Answer:
the heat loss from this insulated wire is less
Explanation:
Given data in question
diameter of cable (d) = 20 mm
( K ) = 1 W/m-k
heat transfer coefficient (h) = 50 W/m²-K
To find out
the heat loss from this insulated wire
solution
we will find out thickness of wire
heat loss is depend on wire thickness also
we have given dia 20 mm
so radius will be d/2 = 20/ 2 = 10 mm
Now we find the critical thickness i.e.
critical thickness = K / heat transfer coefficient
critical thickness = 1 / 50 = 0.02 m i.e. 20 mm
now we can see that critical thickness is greater than radius 10 mm
so our rate of heat loss will be decreasing
so we can say our correct option is (a) less
Answer: T= 159.3N
Explanation:
The total Tension on the rope at this point=
Sum of the weight of the ball + the centripetal force on the ball
T= W+ mv^2/r
Where T is tension, W is weight of the ball, m is mass of the ball, r is radius of rotation, v is the velocity of rotation. g= acceleration due to gravity
W= 100N
m= W/g= 100/9.8 = 10.2kg
v= 5m/s
r= 4.3m
Therefore,
T= 100 + 10.2×5^2/4.3
T= 100 + 59.3
T= 159.3N
Answer:Gas particles spread out to fill a container evenly, unlike solids and liquids. Gas is a state of matter that has no fixed shape and no fixed volume.A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure.Liquid is the state in which the substance takes the shape of its container but has a definite volume.
