Answer:
No, both the thermometers will give the different reading.
Explanation:
Given,
- Both thermometer has same ice point =
- Both thermometer has same steam point =
- Distance between the ice point and steam point in both the thermometer is same of 100 division,
All the data given in both the thermometers are same, but the material in the thermometer is different due to this the reading at 60^o C will differ in both the thermometer. Because the reading on both the thermometer is depended upon the thermal expansion of the material inside it, but both the materials are different. Due to this the rise of fluid in the thermometer, i,e,. the volume of the fluid material in the thermometer will depend upon the thermal expansion. Hence both the material alcohol and mercury have the different thermal expansion, therefore the rise of the fluid in the thermometer also differ in both the thermometer.
Answer:
Explanation:
Electric field strength= Force/unit charge
E= (kQq/r²)/q ₓ r
where r is the unit vector in the direction of unit charge
E=
Answer : The rate of heat transfer to the water is, 37.92 kJ/min
Explanation : Given,
Time = 10 min
Mass of water = 200 g
Latent heat of fusion of water = 334 J/g
Latent heat of vaporization of water = 2230 J/g
Now we have to calculate the rate of heat transfer to the water.
Now put all the given values in the above formula, we get:
Thus, the rate of heat transfer to the water is, 37.92 kJ/min
Answer:
Comet Tail
Explanation:
A comet tail— and coma — are characteristics that are evident in comets when the Sun illuminates them and can become apparent from Earth when a comet travels through the inner part of the Solar System.
While a comet enters the inner part of solar system, sunlight causes the toxic materials inside the comet to vaporize and float out of the center, sweeping away particles with them.
Two, distinct tails are created from dust and gases, being visible by different occurrences; the dust simply reflects sunlight, and the gasses shine through ionization.
Answer:
755.7 seconds
Explanation:
Distance between Sun and Mars = 226.71 * 10^9 m
Speed of light = 3 * 10^8 m/s
Speed = distance/time
Time = distance/speed
Time = (226.71 * 10^9)/(3 * 10^8)
Time = 755.7 s
