Chemical change, we can't change the bread back the way it was before
Hope this helps!
Answer: Acceleration is directly proportional to force.
Explanation: According to Newton's Second Law of Motion the amount of Force is equal to the product of mass and acceleration or F = ma. If we derive this formula for acceleration it will become a = F / m.
The relationship between acceleration and force is directly proportional which means that greater force will result to greater acceleration as along mass remains constant.
Speed = distance / time
= 125 miles / 2 hr
= 62.5 mi/h
Convert 65.5 mi/h to km/h
= 65.5 / 5
= 13.1
=13.1 x 8
= 104.8 km/h
Therefore speed equal 104.8 km/h
Answer: has wavelengths that are longer than visible light
Explanation: Electromagnetic spectra comprises of different electromagnetic waves which are arranged in order of increasing wavelengths or decreasing energies.
In order from highest to lowest energy, the waves are arranged as: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.
E= energy
h= planck's constant
c= velocity of light
= wavelength
As wavelength and energy are inversely related, the wave having higher wavelengths will be lowest in energy. Thus as infrared radiation have lower energy as compared to visible radiation. Thus infrared radiation have higher wavelength as compared to visible radiation.
Answer:
Ernest Rutherford observed that particles with a positive charge deflected when passing through a thin sheet of gold foil, concluding that the atom's positive part is small and dense.
Explanation:
The Ernest Rutherford experiment describes planetary model of an atom. According to the model, an atom has a tiny, compact, positively charged centre called a nucleus, where almost all of the mass is concentrated, while light, negatively charged particles called electrons orbit far around it, much like planets orbit the Sun. In his experiment, the observation that a positive charge is deflected through a thin sheet of gold foil led to the conclusion that the deflection some of the positive charge occurs in a small region of the atom. At the same time, the majority passed through the atom (which was also concluded to be empty space).
