Answer:
Half as much as it was
Explanation:
According to Charles law
PV = k
P is the pressure
V is the volume
If PV= k, then P1V1= P2V2
P1 and P2 are the initial and final pressure respectively
V1 and V2 are the initial and final volume respectively
Given
V1 =11.2litres
P1 = 0.860atm
If the volume is doubled, V2 = 2(11.2) = 22.4litres
Get P2
P2 = P1V1/V2
P2 = 0.860×11.2/22.4
P2 = 0.860/2
P2 = P1/2 (since P1 =0.860)
P2 = 1/2 P1
Hence the pressure becomes halved if the volume is doubled
Answer:
200 m North
Explanation:
1. Let's represent north as positive and south as negative.
(100 m)+(-200 m)+(300 m)
= 200 m
2. Since the answer is positive, the units are 100 m NORTH since north represents positive.
Answer:
B
Explanation:
Current is only measured in Amperes.
D makes little to no sense and I believe A somewhat relates to static electricity, not current.
No. For one thing, when it comes, it flows too fast to catch it and store it. And second, you never know WHERE to set up your equipment.
F = m × g
Now when, a force acts on the object at an angle and in downwards, thus formula becomes:
= N = mg + F sin(x)
Here,
- N = normal force, m = mass , g = acceleration due to gravity, F = outside force, x = the angle formed
See, as we habe to calculate the weight, which is m × g, thus we will recreate thus formula like thus:
= N = w + F sin(x) --------- [Weight = w]
Now, the solutions becomes easy from here, just put the values:
= N = w + F sin(x)
= 200 = w + 90 × sin(32)
= 200 = w + 90 × 0.55
= 200 = w + 49.5
= 200 - 49.5 = w
= 150.5 = w
I have got my answer but in approx, hope you will not mind. ^^"
