Answer:
7.6427m/s
Explanation:
Given:
#Applying the conservation of momentum along the x-axis:
#And along y-axis:

#Solving for
:

#By substitution in the x-axis equation:

Hence the original speed of the ball before impact is 7.6427m/s
I think it #3(not Sure) I think Its because of their long wavelengths that tsunamis behave as shallow-water waves.
The unit for measuring current is an " ammeter ".
The unit for measuring voltage is a " voltmeter ".
The unit of measure for electrical current is the " Ampere ".
The unit of measure for potential difference (voltage) is the " volt ".
When a balloon is rubbed with a wool cloth, e<span>lectrons move from the atoms in the balloon to the atoms in the cloth, causing the cloth to have a negative charge. Therefore, the answer is B. Before they were rubbed together, they both had balanced charges. However, after rubbing them, the wool is left with the positive charge, and the balloon with the negative. This causes the atoms in the cloth to flow to the balloon, leaving the cloth with a negative charge.</span>
