Answer:
The average velocity of an object is its total displacement divided by the total time taken. In other words, it is the rate at which an object changes its position from one place to another.
Explanation:
Average velocity is a vector quantity. The SI unit is meters per second. However, any distance unit per any time unit can be used when necessary, such as miles per hour (mph) or kilometer per hour (kmph)
Answer:
Consistency paradox is the observation that a human being’s personality tends to remain the same over time, while their behavior can change in different situations.
Many personality characteristics are relatively constant throughout a person's life, but people can act in all sorts of ways (even ones that seem to be opposite of their personality) in different situations. For instance, even the most even-tempered and easy-going person can be driven to violence when put under enough stress or pressure.
Answer:
T₂ = 1937.68 N
Explanation:
First, we will calculate the weight of the object:
Now, we will calculate the resultant tension in the ropes. Since the ropes are perpendicular. Therefore,
where,
T = Resultant Tension
T₁ = Tension in rope 1
T₂ = Tension in rope 2
According to the given condition tension in the first rope is 2.2 times the tension in the second rope:
T₁ = 2.2 T₂
Therefore
Now, the weight of the object must be equal to the resultant tension for equilibrium:
<u>T₂ = 1937.68 N</u>
