Answer:
Explanation:
Work done (J) = Force (N) × Distance (m)
<em>W</em> = 400 × 30
<em>W</em> = 12000
The work done is 12000 J.
Answer:
always same
Explanation:
velocity and speed are same upto some extend but velocity is vector while speed is scalar quantity
Answer:
a) 425.6 K = 152.6 degree Celsius
b) 678.6 square centimeter
Explanation:
Initial enthalpy = Final enthalpy
m(h1 + v1^2/2) = m(h2 + v2^2/2)
(h1 + v1^2/2) = (h2 + v2^2/2)
h 2 = (h1 + v1^2/2) - (v2^2/2)
h 2 = 400.98 + (230^2 – 30^2)/2 * 10^-3
= 426.98 KJ/Kg
T2 = T1’ + (T2’ -T1’)(h2-h1’)/( h2’-h1’)
T2 = 420 + (430-420)(431.43-421.26)(426.98-421.26)/(431.43 – 421.26)
T2 = 425.6 K = 152.6 degree Celsius
Area = mRT2/P2V2
Area = (600/60*60*1) *0.287*425.6/(100*30) *10^4
Area = 678.6 square centimeter
Answer:
163.5m
this is how far the doggo would go
(In theory)
If I'm wrong I apologize
