Answer:
2.52 ml/s
Explanation:
Unit conversions:
1 mm = 0.001m
70 cm = 0.7 m
Let g = 10m/s2. If the pistol is fired horizontally at first, it did not have an vertical velocity, only horizontal velocity. So g is the only thing that affects the vertical motion of water.
We can calculate the time it takes for the squirts to hit the ground in the following equation of motion:
where h = 0.7 m is the vertical distance, and t is the time it takes, which is what we are solving for:
So the squirts takes 0.374s to hit the ground, and within that time it travels a distance of 1.m horizontally. Neglect air resistance, we can calculate the horizontal velocity:
where s = 1.2 m is the horizontal distance
The cross-section area of the hole is
where r = d/2 = 0.001/2 = 0.0005 m is the radius of the hole
So we can calculate the volume flow rate:
or 2.52 ml/s
Answer:
Distance covered by Neva = 300 m
Displacement of Neva = 0 m
Explanation:
Given:
Length of the pool = 50 meter
Number of laps Neva swam = 3
1 lap is to swim to the other side and back.
To find the distance and displacement.
Solution:
To calculate the distance swum by Neva we will find the total length covered by Neva in 3 laps.
1 lap is 50 meters to the other side and 50 meters back
So, the length of 1 lap =
Total length of 3 laps =
To calculate the displacement we will find the distance between initial position and final position.
We, see that on completing 3 laps Neva returns to her starting point. Thus the initial and final position are the same. Do, the distance between initial position and final position will be = 0 m
Distance covered by Neva = 300 m
Displacement of Neva = 0 m

When a body moves in a simple harmonic motion, its acceleration at the end of its path is more than that of the acceleration at equilibrium.
The acceleration of the body moving in Simple Harmonic Motion(SHM) is given by,
Acceleration = ω^2 A
Here w is the angular velocity of the body and A is the amplitude.
A is the maximum distance of the body from the equilibrium position.
When the body is at an equilibrium position, its amplitude is equal to zero.
Hence, acceleration = ω^2 x 0 = 0
When the body is at the end of its path, its amplitude is equal to A.
Hence, acceleration = ω^2 x A
Therefore,
when a body moves in a simple harmonic motion, its acceleration at the end of its path is more than that of the acceleration at equilibrium.
