The answer is the particles move faster
Answer:
T₂ = 111.57 °C
Explanation:
Given that
Initial pressure P₁ = 9.8 atm
T₁ = 32°C = 273 + 32 =305 K
The final pressure P₂ = 11.2 atm
Lets take the final temperature = T₂
We know that ,the ideal gas equation
If the volume of the gas is constant ,then we can say that
Now by putting the values in the above equation ,we get
T₂ = 384.57 - 273 °C
T₂ = 111.57 °C
Force = mass * acceleration
acceleration = change_in_velocity / time
so:
force = 740 kg * (19 m/s - 0 m/s) / 2.0 s
= 740 * 19 / 2 kg m per second^{2}
= 7030 kg m per second^{2}
= 7030 newtons of force
Answer:
<em>6.8 Kg m/s</em>
Explanation:
<u>Linear Momentum</u>
The linear momentum is defined as the product of the velocity of an object by its mass
P=mv
It's a vectorial magnitude, but if we use its equivalent scalar equation, then v is the speed
The measured speed of a pitch by Aroldis Chapman is v=47 m/s. The ball has a mass of m=145 gram=0.145 Kg. The maximum momentum of the ball was
P=(0.145 Kg)(47 m/s)=6.8 Kg m/s
The options don't show the units of the momentum, but we assumed to be Kg m/s, so the correct option is the third one
