Answer: 1.22 m
Explanation:
The equation of motion in this situation is:
(1)
Where:
is the final height of the ball
is the initial height of the ball
is the vertical component of the initial velocity (assuming the ball was thrown vertically and there is no horizontal velocity)
is the time at which the ball lands
is the acceleration due gravity
So, with these conditions the equation is rewritten as:
(2)
(3)
Finally:
Miniature circuit breakers is called the developed form of fuse because MCBs are more sensitive to current than fuses. They immediately detect any abnormality and switch off the electrical circuit automatically. This prevents any permanent damage to electrical appliances and human beings
Answer:
Momentum of red car = 5kgm/s
Momentum of blue car = 0kgm/s
Explanation:
Momentum = mass × velocity
For the red car
Mass = 1kg
Velocity = 5m/s
Momentum of the red car = 1kg × 5m/s
Momentum of the red car = 5kgm/s
For the blue car.
Mass = 1kg
Velocity = 0m/s(shows that the blue car is stationery)
Momentum = 1kg ×0m/s
Momentum of the blue car = 0kgm/s
Radioactive isotopes of an atom aren't as stable as you would think, so the correct answer is: C. Less Stable
(I can verify this because I took the test.)
Hope this helps! Have a wonderfully wonderful day!
Cheers mate!
