Answer:
A trough
Explanation:
A trough is an elongated area of relatively low pressure extending from the center of a region of low pressure.
I HoPe ThIs Helps!!!
∆v = -5 m/s
∆t = 5 s
a = ∆v/∆t = (-5 m/s)/(5 s) = -1 m/s^2 .
I know that's the right answer.
I THINK that's what choice-B is trying to say.
<h3>What is the fullform of SMPS ?</h3>

Answer:
The track's angular velocity is W2 = 4.15 in rpm
Explanation:
Momentum angular can be find
I = m*r^2
P = I*W
So to use the conservation
P1 + P2 = 0
I1*W1 + I2*W2 = 0
Solve to w2 to find the angular velocity
0.240kg*0.30m^2*0.79m/s=-1kg*0.30m^2*W2
W2 = 0.435 rad/s
W2 = 4.15 rpm
