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
T = 15.03°C
Answer:
a) Volume = 2/3 r³
Volume = 2/3 × 22/7 × 14 × 14 × 14 = 5749.3 cm³
b) Total surface area = 3r²
Area = 3 × 22/7 × 14 × 14 = 1848 cm²
Answer:
68.2 Quadrillion meters
Explanation:
A lightyear is the distance that light travels in one year.
Speed of light is
So light covers 300,000,000 meters in one second.
One year has 31536000 seconds so , light covers
so 7.2 light years is
so 7.2 light years is
6.82 x 10^(16) meters or
68.2 Quadrillion meters
