Answer:
Diffraction
Explanation:
The bending of light around obstacle called diffraction.
Answer:
v = 2.45 m/s
Explanation:
first we find the time taken during this motion by considering the vertical motion only and applying second equation of motion:
h = Vi t + (1/2)gt²
where,
h = height of cliff = 15 m
Vi = Initial Vertical Velocity = 0 m/s
t = time taken = ?
g = 9.8 m/s²
Therefore,
15 m = (0 m/s) t + (1/2)(9.8 m/s²)t²
t² = (15 m)/(4.9 m/s²)
t = √3.06 s²
t = 1.75 s
Now, we consider the horizontal motion. Since, we neglect air friction effects. Therefore, the horizontal motion has uniform velocity. Therefore,
s = vt
where,
s = horizontal distance covered = 4.3 m
v = original horizontal velocity = ?
Therefore,
4.3 m = v(1.75 s)
v = 4.3 m/1.75 s
<u>v = 2.45 m/s</u>
Answer: 0.00000938422m^3
Explanation:
dV=Vø*β*(t1-tø)
The parameters are
dV is the change in volume after temperature increase
Vø =0.607 *10^-3m3 is the initial vokume of coffe at 16.2^0 C
β= coefficient of volume expansion of water at 16.2^0 C is 0.0002/0C
t1= 93.5^0C final temperature
tø=16.2^0 C
Therefore
dV=0.607 *10^-3 *0.0002*(93.5-16.2)
dV= 0.00000938422m^3
This is the volume of coffee that will spill over the container
