Try liters if you haven’t done it yet. I’m so sorry if i’m incorrect.
Answer:
Final velocity of both goalie & puck = 0.018116 m/s
Explanation:
M1U1 + M2U2 = (M1+M2)V
70 x 0 + 0.17 x 33.5 = (70+0.17)V
V = 0.08116m/s
Answer:
Max kinetic energy for 340 nm wavelength will be 
Explanation:
In first case wavelength of electromagnetic radiation 
Plank's constant 
Maximum kinetic energy = 0.54 eV
Energy is given by 
We know that energy is given
, here
is work function
So 

Now wavelength of second radiation = 340 nm
So energy 
So 
The disturbance does not have a specific motions
<span>Hey there!
Awesome question=)
Siobhan can place it on a regular scale(0 gravity area), or she can use the "balance scale"
</span>
I hope this helps;)
