Answer:
![F=19.8kN=4442lb](https://tex.z-dn.net/?f=F%3D19.8kN%3D4442lb)
Explanation:
On Earth the atmospheric presure is
. This will be the pressure inside the lander. Outside, the pressure on Mars will be
. This means that the net force will be outward (since inside the pressure is higher) and, since the area of the hatch is
, of value:
![F=(P_E-P_M)\pi r^2=(101325N/m^2-650N/m^2)\pi (\frac{0.5m}{2})^2=19768N=19.8kN](https://tex.z-dn.net/?f=F%3D%28P_E-P_M%29%5Cpi%20r%5E2%3D%28101325N%2Fm%5E2-650N%2Fm%5E2%29%5Cpi%20%28%5Cfrac%7B0.5m%7D%7B2%7D%29%5E2%3D19768N%3D19.8kN)
Since 1lb in weight is equal to 4.45N, we can write:
![F=19768N=19768N\frac{1lb}{4.45N}=4442lb](https://tex.z-dn.net/?f=F%3D19768N%3D19768N%5Cfrac%7B1lb%7D%7B4.45N%7D%3D4442lb)

Answer:
Explanation:
From the question we are told that
The initial pressure of the gas is ![P_1 = 1.50 \ atm](https://tex.z-dn.net/?f=P_1%20%3D%20%201.50%20%5C%20%20atm)
The volume of the second bulb is ![V_2 = 0.800 \ L](https://tex.z-dn.net/?f=V_2%20%3D%20%200.800%20%5C%20%20L)
The final pressure of the gas is ![P_2 = 671 \ torr = \frac{671 }{ 760} = 0.883 \ atm](https://tex.z-dn.net/?f=P_2%20%3D%20%20671%20%5C%20torr%20%3D%20%20%5Cfrac%7B671%20%7D%7B%20760%7D%20%20%3D%20%200.883%20%5C%20atm)
Let the unknown volume be represented as
Generally from Boyle's law we have that
![P_1 * V_1 = P_2 * V_2](https://tex.z-dn.net/?f=P_1%20%2A%20%20V_1%20%3D%20%20P_2%20%2A%20V_2)
=> ![1.50 * V = 0.883 * 0.800](https://tex.z-dn.net/?f=1.50%20%2A%20%20V%20%3D%20%20%200.883%20%20%2A%200.800)
=> ![V = 0.479 \ L](https://tex.z-dn.net/?f=V%20%20%3D%200.479%20%5C%20L)
Answer:transverse- transfers energy perpendicular to the direction of the wave
Electromagnetic- dose not require a medium for transition
Mechanical - requires a medium for transmission
Longitudinal- transfers energy parallel to the direction of the wave
Explanation: just took the activity
Answer:
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
Example: Radio waves, microwaves, visible light, and x rays
