Explanation:
1. a burning candle enits radiation in the form of heat and light, this is because of it emission of energy in rays or waves
2.tea and kettle mugs transfer heat by the actual movement of matter. heat leaves the nug as the currents of the steam and air rise. This also emmits heat to the surrounding area.
3.Radiation refers to the emission of energy in rays or waves. In this, a lamps energy is emmiting rays of heat the expands its heat and light to the surrounding area.
7. the coils in the toaster heat the air which heats the toast. A toaster uses infrared radiation because when you put food in the coild glow red.
9. this is beacuse, low wavelength, non visable infared radiation can carry heat directly from warm objects to cooler objects. It emmits and expands its heat energy to the surrounding area and other objects.
To respond their enviroment,obtain and use energy,grow and develop
Because the hydra has a nervous system characterized by a nerve net other than a cockroach
Homologous chromosomes (although they may have different alleles)
Answer:
The smaller object will move at 30 m/s
Explanation:
From the principle of conservation of linear momentum,
Momentum of objects before collision = momentum of objects after collision.
where are the masses and velocities of the objects 1 and 2 respectively before collision.
Hence, the object will move at 30 m/s
