The magnitude of acceleration, is the same. You are probably thinking about centripetal force F=mv^2/r. But the question asks about the centripetal acceleration ac=v^2/r of the ride. The rides velocity and radius remains constant so the magnitude of acceleration of the ride is the same for both adult and child

How would you describe the appearance of the substance after the phase change?
Leona [35]

Answer:

Substances can change phase—often because of a temperature change. At low temperatures, most substances are solid; as the temperature increases, they become liquid; at higher temperatures still, they become gaseous. The process of a solid becoming a liquid is called melting.

How does the area of ​​0.3 m2 of iron change when heated from 20 ° C to 60 ° C?
DerKrebs [107]

Answer:

The quantitative relationship between heat transfer and temperature change contains all three factors: Q = mcΔT, where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC. The specific heat c is a property of the substance; its SI unit is J/(kg ⋅ K) or J/(kg ⋅ ºC). Recall that the temperature change (ΔT) is the same in units of kelvin and degrees Celsius. If heat transfer is measured in kilocalories, then the unit of specific heat is kcal/(kg ⋅ ºC).
