Answer:
An insulator
Explanation:
Insulators have a very high resistance because the electrons of the insulator are bounded strongly with the nucleus. Hence it requires more voltage to move an electron from the valence band to the conduction band.
opposite to the net force

opposite to motion
The friction arrow in an FBD for a moving object point is in opposite way to motion. Because friction always works in the opposite direction of the motion of the object.
Answer: Option D
Explanation:
When two object come into contact, the contact force come into play. Now, one component of the contact force i.e. the normal forces act perpendicularly at the direction of motion. Whereas, the frictional forces always acts parallel at the direction of the force acting on the object but in the opposite way.
For example, if we slide a book on the table to the right hand side, the exact equal and opposite frictional force will induce in the opposite direction, tempting to reduce the motion.
Answer:
Average speed = 0.0075 m/s
Average velocity = 0.0025 m/s along forward direction
Explanation:
Speed is the ratio of distance and time and velocity is the ratio of displacement and time.
Distance traveled = 10 + 5 = 15 cm = 0.15 m
Displacement = 10 - 5 = 5 cm = 0.05 m
Time = 20 seconds
Average speed = 0.0075 m/s
Average velocity = 0.0025 m/s along forward direction
Hey!
---------------------------------------------------
Formula: Distance / Time = Speed
---------------------------------------------------
Solution:
Speed = 15/20 = 0.75cm/sec
Velocity = 5/20 = 0.25cm/sec
10 + 5 = 15 (distance traveled)
---------------------------------------------------
Answer:
Speed = 0.75cm/sec
Velocity = 0.25cm/sec going forward.
