Answer:
63.8 kJ
Explanation:
The net work output per cycle is the difference in heat input and heat output. The heat input and heat output are expressed as a function of volume ratios, while volume is expressed as a function of pressure and pressure as a function of temperature.
R = 287 J/kg.K, k = 1.4
Hence the net work input (W) is given as:
The penny sank when the boy threw the coin into the fountain because the density of the penny is more than the density of the water.
Option B
<u>Explanation:</u>
Density is the physical property which relates mass and volume of an object. The equation format for density is given as follows:
When the density of an object is more obviously it tends to weigh heavier than the lighter objects. Coin being made of metal is naturally heavier and has more density than water. Denser objects tend to sink in liquids less denser than the objects. Hence, coin sinks in water fountain.
The Ammeter shows: I = 15 A,
The circuit resistance is R = 0.2 Ohms.
By the Ohm`s Law:
R = V / I or:
V = I · R
V = 15 A · 0.2 Ohms
V = 3 V
Answer: C ) 3 V.
Mass would be 104/1.16 = 89.66 kg
Weight on Earth would be 89.66 * 10 = 896.55N
Weight on Mars 89.66 * 3.7 = 331.72 N
I would say because they have the same negative charge and they repel each other
