This can be seen as a trick question because heat engines can typically never be 100 percent efficient. This is due to the presence of inefficiencies such as friction and heat loss to the environment. Even the best heat engines can only go up to around 50% efficiency.
Answer:
O- to track how fast a heart beats
Explanation:
Answer:
C. The number of shells increases from top to bottom
Explanation:
There are some trends about the periodic table, one of them is that in the vertical columns of periodic table, the number of shells increases from top to bottom.
From top to bottom in a periodic table, the number of electrons increases, thus more number of shells are needed to fill these electrons and the number of shells increases or we can say the atomic radius increases from top to bottom.
Hence, the correct option is "C".
The horizontal motion of a launched projectile affects its vertical motion is false
Answer: False
<u>Explanation:
</u>
As the trajectory falls on a plane, all the components like displacement, velocity can be classified in two components termed as horizontal and vertical component.
In a projectile motion, the horizontal components of displacement and velocity remains constant and there is change only in the vertical component of displacement and velocity.
Both components are not dependent to each other. So, the horizontal motions of a launched projectile does not affect its vertical motion.
