Answer:
The correct answer is option a.
Explanation:
Conservation of momentum :
Where :
= masses of object collided
= initial velocity before collision
= final velocity after collision
We have :
Two equal-mass carts roll towards each other.
Initial velocity of
Initial velocity of (opposite direction)
Final velocity of (same direction )
Final velocity of (same direction)
v = 0.5 m/s
rg135
The speed of the carts after their collision is 0.5 m/s.
Answer:
A closed organ pipe is λ/4 (node-antinode) long.
λ = speed / frequency = 331.5 / 259.6 = 1.28 m
λ/4 = .319 m length of closed pipe
An open pipe has a fundamental wavelength of A-N-A or λ/2
The second harmonic would be A-N-A-N-A or λ = 1.28 m for the second harmonic 331.5 / 259.6 = 1.28 (the fundamental would be 331.5 / .628
Answer:
When you blow air into balloon, it expands due to the elasticity of the rubber But after a point, the rubber expanded to its maximum point and
cannot be stretched further If the ballon is blown beyond this point ,it will burst because there will be no space for the rubber to accommodate the air
A person would be driving 4 blocks west from the starting point to make the shorter distance while maintaining same displacement.
<u>Explanation:</u>
The measurement of an object’s position change from its point is called displacement. It is usually calculated from starting to the end points and represented by ‘delta s’. In the given scenarios, the person drove in the way that he finals the driving by 4 blocks away from the west.
Means, the persons drive to 8 blocks north and then to 8 blocks south get cancelled. Hence, to make the shorter distance with maintaining same displacement he would be driving 4 blocks west from the starting point.
