The current in a river is 1.0 meters/second. Britney swims 300 meters against the current. If she normally swims with a speed of 2.0 meters/second in still water, how long does it take her to complete the trip?
2 answers:
Answer:
t = 300 seconds
Explanation:
It is given that,
Speed of the current in the river,
Distance covered by Britney, d = 300 m
Speed of Britney,
It is mentioned that Britney swims against the current. Her downstream speed is given by :
v = 1 m/s
Let t is the time taken by her to complete her trip. t is given by :
t = 300 seconds
So, the time taken by her the complete her trip is 300 seconds. Hence, this is the required solution.
The answer is 300s I believe.

Answer:
B) 300 J/°C
Explanation:
Q = 3kJ = 3000J
ΔT = 10°C
3000J/10°C = 300J/°C
Hey, I think someone should help u cause I’m stuck too Hope this helps !
Explanation:
I want to say option B - Both forces can act without objects touching.
You can use the impulse momentum theorem and just subtract the two momenta. P1 - P2 = (16-1.2)(11.5e4)=1702000Ns If you first worked out the force and integrated it over time the result is the same
This is something u are going to have to do
