Answer:
The pressure in the chamber are of p= 0.127 atm.
Explanation:
n= 2.5 moles
T= 310 K
V= 0.5 m³ = 500 L
R= 0.08205746 atm. L /mol . K
p= n*R*T/V
p= 0.127 atm
Answer:u=-22 m/s
Explanation:
Given
mass of puck 
Average force 
time of contact 
puck leaves with a velocity of 
We know impulse is 

therefore



Final momentum 


Impulse on the ball 
Impulse
Initial velocity is given by

i.e. initially ball is moving towards -x-axis
I think it’s 150 because if u multiply 3 x 50 it’s 150 but so it’s ore simple you do 3 x5 equals 15 then add the zero from the 50 so you’ll get 150 hope I helped
Answer:
True
Explanation:
A different type of habitat exists in the caves. There exist no green plants/producers but still various life forms evolve with in the caves. The major source of nutrients with in the caves is water and intrusion of other organism that led to deposition of food in the form of debris/guano etc. These food deposits are intake by the organisms living in caves leading to start of food cycle. This is very much similar to any other food cycle
Answer:
Explanation:
1.) What is the net force in the horizontal (x) direction?
Fnet = 8 - 3 = 5 N left
2.) what is the acceleration in the horizontal (x) direction?
a = Fnet/m = 5/2 = 2.5 m/s² left
