how many calories of energy are given off to lower the temperature of 100.0g of iron from 150.0°C to 35.0°C?
jeyben [28]

Answer:

ΔT = Tfinal − Tinitial = 150°C − 35.0°C = 125°C

given the specific heat of iron as 0.108 cal/g·°C

heat=(100.0 g)(0.108 cal /g· °C )(125°C) =

  100x 0.108x125= 1350 cal

Total distance divided by total elapsed time gives what quantity?
ki77a [65]
<h2>Total distance divided by total elapsed time gives : Average speed </h2>

Explanation:

Speed

It is the distance traveled by body with respect to time .

Its formula is Speed = distance /time

V=S/T

units : m/sec or Km/hr

Distance

It is total path traveled by body in any direction .

It unit and symbol is : S  and unit = m /Km

Average speed

It is the total distance traveled by body with respect to total time taken to travel that given distance .

Average speed = total distance /total time

A.s = T.D/T.T

unit = m/sec or Km/hr

Instantaneous velocity

It is the distance traveled by body at particular instant of time ,in given direction .

Displacement

It is the shortest path traveled by body in given direction .

borishaifa [10]

Explanation:We have momemtum = mass X velocity

    p = mv

    OR, p/m = v

    v = (125kg m/s)25kg

    v = 125/25 m/s

       v = 5 m/s
