Which function is decreasing?

1 answer:

5 0

The function which is decreasing is C. <span>Air pressure in the earths atmosphere as a function of altitude.
The higher you go, the less air pressure there is because of the fewer air molecules at such altitudes.
This means that the remaining functions are either constant or increasing. </span>

Discuss velocity by providing at least one example and explain why velocity is either a scalar or vector quantity.

grandymaker [24]

Velocity is speed plus direction, so an example of velocity would be a vehicle traveling at 75mph north. Velocity is a vector quantity because it describes both magnitude and direction.

A mother has four times the mass of her young son. Both are running with the same kinetic energy. Part A What is the ratio vs/vm

valentinak56 [21]

Answer: 2:1

Explanation:

Given

Mother has four times the mass of young son

If they possess same kinetic energy then $K_m=K_s$

$\Rightarrow K_m=\dfrac{1}{2}\times m_m\times v^2_m$

$\Rightarrow K_s=\dfrac{1}{2}\times m_s\times v^2_s$

Equate the energy

$\Rightarrow \dfrac{1}{2}\times m_m\times v^2_m=\dfrac{1}{2}\times m_s\times v^2_s\\\\\Rightarrow \dfrac{1}{2}\times 4m_s\times v^2_m=\dfrac{1}{2}\times m_s\times v^2_s\\\\\Rightarrow 4 v^2_m=v^2_s\\\\\Rightarrow \dfrac{v_s}{v_m}=\sqrt{4}\\\\\Rightarrow \dfrac{v_s}{v_m}=2$
