Im. Sorry. Im. Not. Much. Help
Answer:
I think it's B it can not be C or D because it has nothing to do with chemical energy
Answer:
Your answer is B
Explanation:
When a ball falls it is gaining kinetic energy because it gains speed as it falls.Since its gaining kinetic energy it loses potential energy so ur answer is B :) hope it helps
Speed of wave depends mainly on four factors. These factors are wavelength, frequency, medium and temperature.
We know from laws of refraction, when a wave travels from rarer to denser medium, the speed of wave slows down. And when it travels from denser to rarer, it speeds up.
The relation of speed of wave with its wavelength and frequency is given by the following:
The speed of a wave in a particular medium remains constant. A higher frequency wave has shorter wavelength.
The speed of a wave also varies with temperature in a given medium. temperature affects the density of the medium and vibrations of the medium particles. Higher the temperature, higher is the speed of wave.
The factors that affect the speed of a wave are wavelength and medium. The correct option is B.
Wavelength and the characteristics of the medium a wave travels through are the two key parameters that affect a wave's speed.
Wavelength is the separation between successive wavepoints, and medium is the substance or material through which the wave is travelling, such as air, water, or solids.
The speed of the wave typically decreases as the wavelength rises. Additionally, the densities, compositions, and properties of various media can vary, which has an impact on how quickly a wave can go through them.
For instance, sound waves move through the air more quickly than they do through water. In disciplines like physics, acoustics, and communications, having an understanding of these elements is essential.
Thus, the correct option is B.

The net force of an object moving with constant speed in a circular motion is in tangential direction​.
Uniform circular motion is a type of motion of a particle around a circle at a constant speed. The magnitude of the speed of the particle is constant.While the direction is changing continuously.
Kinetic energy, acceleration, and displacement of the following is constant for an object in uniform circular motion.
Hence,the net force of an object moving with constant speed in a circular motion is in tangential direction​.

Answer:
The law of conservation of energy applies to eating your favorite food in that the energy contained in the food is being converted to energy usable for the body system after the final digestion(Glucose or simple sugar, amino acid, etc)
Examples of transformation of energy include
(1) Transformation from Chemical energy in battery to light energy in bulb
(2) Transformation of Electrical energy to thermal/Heat energy in electric stove.
Explanation:
The law of conservation of energy states that energy can neither be created or distroy. It can only by converted from one form to another.
