The answer is “increasing wavelength near beach”
Answer:
Electrostatic field is a conservative field. That is work done when a charge is moved between two points is independent of path taken. Hence answer is W1
(+105) + (+80) = 185 units.
The resultant amplitude of the wave is 185 units.
Answer: A
Explanation: mass and friction are proportional if the mass increases the friction increases
Answer:
The smaller ball (the tennis ball) will receive a much larger acceleration than the soccer ball of larger mass.
According to Newton's 2nd Law of motion, (force equals mass times the acceleration imparted)
Since in this case we have the same force (50 N) applied to two different masses (one the tennis ball "m" which has smaller mass than the soccer ball of mass "M"), then the resultant accelerations will be different being the acceleration of the tennis ball () much larger than the acceleration imparted to the soccer ball (), as can be seen from solving for the acceleration in the previous equation:
