Last year an average life span of 69 years with standard deviation of
8.9 years was shown by a random sample of 100 recorded deaths in
the Philippines. Using 0.05 level of significance does it seem to show
that the average life span today is greater than 72 years?
From the knowledge that CV, the molar specific heat at constant volume, for a gas in a container is 5.0R, calculate the ratio of the speed of sound in that gas to the rms speed of the molecules,
for gas temperature T.

The temperature of a 0.700 kg cube of ice is decreased
to -150 C. Then energy is gradually transferred to the cube as
heat while it is otherwise thermally
isolated from its environment. The
total transfer is 0.6993 MJ. Assume
the value of c for ice given
is valid for temperatures from
-150 C to 0 C. What is the final
temperature of the water?
Hello,
I've oxidated lead using electrolysis. I think it should be lead (iv) oxide ( I use 10 V power source and the color of the product is like color of Fe2O3). now I want to make lead (ii,iv) of it.
I've tryed heating it in a plate but it doesn't work. what should I do?
The electric field has a magnitude of 3.0 N/C at a distance of 60 cm from a point charge..What is the charge?
The tension in a string holding a solid block below the surface of a liquid (of density
greater than the block) is T0 when the container is at rest. When the container is given an upward acceleration of 0.250g, what multiple of T0 gives the tension in the string?
