Answer:
4.5 metres
Explanation:
Using Hooke's Law (
)
We need to find the spring constant of the bungee cord with the given extension and force, we can do this by substituting in known values.
Now we have found the spring constant of the bungee cord, we can substitute it in for the a different force. As the cord is the same we can use the same spring constant.
Answer:
while using brainly app. there is an option of uploading image of diagram, graph or plot. plz use that feature to upload image of the standing wave so that your question can be properly answeres

Answer:
300kgm/s
Explanation:
Given parameters:
Mass of TV = 30kg
Height of building = 5m
Maximum speed = 10m/s
Unknown:
Momentum before it hits the ground = ?
Solution:
Momentum is the quantity of motion a body possess or contains. It is expressed as;
Momentum = mass x velocity
Insert the parameters and solve;
Momentum = 30 x 10
Momentum = 300kgm/s
