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.
In order for two vectors to add to zero, they must have the same magnitude and point in opposite directions.
Two perpendicular vectors, by definition, make a right angle with each other whereas two vectors pointing in opposite directions form a straight line.
Because of this, two perpendicular vectors with nonzero magnitudes will never add to zero.
The answer is 5 because you divide 25 by 5
Answer:
The cork:
C) floats at the same height
Explanation:
The law of floatation states that an object will float when it displaces its own weight of fluid in which it floats e.g. the weight of the object is equal to the displaced liquid. With this definition it is clear that the cork will float at the same height because the evacuated air has little or no effect on the cork floating on the surface of the incompressible liquid.
Answer:
Torque, 
Explanation:
It is given that,
Length of the wrench, l = 0.6 m
Mass of the wrench, m = 100 kg
We know that the torque applied by mechanic is given by :
So, the torque applied by the mechanic is 588 N-m. Hence, this is the required solution.
