A car travels 400 km in 5 hours. what is the average speed of the car (in km/hr) ?
PtichkaEL [24]
Distance travel = 400km
Time it took to travel 400km = 5 hr

Average speed = (distance travel)/(Time for that travel)

s = 400km/5h = 80km/hr

The average speed is 80km/hr.

A 200g of iron at 120 degrees and a 150 g piece of copper at -50 degrees are dropped into an insulated beaker containing 300 g o
kodGreya [7K]

Answer:

T = 15.03°C

Explanation:

given data:

copper specific heat = Sc = 0.385 J/g °C

iron specific iron = Si = 0.450 J/g °C

specific heat of ethanol = Se = 2.46 J/g °C

net heat loss is equal to zero

(m*S*\Delta T)_{copper} +(m*S*\Delta T)_ {iron} +(m*S*\Delta T)_ {ethanol} = 0

150*0.385 *( T - (-50)) + 200*0.450*(T - 120) + 300*2.46 * (T -20) = 0

57.75( T - (-50)) + 0.90(T - 120) +738(T -20) = 0

57.75T + 2887.5 + 0.90T - 108 + 738T - 14760 = 0

57.75T + 0.90T+738T = - 2887.5 + 108+14760

796.65T= 11980.5

T = 15.03°C

The refracting telescope at the Yerkes Observatory has a 1.00-m diameter objective lens of focal length 20.0 m. Assume it is use
igomit [66]
Angular magnifiction=m= \frac{ f_{0} }{ f_{e} }
f_{0}==focal length of object lens=20m
f_{e}=focal length of eye lens=1.90 m
so magnification=m=20/1.9=?
