<span>A 50 kg student runs up a flight of stairs that is 6 m high. How much work is done? 3000 J. Calculate the work done when a force of 1 N moves a book 2 m. 2 J .... 200 W, 100 W. Calculate the power expended when a 500. N barbell is lifted 2.2 m in 2.0 seconds. 550 W. energy. the property of an object or system that ...</span>
Answer : 0.125 M
Explanation : The definition of osmotic pressure is "<span><em>the pressure can be applied on a pure solvent to prevent it passing into a given solution by osmosis</em>".
</span>
So according to this definition, osmotic pressure can be called as directly proportional to the concentration of the solution and hence the pressure can also be directly proportional to the concentration.
Hence, if pressure is getting decreased from 28 to 7 it means it got decreased by 4 times;
28 / 7 = 4 that means;
So the concentration will be also decreased by 4 times so, 0.50 / 4 = 0.125 M
Explanation:
(1) 1 m = 100 cm
1.45 m = 100 × 1.45 cm = 145 cm
(2) 1 kg = 1000 g
325 g = 0.325 kg
(3) 1 L = 1000 mL
0.0024 L= 2.4 mL
(4) 1 km = 1000 m
(5) 1 mm = 0.001 m
(6) 1 kg = 100000 cg
0.459 kg = 45900 cg
(7) 1 dm = 10⁻⁴ dm
5,995 dm = 5,995 × 10⁻⁴ km
(8) 1 g = 1000 mg
450 g = 450000 mg
(9) 1 dm = 100 m
0.003 dm = 0.3 mm
(10) 1 mL = 0.001 l
4.567 × 10⁴ mL = 45.67 L
Answer:
.Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.
Explanation:
The transfer of thermal energy is called heat. In this process, thermal energy moves through a substance. For example, an ice cube has heat energy and so does a glass of lemonade.
