Answer:
Because the force one needs to apply is reduced.
Explanation:
- Work can be expressed in terms of force and distance as follows,
Work = Force × distance
- To be more precise, the selection of these two parameters should be in a manner that the distance is what the line of action of the force traces.
- It is obvious that for a given amount of work when one parameter is changed the other changes to counteract the change of the first one.
- Imagine the situation shown in the attached figure. The amount of work that needs to be done during the lifting of the mass to a height of
vertically is
. - On the slope, however, one needs to push the object an
distance up to get the object to that
height ultimately. - The work he does on the slope is
and since
,
. - The force that needs to be applied is less than that applied in the vertical lift. Hence it feels easier. #SPJ4
So in your question where ask to find the dipole moment of HI in C.M. So in my calculation by converting the given data from Debyes to Coulomb Meteres is that 1 Dyebes is equals to 3.33X10^(-30) C.M and the answer would be 1.40X10(-30)C.M. I hope you are satisfied with my answer and feel free to ask for more
Answer:
In the table, 1=46.7 °C, 1=165 J, 2=819 J, 3=1510 J, and 4=2830 J.
Other experiments determine that the material has a temperature of fusion of
fusion =235 °C and a temperature of vaporization of vapor=481 °C.
If the sample of material has a mass of =8.60 g, calculate the specific heat when this material is a solid, and when it is liquid, l
Answer:
Apply the following formulae horizontally And get A value for time
Remember horizontal acceleration is zero

and then to find the height apply the same above equation vertically...remember vertical initial velocity is zero

Answer:
vpg = 0.064 N
Explanation:
Upthrust = Volume of fluid displaced
upthrust liquid on the cube g=10ms−2
vpg =0.2 x 0.2 x 0.2 x0.8 x 10= 0.064N
vpg = 0.064 N
hope it helps.
