Does doubling a objects average speed always double the magnitude of its displacement?
first of all the question should come with velocity instead of speed. it doesn't necessarily mean that displacement is doubled the time in which the object makes that displacement is halved
When L is doubled and C is halved the resonance frequency of series tuned circuit becomes?
The same
What happens to speed if kinetic energy halved?
Kinetic energy is determined by mass and velocity. The velocity is halved if you double the original mass, so the kinetic energy stays the same (unless the mass added has the same kinetic energy in the observer's reference frame as the original mass).
How does the gravitional force change if theier mass are halved?
If the masses of two objects are each halved, and the distance between them doesn't change, then the mutual gravitational forces of attraction between them are reduced to 1/4 of their original magnitude.
What happens to the potential energy of an object if the mass is halved?
I assume you mean the gravitational potential energy. This is proportional to the mass, so if you change the mass by a factor of "a", the gravitational potential energy will change by the same factor of "a".

What is the density of a nickel if it were sawed in half?
It is unchanged. The density is the mass divided by the volume, and as both of these numbers are halved the density does not change.

What will happen to the kinetic energy of the body if the mass of the body is halved and velocity remains the same?
Kinetic energy will also be halved. Because kinetic energy is equal to 1/2 mv2
What happens to the volume of a gas - if the temperature of the gas decreases?
V=RT/p so it depends on how much the decrease is: if both are halved then volume is unchanged!
How does the kinetic energy of a body change if its momentum is halved?
Since momentum is proportional to the velocity, half the momentum means half the velocity (and therefore half the speed). And since kinetic energy is proportional to the SQUARE of the speed, half the speed means 1/4 the kinetic energy.

How much of a 100-g sample of thorium-234 will be unchanged after 48.2 days?
25 gExplanation:Think about what a nuclear half-liferepresents, i.e. the time needed for an initial sample of a radioactive substance to be halved.
What would be the momentum if the mass were halved?
momentum=mass * velocity if velocity remain unchanged, the momentum too will be halved ============================================== But wait! Haven't we all learned that momentum is conserved, and half of it doesn't just suddenly disappear ? If half of the mass of a moving object suddenly disconnects from the object and goes somewhere else, then half of the momentum must go along with that half of the mass, and the total momentum doesn't change. On the other hand, if Tinker-Bell flew by, waved her magic wand and sprinkled ferry dust on the moving object so that half of its mass truly ceased to exist, then in order to keep the total momentum constant, the object's velocity must double! The answer to the question is: No matter what happened to the massive moving object, or how it happened, total momentum doesn't change. It's the same today, tomorrow, and forever. Momentum of the total system is always conserved. If half of the mass is detached, you can't say the rest is the whole system. The whole system is together both halves. If both moving same velocity, momentum is divided. If that half stopped, half of the momentum goes to the force used to stop that.
