A turtle swimming in a straight line toward shore has a speed of 0.50 m/sec. After 4.0 seconds, its speed is at 0.90 m/sec. What is the turtle's
acceleration?

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
