olchik [2.2K]

Answer:

a.neither of them is correct

b. Zach's statement is not correct, since do not know where the objects started and can't be sure if they pass each other.

c. Victoria's statement is not correct as the objects have the opposite accelerations, however free-falling objects should have the same downward acceleration

Explanation:

Fiqure 1) shows the velocity-versus-time graphs for two objects A and B the motion of the ohiecds Zach savs The aranh could represent two cars Zach traveling in opposite directions that pass each other."

Why is Zach's statement wrong? Check all that apply

. A Zach's statement is not correct, since the objects move in the same direction for some time interval.

Ans: Zach's statement is not correct, since do not know where the objects started and can't be sure if they pass each other.

Part C

Why is Victoria's statement wrong? Check all that apply Victoria's statement is not correct as the objects both should have been thrown either upward or downward

Answer:. Victoria's statement is not correct as the objects have the opposite accelerations, however free-falling objects should have the same downward acceleration gGraph

My explanation further from the graph will be that there are opposite bodies, one is accelerating with time , why the other is decelerating with time.

Lilit [14]

Answer:

a) \vec{d} =B-A

b) I=\frac{B*v*d*\sin 90 \textdegree}{R}

c) v \approx 0.6m/s

Explanation:

From the question we are told that

Magnetic field strength B=3.6T

Distance traveled d=7m

Mass m=4.7 kg

Resistance r=8.2 ohm

Gravitational acceleration g=9.8m/s^2

\theta =90 \textdegree Because of perpendicularity

a)

Generally the direction of the current will be given as

\vec{d} =B-A

Because it opposes increases of magnetic flux

b)

Generally the equation for induced EMF E is mathematically given as

E=B*v*d*\sin \theta

E=B*v*d*\sin 90 \textdegree

Generally the equation for induced current I is mathematically given as

I=E/R

I=\frac{B*v*d*\sin 90 \textdegree}{R}

c)

Generally the the equation for force F at terminal speed is mathematically given as

F=mg

mg=B*I*d*\sin 90 \textdegree

mg=B*(\frac{B * v * d }{R}) *d

v=\frac{m*g*R}{B^2*D^2}

v=\frac{4.7*9.8*8.2}{3.6^2*7^2}

v=0.59475m/s

v \approx 0.6m/s
