Answer:
68.5 meters
Explanation:
Given:
v₀ = 0 m/s
a = 9.8 m/s²
t = 3.74 s
Find: Δy
Δy = v₀ t + ½ at²
Δy = (0) (3.74) + ½ (9.8) (3.74)²
Δy = 68.5
The egg fell 68.5 meters.

sorry if it wrong g
To solve this exercise we will use the expression of the displacement in the aromatic movement in the two given points. Thus we will find the value of time as a function of frequency. In the end we will replace that value and find the time taken,
The expression for the displacement of the object in simple harmonic motion is
At the initial position the value of x is zero,
Now the expression for the displacement of the object in simple harmonic motion is
At the final position the value of x is -1.8cm
Replacing we have that
The total change in time will be
Replacing the value of the frequency we have that
Therefore the time taken for the displacement in the interval of x=0 to x=-1.8 is 0.05s
Answer:
Electric field, E = 45833.33 N/C
Explanation:
Given that,
Separation between the plates, d = 4.8 mm = 0.0048 m
The potential difference between the plates, V = 220 volts
We need to find the electric field between two parallel plates. The relation between the electric field and electric potential is given by :
E = 45833.33 N/C
So, the electric field between two parallel plates is 45833.33 N/C. Hence, this is the required solution.
