Answer:
Option (C)
Explanation:
Recreational drugs are usually referred to those drugs or medicines that are legally or illegally used without any prescription given by the doctors. These drugs include marijuana, cocaine, alcohol, nicotine, heroin, and many others. These drugs provide relaxation for a shorter period of time, but using of these substances, it makes an individual addicted to drugs.
So, recreational drugs are one of the most potentially destructive ways to handle stress when a student is in college.
Thus, the correct answer is option (C).
Initial velocity = 25 m/s, angle 60°
sin (60°) = opposed leg / hypothenuse = Vertical velocity / Initial velocity
=> Vertical velocity = initial velocity * sin (60°) = 25 m / s * 0.866 = 21.65 m/s
Answer:
a)T= mg/2
b) T = 31. 88 N
c)Tension will increase
Explanation:
Given that m= 6.5 Kg
a)
The force due to gravity = m g
The tension in the chain = T
The total tension = 2 T
By balancing force in vertical direction
2 T = m g
T= mg/2
b)
2 T = m g
2 x T = 6.5 x 9.81
T = 31. 88 N
c)
Lets take angle made by chain is θ
So the total tension in vertical direction = 2 T cos θ
2 T cos θ = m g
T= mg/(2cos θ)
It means that tension will increase because cos θ is always less than 1.
