Answer:
The tropospheric tabulation continues to 11,000 meters (36,089 ft), where the temperature has fallen to −56.5 °C (−69.7 °F), the pressure to 22,632 pascals (3.2825 psi), and the density to 0.3639 kilograms per cubic meter (0.02272 lb/cu ft). Between 11 km and 20 km, the temperature remains constant

<u>Answer</u>:
The radiant energy is converted into<u> electronic energy</u> before it is transformed into thermal energy.
<u>Explanation</u>:
Radiant energy occurs in the form of "Electromagnetic radiation" and it can pass through all types of matter travelling through the universe. There are numerous advantages of radiant energy. When the radiant energy is incident upon a substance the energy from the sun light excites the electrons in the atom. This sets the atoms in vibrational motion.
Thermal energy is the kinetic energy of moving particles. The thermal energy increases with increase in movement and number of moving particles. When the atoms make a transition from electronically excited state to vibrational state, the energy transfer increases the temperature of the substance. This is felt as thermal energy. Hence, the radiant energy is changed into "electronic energy" before it is converted into "thermal energy".
The work done was done by friction to keep the crate from moving as the truck came to a stop is 20,000 J.
<h3>
Work done by friction to prevent the crate from moving</h3>
The work done is determined by applying the principle of conservation of energy.
W = K.E
W = ¹/₂mv²
where;
- m is mass of crate
- v is speed of the crate with respect to the truck = 20 m/s
W = ¹/₂(100)(20²)
W = 20,000 J
Thus, the work done was done by friction to keep the crate from moving as the truck came to a stop is 20,000 J.
