Answer:
v (speed) = S / t = 4 * 400 m / (6 * 60 sec) = 4.4 m/s
The average velocity is zero because there is no net vector displacement.
Volcanic activity is likely to happen when two plates pull apart form one another. When the surface of the Earth is separated, the magma within will pour out.
Answer: B. Volcanic Activity
Answer:
c. Both Technicians A and B
Explanation:
ABS stands for anti lock braking system. It prevents the vehicle to skid while braking action in slippery surfaces and prevents lockup of the wheels.
The ABS ban be bled using a bleeder screw. Bleeding the brake means removing the air inside for a firm brake pedal. Thus to remove the air, open the bleeder screw of the ABS and allow to pass the air out while turning on the engine.
A fully featured scan tool is required to fully bleed the air in the ABS system. The bi-directional control of the modulator can purge air bubbles out that can not be done with normal bleeding.
Thus both technician A and technician B are correct.
Answer:
If there is a voltage source connected to the wire, the current will decrease as per Ohm's Law.
Explanation:
Supposing that there is a battery that provides potential difference to the ends of the wire, the actual current will decrease from the previous situation, according to Ohm's Law: 
From this equation, with a constant V of the power source as the resistance "R" increases (larger in the denominator of that rational expression) the current "I" will decrease.
