Answer: C
Period and wavelength
Explanation:
Mechanical wave requires a medium for it propagation transfering energy through a medium. The waves can move over long distances but limited due to the movement of the medium of the material causing the oscillating material not move far. This depends on the period and the wavelength of the wave.
Answer:
In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.
Explanation:
When a solid is heated, the particles are given more energy and start to vibrate faster. ... The temperature at which this change from solid to liquid happens is called the melting point. Each solid has a set melting point at normal air pressure. At lower air pressure, such as up a mountain, the melting point lowers.
Answer:
A. 400 J
Explanation:
Because the process is isochoric, no volume change, so no work, so none of the energy is lost or converted. In other words, the system will gain and hold onto all of the J of heat put into it, which was 400J
Answer:
In bringing you to a halt, the sand and the water exert the same impulse on you, but the sand exerts a greater average force
