they are eukaryotes that have cell walls, are heterotrophs that feed by absorbing their food, and use spores to reproduce.
Answer:
The speed of the animals is 1.64m/s.
Explanation:
Let us work with variables and call the mass of the two rats and , and the length of the rod .
Using the law of conservation of energy, which says the potential energies of the rats must equal their kinetic energies, we know that when the rod swings to the vertical position,
,
solving for , we get:
Putting in the values for , , , and we get:
Therefore, as the rod swings through the vertical position , the speed of the rats is 1.64 m/s.
Answer:
v₁ = 3.5 m/s
v₂ = 6.4 m/s
Explanation:
We have the following data:
m₁ = mass of trailing car = 400 kg
m₂ = mass of leading car = 400 kg
u₁ = initial speed of trailing car = 6.4 m/s
u₂ = initial speed of leading car = 3.5 m/s
v₁ = final speed of trailing car = ?
v₂ = final speed of leading car = ?
The final speed of the leading car is given by the following formula:
<u>v₂ = 6.4 m/s</u>
The final speed of the leading car is given by the following formula:
<u>v₁ = 3.5 m/s</u>
Answer: I looked it up and it says something about the waves traveling in a solid but I don’t know if that’s correct.
