Explanation:
We have,
Mass of a baseball is 0.147 kg
Initial velocity of the baseball is 44.5 m/s
The ball is moved in the opposite direction with a velocity of 55.5 m/s
It is required to find the magnitude of the change in momentum of the ball and of the impulse applied to it by the bat.
Change in momentum,
Impulse = 14.7 kg-m/s
Therefore, the magnitude of the change in momentum of the ball and of the impulse applied to it by the bat is 14.7 kg-m/s
A) Up is the direction of the magnetic field at point Z.
the independent variable is what you're testing or changing in an experiment, so the answer is the temperature of the ball when its dropped.
i hope that helped <3
Answer:
The second is correct.
Explanation:
Try with a magnet and experiment. You'll find out
Hi!
I believe that there were the following options in this question:
<span>A) Which color bends the most to make a rainbow?
B) What color of scented marker has the best smell?
C) Which flower has the prettiest shade of purple on its petals?
D) What is the best-looking color on a high-performance sports car</span>
Now, options b), c) and d) are about a personal preference and opinion - they are not scientific uqestions.
The correct answer is a) - it asks about the properties of light.
