The time interval in which your friend beats you is determined as 4.2 minutes.
<h3>Time in which you catch up with your friend</h3>
The time interval in which your friend beats you is determined from the principle of relative velocity.
(Va - Vb)t + (Vc - Vd) = d
(6 - 3)t - (6 - 9)t = 1500
6t = 1500
t = 1500/6
t = 250 s
Time in minutes = 250 s/ (60s/min) = 4.2 minutes
Thus, the time interval in which your friend beats you is determined as 4.2 minutes.

(B) 1.00 m
Explanation:
Since the meter stick is traveling with Jill, it will have the same speed as she does so relative to Jill, the meter stick is stationary so its length remains 1.00 m as measured by her.
That would be a series circuit

a) , b) , c) , d)
Explanation:
a) The friction force is:
The work done by friction is:
b) The work done by gravity is:
c) As normal force has a direction perpendicular to motion direction, the work done is equal to zero:
d) The net work done on the package is:
On top of this, HIV can even kill uninfected immune system cells, a phenomenon we are just beginning to understand. This is why HIV is named the “human immunodeficiency virus”. When the immune system is damaged, it is treacherously difficult for your body to fight against HIV or other opportunistic infections.
