Answer: Option (B) is the correct answer.
Explanation:
Surface tension is defined as the attractive forces experienced by the surface molecules of a liquid by the molecules present beneath the surface layer of the liquid.
And, viscosity is defined as the ability of a liquid to resist its flow. When a substance has high viscosity then it is known as a viscous substance.
Since, it is given that viscosity of liquid B is more than liquid A. Therefore, liquid B has more resistive force on its surface as compared to liquid A. As a result, time taken by liquid B is more than time taken by liquid A.
Also, Surface tension =
Surface tension of liquid B is more than liquid A. Therefore, .
Thus, we can conclude that tA will be less than tB.
An electric motor produces heat while running. The amount of heat is roughly equivalent to the amount of power delivered to the motor.

Numbers above zero are significant, as well as any zeros that appear in between two non-zero numbers.
Answer:
The products are SnPO4 and LiC2H3O2
Explanation:
The reactants are LiPO4 + Sn(C2H3O2)2
This is a double replacement reaction
So what you do is switch the elements the other way around.
To do that, all you have to do switch Sn with PO4 since Sn is a cation and PO4 is an anion.
Then you switch Li with C2H3O2 because Li is a cation and C2H3O2 is an anion.
After that, check the charges. PO4 has -3 charge
So just leave Sn the way it is without a subscript.
In word form, the product would be Tin(III) Phosphate
C2H3O2 has a -1 charge Li has a +1 charge
So leave both of them the way it is without any subscripts.
In word form, the product would be Lithium Acetate
