north.
distance calculation from the starting point = ?
D₁ = d₁ cos θ
D₁ = 12.5 x cos 19°
D₁ = 11.82 m
D₂ = d₂ cos θ
D₂ = 19.5 x cos 39°
D₂ = 15.15 m
distance from the starting point
D = D₁ + D₂
D = 11.82 + 15.15
D = 26.97 m
Distance from the starting point is equal to 26.97 m
Answer:
carbon dioxide is turned to oxygen
Explanation:
because carbon and oxygen are bonded together to form a molecule therefore in order to separate them a chemical reaction would be required
Answer: The correct explanation is 2.
Explanation: The warm air is less dense (it expands) and thus it is lighter than the cold air so it will rise up to the floor. Therefore, when you place the heater on the floor it will warm the cold air which would then rise and be replaced by more cold air which would again get warm and rise and so on until the room is heated. This means that the correct explanation is 2.
On the other hand, if you put the heater at the ceiling, it will warm the cold air near the ceiling which would stay up there (it is lighter than the cold air under it). This means that the only way for the heat to spread from this ceiling level warm air to the lower levels is via conduction which is slow.
