A stream is 30. meters wide and its current flows southward at 1.5 m/s. A toy boat is launched with a velocity of 2.0 m/s eastward from the west bank of the stream. What is the magnitude (size) of the resultant velocity of the boat on the stream? *
The resultant velocity of the boat on the stream is 2.5 m/s.
What is velocity?
Velocity and speed describe how quickly or slowly an object is moving. We frequently encounter circumstances when we must determine which of two or more moving objects is going faster. If the two are travelling on the same route in the same direction, it is simple to determine which is quicker. It is challenging to identify who is moving the fastest when their motion is in the other direction. The concept of velocity is useful in these circumstances. Learn about the definition of velocity in this article as well as the distinction between speed and velocity.
X = Hor = 2 m/s
Y = Ver = 1.5 vm/s,
tanA = Y/X = 1.5/2 = 0.75,
A = 36.9 Deg.
R = X / cosA = 2/cos36.9 = 2.5 m/s = resultant velocity.
Therefore, resultant velocity = 2.5 m/s

In Edward Tolman’s experiments, the group of rats that ended up with the best results was the one that had __________.
A.
experienced continuous reinforcement
B.
received no reinforcement at all
C.
received reinforcement after eleven days
D.
received reinforcement for the first two days
Answer:
C.
received reinforcement after eleven days
Explanation:
In Edward Tolman’s experiments, the group of rats that ended up with the best results was the one that had received reinforcement after eleven days. Thus, the correct option for this question is C.
What is Edward Tolman’s experiment?Tolman conducted experiments with rats and mazes to examine the role that reinforcement plays in the way that rats learn their way through complex mazes. These experiments eventually led to the theory of latent learning.
In a classic experiment, rats practiced a maze for several days. Then, the familiar path they normally took was blocked. According to the behaviorist view, the rats had simply formed associations about which behaviors were reinforced and which were not.
According to him, behavior implied a performance, the achievement of an altered relationship between the organism and its environment; behavior was functional and pragmatic; behavior involved motivation and cognition; behavior revealed purpose.
Therefore, the correct option for this question is C.

The privileges discussed in the last two paragraphs of the passage best demonstrate that in some instances in the period 1450 to 1750
The era between 1450 and 1750 saw the appearance of several land-based empires who built their power on the use of gunpowder: the Ottomans and the Safavids in Southwest Asia , the Mughals in India , the Ming and Qing in China , and the new Russian Empire.
Internal challenges against the power of the state can result in the establishment of new state-like organizations inside existing states, and that is why the privileges outlined in the last two paragraphs of the text best exemplify it in some cases from 1450 to 1750.
The Tsar's proof of Cossack's requests in the latter two paragraphs shows the development of a client state inside the wider Russian Empire. These cossacks were obligated to do certain tasks, including collecting estate taxes for the tsar, but they were given the authority to manage their affairs on the local level.Learn more:
