Answer:
Speed of larger piece is 
Explanation:
We apply the principle of conservation of momentum.
The watermelon is initially at rest. The initial momentum = 0 kg m/s in all directions.
After the collision,
Vertical momentum = momentum of piece in y-direction + y-component of momentum of larger piece = 
Here, 
is the y-component of velocity of larger piece.
This is equal to 0, since the initial momentum is 0.
Horizontal momentum = momentum of piece in x-direction + x-component of momentum of larger piece = 
Here, 
is the x-component of velocity of larger piece.
This is also equal to 0, since the initial momentum is 0.
The velocity of the larger piece, 
, is the resultant of and . Since they are mutually perpendicular,
Na + Cl
An ionic bond is made between a metal and a non-metal
The amplitude of the wave is the 'full height of the wave.' Amplitude is measured in m (meters) and is measured over the change of a single period.
I think shock waves require more speed they travel at the speed of sound
Answer:
0.2 T
Explanation:
Magnetic field is inversely proportional to the distance from wire since the distance is halved therefore magnetic field will be doubled.
