Answer: According to http://www.scifun.org, "Bernoulli's Principle says that the pressure decreases inside a stream of flowing air. When the balloon begins to move out of this low pressure stream, the higher pressure of the air in the room pushes it back into the moving stream"
The amplitude of a wave is a measure of the energy it carries. The amplitude of a wave is the distance between the midline of a wave and its crest or trough.
Amplitude measures the amount of energy being transported by a wave. The larger the amplitude, the more the energy that a wave has.
Wave such as water waves have energy. Smaller waves have less energy because they have a smaller amplitude. Tsunamis have very high amplitudes and thus have a huge amount of energy
The correct answer is D. Atoms of the same element can have different number of neutrons.
Answer:
3.61 m
Explanation:
First, find how long it takes to land.
Given (in the y direction):
Δy = 16 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
(16 m) = (0 m/s) t + ½ (9.8 m/s²) t²
t = 1.81 s
Given (in the x direction):
v₀ = 2.0 m/s
a = 0 m/s²
t = 1.81 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (2.0 m/s) (1.81 s) + ½ (0 m/s²) (1.81 s)²
Δx = 3.61 m
Answer:
1 m/s²
Explanation:
a = v² / r
a = ω² r
a = (2π rad / 2π s)² (1 m)
a = 1 m/s²
