Answer:
Explanation:
velocity=s/t
given distance is 480 km we have to convert it into meter because the unit of distance is meter
1 km=1000 m
480 km=480000 m =4.8*10^5
1 hour= 3600 s
12 hour =43200 s
now velocity=s/t
v=4.8*10^5/43200
v=11.11 m/s
I think it’s output because output work is work done by a machine
Answer: You may hurt yourself or fail
Explanation: If you do not follow the steps right you might end up only hurting yourself or embarrising youself in front of others. You don't want to fail and then you just keep doing it over and over.
Hope this helps^^
Answer:
160 days
Explanation:
Using the equation
rA^3/TA^2 = rB^3/TB^2
Where rA is radius of Moon A = R
TA is Time for moon A complete one orbit = 20 days
rB is radius of Moon B =4R
TB is Time for moon B complete one orbit = ?
Therefore
rA^3/TA^2 = rB^3/TB^2
R^3/20^2 = (4R)^3/TB^2
Cross multiply to solve for TB, then we have
TB^2 × R^3 = (4R)^3 × 20^2
TB^2 × R^3 = 64 × R^3 × 400
TB^2 × R^3 = 25600 × R^3
Divide both sides by R^3
TB^2 = 25600
Square root both sides
TB = sqrt 25600
TB = 160days
Answer:
The outlet velocity is 159.9m/s
The outlet temperature = 290.6K
Explanation:
At initial condition
P=2 MPa
T=30°C
V=25 m/s
At final condition
P=0.3 MPa
Now from first law for open system
We know that for air
h= 1.010 x T KJ/kg
Now from mass balance
Now from equation 1 and 2
So we can say that
The outlet velocity is 159.9m/s
Now by putting the values in equation 2
The outlet temperature = 290.6K
