Answer: (a) 99.5℅ submerged
(B) 96.9℅ submerged
Explanation:
For 995 kilograms per cubic meter, It'll be the 995Kg/m3 density given, divided by the density of fresh water, which is one times ten to the three kilograms per cubic meter, and this works out to 99.5 percent submerged.
If the same person with the same density was floating in salt water, salt water has a slightly higher density of 1027 kilograms per cubic meter, this works out to 96.9 percent submerged.
Explanation:
The five basic postulate of kinetic molecular theory includes:
1) All gases consist of large amount and numbers of tiny particles that are far apart from each other and also relative to their size.
2) The collisions between gas particles and gas particles against container walls is refer to as elastic collision.
3) All gas particles are in a continuous random and rapid motion. They possess kinetic energy which is energy of motion.
4) There are no attractive force between gas particles.
5) The temperature of a gas depends on the average kinetic energy of the gas particle.
Answer:
2 L, L, 2 L/3
Explanation:
For a pipe of length l open at both ends, the length of the pipe is given by :
or
For first pitch tone, n = 1
For first pitch tone, n = 2
For first pitch tone, n = 3
So, the wavelengths of the three lowest-pitch tones produced by this pipe are 2 L, L, 2 L/3 respectively. Hence, the correct option is (d)
F=G*(M*m)/r^2
If you double the diameter, you double the radius. So this means r^2 is now (2*r)^2.
If you quintuple it's mass, you multiple M by 5. So M is now 5*M.
Now your equation is:
F=G*(5M*m)/(2r)^2
or
F= 5 G*(M*m)
------------------
4 r^2
so your answer is F (the force due to your mass and gravity or "weight") would change by a factor of 5/4!
F2= 5/4*F1 OR Weight (From New Earth) = 5/4*Weight(from old earth)
