Energy that comes from moving objects or objects that have stored energy is called Motion Energy
A prism is a piece of glass or plastic in the shape of a triangle. A prism works because the different colors of light travel at different speeds inside the glass. Because the colors of light travel at different speeds, they get bent by different amounts and come out all spread out instead of mixed up.
Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. Refraction is responsible for image formation by lenses and the eye.
Answer: Wernicke's aphasia
Explanation:
John recently suffered a blow to his head. Since then, he finds it difficult to comprehend what others say to him. He also finds it difficult to express his thoughts and cannot seem to find the right words to say while speaking. However, he can speak freely with proper syntax. In this scenario, John is most likely suffering from Wernicke's aphasia.
Wernicke's aphasia occurs when the leftward side of the middle of the brain is damaged or has been altered. An individual who suffers from Wernicke's aphasia will have difficulty in speaking in meaningful and coherent sentences or may have difficulty in understanding the speech of others.
Answer:
Acceleration of the particle is 4.45 m/s² and acceleration direction is towards the 8 kg point mass.
Explanation:
Let m₁ be 8 kg point mass and m₂ be 12 kg point mass and take direction along m₁ mass as positive x-axis. The separation between twp point masses is 50 cm. According to the problem, a particle of mass m is held between the two point masses m₁ and m₂.
Distance between m₁ and m, r₁ = 20 cm = 0.2 m
Distance between m₂ and m, r₂ = (50 - 20) cm =30 cm = 0.3 m
The particle of mass m experiences an attractive gravitational force due to both the point masses. Thus, the net force on the particle of mass m is :
F = F₁ + F₂
F₁ is acting along the positive x axis and F₂ is acting along the negative x axis.
Substitute the values of G, m₁, m₂, r₁ and r₂ in the above equation.
F = 4.45m N/kg
Acceleration of the particle = 
= 4.45 m/s²
The direction of acceleration of the particle is towards the 8 kg point mass.
