You are kicking your soccer ball back and forth on a soccer field. You kick the ball forward for 10 m. You turn completely aroun
Evgesh-ka [11]

Answer:

1.) Total distance = 70 m

2.) Total displacement = +30m

Explanation:

Distance is a scaler quantity. That is, we will be concerned about its magnitude only and not direction.

Total distance = 10 + 20 + 40 = 70 m

While displacement is a vector quantity. We will consider both the magnitude and its direction.

Forward direction will be positive while backward direction will be negative

Total displacement = +10 - 20 + 40

Total displacement = +30 m

"A bridge, constructed of 11 beams of equal length L and negligible mass, supports an object of mass M.
fiasKO [112]
F_P  + F_Q = M g
F_P = M g - F_Q
Torque, or moment of force:
∑ M_P = 0
∑ M_P = M g L - F_Q · 3 L
0 = M g L - 3 F_Q L         / : L
0 = M g - 3 F_Q
3 F_Q = M g
F_Q = M g /3
Finally:
F_P = M g - M g/3
F_P = 4 M g / 3

Does the galvanometer deflect to the left or the right when:________
igomit [66]

Complete question is;

Does the galvanometer deflect to the left or the right when

a) the magnet is being pushed in

b) the magnet is being pulled out

c) the magnet is being held steady?

Answer:

Option A - when the magnet is being pulled out

Explanation:

Faraday’s law of electromagnetic induction states that: “Voltage is induced in a circuit whenever relative motion exists between the conductor and the magnetic field, and the magnitude of the voltage will be proportional to the rate of change of the flux”.

Now, applying it to the question, When the magnet is moved towards the sensitive center of the galvanometer and then pulled out, the needle of the galvanometer will deflect away from its center position in one direction only but when it is held steady, the needle of the galvanometer will return back to zero.
