Answer:
The momentum would be doubled
Explanation:
The magnitude of the momentum of the freight train is given by:
where
m is the mass of the train
v is its speed
In this problem, we have that the speed of the train is unchanged, while the mass of the train is doubled:
therefore, the new momentum is
so, the momentum has also doubled.
Answer:true,because velocity is directly proportional to speed or velocity
Explanation:
Velocity = frequency x wavelength
The velocity or speed varies directly with the frequency, so as the frequency is increased, the velocity or speed is also increased
Answer:
conduction.
Explanation:
Hoped I helped! Im Eve btw have a great day and consider marking this brainliest if you do thank you in advanced!
I think its <u>B</u> because it looks like it might indicate a future rain storm.
