Answer:
Typing gradually gets easier by the day, coding gradually can become harder, where as reading needs focus and potential. I'd say Coding
Explanation:
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:
The speed is minimum at t = 4 seconds.
The position function of a particle is given by
The velocity is given as,
Speed is computed as,
Differentiate above expression and equate to zero.
Thus, speed is minimum at t = 4 seconds.
