To make a small scale whirlpool of water, take a cup and fill it with water and stir. It will create a vortex that pulls particles down.
Or you could see this when draining a tub of water.
Answer: actually to solve this u must know what 3.2m/s2 is..do u know it ??...wel let me tell...3.2m/s2 means that in every second the speed of the body increases by 3.2m/s..so if it acts for 6.8 seconds..increase in speed will be 3.2*6.8 however note that this is the increase in speed.. have to change this in km/hr & add this to the initial speed(27km/hr) to get the answer....hope this has cleared ur doubts....
Explanation:
Answer:
9800 N
Explanation:
applying,
W = Fd.................. Equation 1
Where W = work done by the engine, F = Force exterted to lift the beam, d = distance.
make F the subject of the equation
F = W/d............... Equation 2
From the question,
Given: W = 1421000 J, d = 145 meters.
Substitute these values into equation 2
F = 1421000/145
F = 9800 N

Answer:
Initial velocity of the bullet will be 307.63 m /sec
Explanation:
We have given that mass of the bullet 7.87 gram m= 0.00787 kg
Mass of the block M = 4.648 kg
So total mass M+m = 4.648 +0.00787= 4.655 kg
Spring constant k = 142.7
Compression x=9.46 cm = 0.0946 m
Now according to energy conservation
So initial velocity of the bullet will be 307.63 m /sec
