Answer:
3. Is 180◦ out of phase with the original wave at the end.
Explanation:
Here when wave is reflected by the rigid boundary then due to the rigidly bounded particles at the end or boundary they have tendency not to move and remains fixed at their position.
Due to this fixed position we can say when wave reach at that end the particles will not move and they apply equal and opposite force at the particles of string
Due to this the reflected wave is transferred back into the string in opposite phase with respect to the initial wave
so here correct answer will be
3. Is 180◦ out of phase with the original wave at the end.
The reason as to why the substage condenser does not need to be included in computing the magnification and the only component needed is the ocular lens and the objective lenses is because the condenser is only responsible for gathering light and it does not contribute with the magnification of the object under the microscope.
I would say Technological Monopolies. Access to large markets might have not been so important back then, but it is definitely needed for consumers now. Transportation was also something not so critical but now it is one of the biggest fraction of government spending. Proximity to sources of energy are needed both by the people during the IR and people today to maintain the success the IR brought us. A well-trained workforce is also needed in both circumstances, as people without training can mess up factors of production and damage reputation.
net force = applied force + gravity = 18N+(1.5kg)(-9.8m/s^2) = 3.3N
Force=mass times acceleration
acceleration=Force/mass
acceleration=3.3/1.5 m/s^2
acceleration=2.2m/s^s
The distance you should cover is: S=150 km
Your average speed is: v=50 km/h
Therefore, to calculate the time you will take to cover this distance, we can use the basic relationship between space, distance and time, and we find:
so, you will take 3 hours.
