How do you calculate an
object's displacement?

Answer:
Wecanuseequationsofmotion
Answer:
Displacement can be calculated by measuring the final distance away from a point, and then subtracting the initial distance. Displacement is key when determining velocity (which is also a vector). Velocity = displacement/time whereas speed is distance/time.

Answer:The newly formed oxygen ion is negatively charged.
Explanation:
Cation : These are species of ions which carries positive charge that is number of protons are greater than the number of electrons.
Anion:These are species of ions which carries negative charge that is number of electrons are greater than the number of protons.
When an oxygen atom gains two electrons it develops the charge of negative charge and forms anion.
hope this helps :)

Answer:
30 m³
Explanation:
Parameters given:
Initial volume of helium, V1 = 5 m³
Initial pressure in balloon, P1 = 30 kPa
Final pressure, P2 = 5 kPa
To find the volume of the balloon at that volume, we apply Boyle's law.
It states that at constant temperature, the pressure of a gas is inversely proportional to the volume of the gas.
Mathematically:
P = k / V
Where k = constant of proportionality
This implies that:
P * V = k
This means that if the pressure or volume of the gas changes at the same temperature, the product of the pressure and volume would be the same:
Hence:
P1 * V1 = P2 * V2
Hence, to find the final volume:
30 * 5 = 5 * V2
=> V2 = (30 * 5) / 5
V2 = 30 m³
The volume of the gas when the pressure is 5 kPa is 30 m³.

Explanation:
Carrying a heavy bag with a string of wire can cause more pain compared to carrying a bag without a string of wire due to a few reasons.
Firstly, the presence of the string of wire adds additional pressure and strain on your hand, making it harder to grip and carry the bag comfortably. The wire can dig into your skin and cause discomfort or even pain. Imagine holding a bag with a smooth handle versus holding a bag with a sharp wire cutting into your hand - the latter would definitely be more painful.
Secondly, the wire can create friction against your skin. As you carry the bag and walk, the movement can cause the wire to rub against your hand, resulting in irritation and potentially even blisters. This friction can also cause the wire to dig deeper into your skin, intensifying the pain.
Lastly, the weight distribution of the bag can be affected by the presence of the wire. When you carry a heavy bag, it is ideal for the weight to be evenly distributed to minimize strain on specific areas of your body. However, the wire can create an uneven distribution of weight within the bag. This can lead to increased pressure and discomfort on certain parts of your hand, making it more painful to carry the bag.
In summary, carrying a heavy bag with a string of wire can hurt more due to the additional pressure and strain on your hand, the friction caused by the wire rubbing against your skin, and the uneven weight distribution within the bag. It is important to consider these factors when carrying heavy objects to minimize discomfort and potential injury.
