If we measure temperature in degrees celsius and time in minutes, the constant of proportionality k equals 0.4. suppose the ambient temperature ta(t) is equal to a constant 84 degrees celsius. write the differential equation that describes the time evolution of the temperature t of the object.

Explanation:

dT = Change in temperature

dt = Time interval

k = constant of proportionality = 0.4

= Temperature of object

= Temperature of ambiance = 84°C

From Newton's law of cooling we have the expression

So, the differential equation is

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
