The answer is the first option "true." According to social exchange theory, altruistic behaviors benefit the individual who performs them is a true statement. That is because the word Altruism means doing acts to benefit themselves.
Hope this helps.
Answer:
Explanation:
electron attraction between electron and nucleus = centripetal force of the orbiting electron
In fact, Bohr model depicts the atom as a nucleus surrounded by electrons in circular orbit around it, similar to the planets around the Sun. The centripetal force that keeps the electrons in circular motion around the nucles is provided by the electrostatic force between the electrons and the nucleus.

time taken to cook one burger is given as
now we can find the speed of the belt as
Now we know that the distance between two burgers is given as 25 cm

B.
srry for short answer :)
This problem can be assume that the two railroad cars are moving toward each other, and not in opposite direction, because of the condition of an head collision.
Given: Mass of Car₁ = 6,500 Kg; Mass of Car₂ = 6,500 Kg
Velocity of each Car V = 80 Km/h or 22.22 m/s
Required: Thermal energy or Total Kinetic energy
Formula: K.E = 1/2 MV²
Solution: Total Kinetic energy or Tke = (1/2 MV²)car₁ + (1/2 MV²)car₂
Tke = 1/2 (6,500 Kg)(22.22 m/s)² + 1/2 (6,500 Kg)(22.22 m/s)²
Total Thermal energy or Tke = 3,209 Joules
