(9.39 x 10⁹ sec) x (1 day / 8.64 x 10⁴ sec)
= (9.39 / 8.64) x 10⁵ days
= 108,680.56 days
Answer:
Explanation:
The amount of gas, the volume, and the temperature.
Answer:
0.78m (rounded to nearest hundredth of a meter)
explanation:
time taken for going up=time taken for drop down after reaching the highest point. at the highest point, the velocity becomes 0.
now all thats left is dropping an object from a height (h) and seeing how long it takes to reach the ground. then find out the flight’s total time divided by 2 (0.8/2=0.4)
lets say the velocity is v and the height she jumped to is h. we can make a kinematic expression:
s=vt+½gt²
once we put it all together you should get this:
h=0×0.4+½(9.81) 0.4²
.
∴
Time taken for downward drop

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 
i will b i don't now but you said you was suffering so i have to help you i'm going to put a thank you on you name okay bye
