In a collision between an electron and a hydrogen atom, it is useful to select both objects as the system because which of these
lukranit [14]

Answer:

Explanation:

Because of the following ,it is useful to select both objects as the system during  collision between an electron and a hydrogen atom

1. The total momentum of the system does not change during the collision.

2.The forces the objects exert on each other are internal to the system and don't change the total momentum of the system.

3. During the time interval just before to just after the collision, external forces are negligible.

A fugitive tries to hop on a freight train traveling at a constant speed of 5.5 m/s. Just as an empty box car passes him, the fu
stiks02 [169]
Th equations to be used here are the following:

a = (v - v₀)/t
x = v₀t + 0.5at²

The speed of the fugitive is the sum of his own speed plus the speed of the train. Thus, 
v₀ = 0 + 5.5 m/s = 5.5 m/s
v = 8 m/s + 5.5 m/s = 13.5 m/s

a.) We use the first equation to determine time
2.5 m/s² = (13.5 m/s - 5.5 m/s)t
Solving for t,
t = 3.2 seconds

b.) We use the answer in a) and the 2nd equation:

x = (5.5 m/s)(3.2 s) + 0.5(2.5 m/s²)(3.2 s)²
x = 30.4 meters

A sealed pressure cooker allows steam to escape only through an opening in the lid. a separate metal object, called a petcock, s
daser333 [38]

The mass of the petcock of the pressure cooker is  0.257 kg.

The total pressure inside the cooker is= atmospheric pressure+Gauge pressure

=100 kPa+101 kPa=201*10^3 Pa

The area of the petcock is= (π/4)d^2=0.785*0.004^2=12.56*10^(-6) m^2

Now the mass of the petcock is calculated as

P=(F/A)=(mg/A)

201*10^3=(m*9.81/(12.56*10^(-6)

m=0.257 kg

Therefore the mass of the petcock is 0.257 kg
