Answer:
Accelrtation:a vehicle's capacity to gain speed within a short time.EX:An object was moving north at 10 meters per second.
Velociy:the speed of something in a given direction EX:Velocity is the rate of motion, speed or action. An example of velocity is a car driving at 75 miles per hour.
Explanation:
Albedo is how much sunlight reflects off the surface of the Earth. More albedo could mean a number of things. Higher temps, more photochemical smog, it all depends on where the albedo is occurring.
Let there be light! At the flick of a switch, a light bulb can light or illuminate an entire room, but what else is happening? One the basic laws of physics, the conservation of energy, tells us that energy is neither created nor destroyed: rather, it can only be transformed from one form to another. In the case of the light bulb, electrical energy is being transformed into light and thermal (heat) energy. Different wattages and types of bulbs give off varying amounts of light and heat. In this light bulb science project, we'll be working with incandescent and compact fluorescent lamp bulbs (CFL’s).
Answer:
Rmax = 3.4 10⁶ m
Explanation:
For this exercise we will use the concept of energy
Initial. On the surface of the luma
Em₀ = K + U
Em₀ = ½ m v² - G m M / R_moon
Final. At the furthest point
Emf = U
Emf = - g m M / R_max
Em₀ = Emf
½ m v² - G m M / R_moon = - G m M / R_max
½ v² + G M (-1 / R_moon + 1 / R_max) = 0 (1)
Let's use the fact that tells us that the speed of the rocket is equal to the speed of a satellite that rotates around the moon near the surface, let's use Newton's second law
F = m a
Acceleration is centripetal
a = v² / r
r= R_moon
G m M / R_moon² = m v² / R_mon
G M / R_moon = v²
We substitute in 1
½ G M / R_moon + G M (1 / R_max - 1 / R_moon) = 0
1 / R_max = 1 / R_moon (1- ½)
R_max = R_moon 2
Rmax = 2 1700 103
Rmax = 3.4 10⁶ m
Loud sound waves have greater __________ and carry more energy than soft ones. *
