Answer:
1. 0.98 atm
Explanation:
The following data were obtained from the question:
Mass of unknown liquid (m) = 0.3175 g
Temperature (T) = 99 °C
Pressure (P) = 748.2 mmHg
Volume (V) = 145.0 mL
Gas constant (R) = 0.08206 atm.L/Kmol
1. Determination of the pressure in atm.
760 mmHg = 1 atm
Therefore,
748.2 mmHg = 748.2/760 = 0.98 atm
Therefore, the pressure in atm is 0.98 atm.
Explanation:
The states may differ depending on the reactions
Taking into account the Newton's second law, the correct answer is option A. F = 9.68 N right
In first place, acceleration in a body occurs when a force acts on a body.
Newton's second law states that a force will change the speed of an object because the speed and/or direction will change. These changes in velocity are called acceleration.
So, Newton's second law defines the relationship between force and acceleration mathematically. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object
Mathematically, Newton's second law is expressed as:
F= m×a
where:
- F = Force [N]
- m = Mass [kg]
- a = Acceleration [m/s²]
In this case, you know:
- F= ?
- m= 2.2 kg
- a= 4.4 m/s²
Replacing in Newton's second law:
F= 2.2 kg× 4.4 m/s²
Solving:
<u><em>F= 9.68 N</em></u>
Finally, As the bowl of fruit accelerates to the right, the correct answer is option A. F = 9.68 N right

1. The bird has to adjust where it doves in for the fish because the light is refracted by the water, making it look like the fish is in a different position than it is.
2. The clock is reflected in the mirror, which sends each part of the image straight back.
4. Your first part is correct. The second part: The plant would look dark brown or black and red light. Red light has no green wavelengths to reflect, and the red light would be absorbed by the leaf, making it appear almost black.
