Answer:
1,355.616Joules
Explanation:
The Amount of energy required is expressed as;
Q = mcΔt
m is the mass of water = 36g
c is the Specific heat of water = 4.184
Δt is the change in temp = 9 degree C
Substitute into the formula
Q = mcΔt
Q = 36(4.184)(9)
Q = 1,355.616Joules
The amount of heat required is 1,355.616Joules
Answer:
7.6427m/s
Explanation:
Given:
#Applying the conservation of momentum along the x-axis:
#And along y-axis:
#Solving for :
#By substitution in the x-axis equation:
Hence the original speed of the ball before impact is 7.6427m/s
Dispersion
Explanation:
The best word that describes the phenomenon that gives rise to rainbow is dispersion of light.
Dispersion is the process by which white light is separated into different colors or radiation according to their different wavelength.
- In the atmosphere, rainbow is an arc of different colors that forms in the sky.
- Rainbow forms when light is dispersed by water in the atmosphere.
- When rainbow forms light is separated into its different colors and it can be seen in the sky.
