Answer:
Many metals (such as zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on the oxidation states of the oxide. Al2O3 is an example of an amphoteric oxide.
Answer:
5N Left (the direction of friction)
Explanation:
Looking at the normal force and the gravitational force, they are both of equal magnitude (3N), and are in opposite directions ( up and down). This means they cancel out - their overall force is 0.
Moving on to the sideways forces, we only have friction (5N). There is no force to the right to cancel this out, so the overall force must be 5N left.
Hope this helps! Let me know if you have any questions :)
Mr. Harrison is most likely a meteorologist.
Meteorologists study the atmosphere and weather patterns and predict weather using computers and mathematical models. Meteorologists are using information they collect from the land, water and atmosphere (temperature, pressure, humidity) to study weather conditions.
