Answer:
endothermic energy or chemical energy
Explanation:
An endothermic process increases the enthalpy H of the system, during which the closed system (usually) absorbs thermal energy from its surroundings.
Chemical energy is the form of potential energy in which energy is stored in chemical bonds. The breaking of chemical bonds absorbs energy, while the formation of new bonds releases energy.

Ultraviolet radiation can kill bacteria that are present in water - this sterilises the water and makes it safe to drink.
It goes in this order. Medium, density, viscosity
Answer:

Explanation:
Initial angular speed of the ferris wheel is given as



final angular speed after friction is given as



now angular acceleration is given as



now torque due to friction on the wheel is given as
