The highest tides are on full moons
Answer:
v2=0.79 m/s
Explanation:
equation of continuity: V1A1=V2A2
A=(pi)r^2
A1=(pi)(0.55cm)^2
A2=(pi)(1.17cm)^2
convert cm2->m2
A1= 0.95cm2=
A2= 4.3cm2=
(3.57 m/s)(0.000095 m^2)=(x m/s)(0.00043 m^2)
v2=0.79 m/s
hope this helped
Answer:
Whenever you see the delta symbol infront of another, it always represents change. In other words:
Δu = u_f - u_i
- u_i means "initial velocity"
- u_f means "final velocity"
And in general, ΔX means Xfinal - Xinitial
Answer:
The height from which the egg is dropped is <u>68.54 m</u>.
Explanation:
Given:
Initial velocity of egg is,
(Dropped means initial velocity is 0)
Time taken is,
Acceleration experienced by egg is due to gravity,
The height from which the egg is dropped is, 
Now, we use Newton's equation of motion that relates the distance, initial velocity, time and acceleration.
So, we have the following equation of motion:

Plug in all the given values and solve for 'd'. This gives,

Therefore, the height from which the egg is dropped is 68.54 m.
