formula for wavelength = speed/frequency
So 1500/200 = 7.5 meters
In my opinion it does. The more water the pot holds, the longer you need to wait for it to freeze. Since there is more water, some parts may not be completely frozen. An experiment you can try is to get an ice cube container and a pot. fill both of them and put them in the freezer for the same amount of time. When you take it out, the ice cubes should be frozen leaving the pot with cold water.
Answer:
One method to solve this problem is to take the ball and the floor as the system
second method to solve this exercise and we take the system as formed by the ball only
Explanation:
One method to solve this problem is to take the ball and the floor as the system, therefore the forces that occur during the collision are driving force and reaction, internal to the system, therefore the moment is conserved.
A second method to solve this exercise and we take the system as formed by the ball only, in this case there is a change at the moment and this is not preserved, This second case is a little more difficult to solve
The ideal mechanical advantage of a lever (IMA) is given by:
Where:
Le = Effort of the arm
Lr = Resistance arm.
Therefore, we can increase the force adventage by increasing the effort arm or reducing the load arm
Answer:
a. Make the effort length longer.
