Answer:
22.36 rad
Explanation:
Applying,
ω = θ/t.............. Equation 1
Where ω = angular velocity, θ = angular displacement of the baseball, t = time
make θ the subject of the equation
θ = ωt............... Equation 2
From the question,
Given: ω = 350 rev/min = 350(0.10472) = 36.652 rad/s, t = 0.61 s
Substitute these values into equation 1
θ = 0.61(36.652)
θ = 22.36 rad
Hence the angular displacement of the baseball is 22.36 rad

Answer:
11.6 g/m³
Explanation:
The complete question is,
The device shows the relative humidity at 22 degrees celsius. What's the water vapor density if the maximum water vapor in air at this temperature is 20 gram/cubic meter? a device showing that at 22 degrees celsius the relative humidity is 58%.
Solution:
saturation of water in air is showed by the relative humidity. As it is 58% and not 100%. Lets scale density that we have, if humidity is 100%.
density is 20 gram/m³ when the humidity is 100%
When humidity is 58%
0.58 x 20 = 11.6 g/m³
Therefore, density is 11.6g/m³
Answer:
The answer is c) while the statement is false, the given reasons for it being false are incorrect.
Explanation:
The speed of a chemical reaction must be proportional to the number of molecules per unit of time with enough energy to achieve the transition state. This transition state has an energy superior to that of the reagents and that of the products, establishing among them an energy barrier that has to be overcome in order for the reaction to take place.
