What happens to:
1.KINETIC ENERGY if
a) mass is doubled
b) mass is made half
c) velocity is doubled
d) velocity is made half
2] POTENTIAL ENERGY IF
c) height is doubled
d) height is reduced to half
PLEASE ANSWER THIS AS SOON AS POSSIBLE I HAVE A EXAM TO WRITE TOMORROW. DEAR EXPERTS I NEED YOUR HELP. please
If the unit of mass is doubled ,and the units of length and time are halved ,how much is 20 N force in new units ? (1N=1Kgm/s2)
what is thermal power plants
how can electric current be maintained through a conductor?
explain 3 application(daily life) of pressure with diagrams
help me out
Water waves produced by a motor boat sailing in water are---
a. neither longitudinal nor transverse.
b. Both longitudinal transverse
c. only longitudinal.
d. Only transverse
We know the fact that any object located at a height with respect to a certain reference level is said to possess energy called gravitational potential energy. This energy depends on this reference level (sometimes also referred as ground level or zero level). When a ball is taken to the top floor from the ground floor, it acquires some gravitational potential energy. When this ball was dropped from a height h1 on the top floor, the zero level is the top floor itself. When the ball was dropped from a height h2 on the ground, the zero level is the ground. Since the distance covered by the ball was greater in the second case, i.e. h2 > h1, it rebounded to a greater height from the ground than that from the top floor.then y if the ball was dropped with force it would rebond 2 a greater height the lenght between ground level andand top floor being same in case....

In More about energy , in renewable and non renewable sources there is a sentence, "About 13 percent of the primary energy comes from renewable resources". what does it means
mention any three ways of storage of radio active materials and disposal of radio active waste .
DO the electrons in atom follow the law of conservation of energy?PLEASE EXPLAIN that how it happens.
what is anthracite
What would be the velocity of a plane with a speed equal to that of sound?
why a single solar cell cannot run a device
true/false
a)Force of friction icreases if the two surfaces are pressed harder.
b)Sliding or kinetic friction is smaller than the limiting value of static fraction.
c)Friction increases with height.
define electric potential of a charged body.
In the Chapter "More About Energy" ,
it's given that- a piece of paper catches fire when sunlight is made to fall on it through a convex lens , due to the Light Energy of the Sun.
How could Light Energy be responsible for raising the Temp. of Paper above it's Ignition Temperature : not the Heat Energy ?
is the difference between fission and fussion
Bring a magnet near an iron nail. What do you notice? The iron nail gets attracted towards the magnet and starts moving. You already know that movement means kinetic energy. But from where does the kinetic energy come to the nail?
which of these is a better form of nuclear reaction -nuclear fusion or nuclear fission
how do turbine rotate ?
what is carbonization
differenciate betwen------1) nuclar power plant thermoelectric power plant
2) tidal energy wind enrgy
is pushing a cart with stick contact or non contact force ..experts pl. help me out
why are megathermal power stations located near the coal or oil fields
why should the dry leaves be used to make compost
A player is moving northward suddenly turns westeward with the same speed to avoid an opponent.What type of force that acts on the player and in which direction?
Why don't we use nuclear fusion reaction in nuclear reactor for generating electricity instead of nuclear fission reaction?
what is the definition of renewable resources?
1 Sounds r considered Inaudible on the basis of frequency (Infrasonic Ultrasonic) or Amplitude of the vibrating body?
2. If a sound has a frequency of 100 Hz but loudness of 0 Bel , will it be Audible?
3. WIll the sound also be Audible when the conditions r changed (i.e. Fq.=30 Hz loudness = 100 B)
what is the meaning of stable , unstable and deviation?
Is it necessary that anthracite should have 80%of carbon (C)
Recently, I asked the question that the a good conductor of heat energy is good conductor of electricity. I got the andswer as true. In More about energy chapter it is written under light energy example of magnifying glass and paper. And nuclear energy, chemical energy, solar energy and all other formas of energy are sub-forms of heat energy?As they all release heat energy.
