No, momentum is conserved so:
momentum before=momentum after
it is C. 100 kg m/s
Answer:
One side is more positive, the other is more negative
Explanation:
When an atom is electrically polarized, it means that one side has more electrons than the other. This makes one side more negative as it has more electrons than the other. I hope this helps!
Answer:
The speed of the water is 14.68 m/s.
Explanation:
Given that,
Time = 30 minutes
Distance = 11.0 m
Pressure = 101.3 kPa
Density of water = 1000 kg/m³
We need to calculate the speed of the water
Using equation of motion
Where, u = speed of water
g = acceleration due to gravity
h = height
Put the value into the formula
Hence, The speed of the water is 14.68 m/s.
Answer: a) 19.21m b) 3.92secs
Explanation:
a) Maximum height reached by the object is the height reached by an object before falling freely under gravity.
Maximum height = U²/2g
U is the initial velocity = 19.6m/s
g is acceleration due to gravity = 10m/s²
Maximum Height = 19.6²/2(10)
H = 19.21m
b) The time elapsed before the stone hits the ground is the time of flight T= 2U/g
T= 2(19.6)/10
T = 39.2/10
Time elapsed is 3.92secs
