Answer:
230 torr
Explanation:
Given that
P = 230 mm of Hg
If argon gas and mercury is in equilibrium position then the pressure on the both side will be same .
As we know that
1 torr = 1 mm of Hg
So the pressure of the argon will be 230 torr .
Unit conversion
1 torr = 1 mm of Hg
1 bar = 100 KPa = 10⁵ Pa = 10⁵ N/m² = 0.1 MPa = 0.1 x 10⁶ Pa
Answer:
(a)
M = 1.898 x 10^27 kg
(b)
v = 13.74 km/s
(c) E = 0.28 N/kg
Explanation:
Time period, T = 3.55 days = 3.55 x 24 x 3600 second = 306720 s
Radius, r = 6.71 x 10^8 m
G = 6.67 x 10^-11 Nm^2/kg^2
(a) 
M = 1.898 x 10^27 kg
(b) Let v be the orbital velocity
v = 13739.5 m/s
v = 13.74 km/s
(b) The gravitational field E is given by
E = 0.28 N/kg
You can make sure there's no change in volume by keeping
your gas in a sealed jar with no leaks. Then you can play with
the temperature and the pressure all you want, and you'll know
that the volume is constant.
For 'ideal' gases,
(pressure) times (volume) is proportional to (temperature).
And if volume is constant, then
(pressure) is proportional to (temperature) .
So if you increase the temperature from 110K to 235K,
the pressure increases to (235/110) of where it started.
(400 kPa) x (235/110) = 854.55 kPa. (rounded)
Obviously, choice-b is the right one, but
I don't know where the .46 came from.
Answer:
A. 20 N
Explanation:
the weight of book is 2×10= 20N
Answer:
Frequency
Explanation:
The intensity of light is increased by increasing the number of photon per second, and the number of photon per second is referred to as frequency. A photon the smallest unit of light. If the frequency is increased, the number of photons per second increases hence an increase in intensity.
