Answer:
Explanation:
The equation of the position is:
Where:
v(i) is the initial velocity
The initial position y(i) will be zero and the final position y = 3.60 m.
So, we just need to solve this equation for v(i).
Therefore, the initial velocity is 10.10 m/s upwards.
I hope it helps you!
Answer:
Option 4
Explanation:
During heating actually heat transfer takes place from a body at higher temperature to a body at lower temperature and the heat transfer takes place until both attain the same temperature
Therefore heat transfer depends on the temperature of the systems
Now while comparing the thermal energies of the systems, if both the systems have same mass then the system which is at higher temperature has greater thermal energy when compared to the system which is at lower temperature
So in this case assuming that both the systems have same mass then the energy will leave the system with greater thermal energy and go into the system with less thermal energy as the system with greater thermal energy in this case will be at higher temperature and we are considering this assumption because thermal energy not only depends on temperature but also depends on mass of the system
Answer:
Correct answer is ''c'' Art for art's Sake
Explanation:
Wilde wrote in the literary movement called Aestheticism during the late nineteenth century. Contrary to popular belief, Wilde did not create the literary movement, but played a role as a leader who promoted the movement. While Wilde was a college student the works of Algernon Charles Swinburne and Edgar Allan Poe influenced his own writing style. Also, the English essayist Walter Pater helped to form Wilde's humanistic aesthetics.
The philosophical foundations of Aestheticism come from Immanuel Kant. He formulated the idea of "art for art's sake". He believed that art was to be enjoyed for its own beauty regardless of social or moral concerns.

Answer:
The object´s displacement vector is Δr = 8i - 6 j
Explanation:
Hi there!
The position vector is given by the following function:
r = t²i - (3t + 3) j
Let´s find the position of the object at time t1 and t2:
At t1 = 1 s:
r1 = (1)² i - (3 · (1) + 3 )j
r1 = 1 i - 6 j
At t2 = 3 s:
r2 = (3)² i - (3 · (3) + 3) j
r2 = 9 i - 12 j
The displacement is calculated as follows:
displacement = Δr = final position - initial position = r2 - r1
r2 - r1 = 9 i - 12 j - (1 i - 6 j)
r2 - r1 = 9 i - 12 j - 1 i + 6 j
r2 - r1 = 8 i - 6 j
The object´s displacement vector is Δr = 8i - 6 j
