D, because the hairdryer uses a fan
E, because it produces heat

Answer from: DJEMPGYT

Answer;

D.) motion energy

E.) radiant energy

Explanation;Energy is the ability to do work. From the law of conservation of energy, energy can not be created nor destroyed by may be transformed from one form to another. Instruments or devices which converts energy from one form to another are called transducers.Hair dryer is an example of a transducer which converts electrical energy to either thermal or heat energy and also to kinetic energy. Electrical energy entering the hair dryer is converted to kinetic energy or motion energy as the small electric motor in the dryer spins a fan blade. Additionally, electrical energy is also converted into heat or thermal energy in a grid of wire that heats up. The fan pushes air across the hot wires, and hot air blows out the nozzle of the hair dryer.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

Isobars are lines of constant or equal pressure on a weather map. they can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. on weather maps, you may have noticed areas that have a large l or h over a region with lines circling around them. the l stands for low pressure and h stands for high pressure. the lines circling them are isobars. check out the pressure system and isobars over georgia and florida. what is the present weather in this area ? a) clear and sunny b) cold and cloudy c) changing weather d) lots of precipitation
