A uniform steel plate has an area of 0.819 m2. When subjected to a temperature difference between its sides, a heat current* of

Tju [1.3M]

Answer:

ΔT / Δx = 771 K/m

ΔT = 771 x 0.0475 = 36.62 k

Explanation:

P = 31700 W, A = 0.819 m^2, Δx = 0.0475 m, K = 50.2 W /m k

Use the formula of conduction of heat

H / t = K A x ΔT / Δx

So, ΔT / Δx = P / K A

ΔT / Δx = 31700 / (50.2 x 0.819)

ΔT / Δx = 771 K/m

Now

ΔT = 771 x 0.0475 = 36.62 k

Susan goes out to exercise. She runs for one hour at a constant speed and velocity. What is the overall net force acting on Susa

kiruha [24]

Option (A ) is correct.

Explanation:

susan is moving with constant velocity, so both the direction and magnitude of the velocity remains same. so the acceleration of susan =0. This is because an object gets accelerated when either the magnitude or direction of the speed changes.

now the force is given by

$F= ma$

F= force

m= mass

a= acceleration

Here a =0

so F= 0

so the net force on susan is zero.
