Answer:
0.14 J
Explanation:
The maximum velocity is the amplitude times the angular frequency.
vmax = Aω
ω = vmax / A
ω = (3.2 m/s) / (0.06 m)
ω = 53.3 rad/s
For a spring-mass system:
ω = √(k / m)
ω² = k / m
k = ω²m
k = (53.3 rad/s)² (0.050 kg)
k = 142 N/m
The elastic potential energy is:
EE = ½ kx²
EE = ½ (142 N/m) (0.044 m)²
EE = 0.14 J
Answer:
A mousetrap makes use of a simple machine called a lever.
Explanation:
In a second-class lever the effort force is at the other end, with the load in the middle. In a third-class lever, the load is at the end and the effort force is between the fulcrum and the load. When you set the mousetrap, you are using a second-class lever. Sorry if I get this wrong. I am in 5th grade! ♥
Explanation:
Waves are disturbances that transmits energy from one point to another either using the particles of the medium or not.
There are different forms of waves.
The electromagnetic waves is produced by the sun and it transmits energy to all the universe
Ocean waves are clearly physical and we can see how they propagate in nature.
Causes of waves:
- The ultimate cause of a wave is a source of disturbance and energy.
- In the ocean, wave are caused by winds when they cause friction over surface waters.
- Electromagnetic waves are energetic waves that transmits their own energy outward.
- Temperature differences between places can cause waves too.
- Vibration can lead to generation of waves.
- Pressure differences
