Answer:
105.1N
Explanation:
According to the newton second law
Since the acceleration is zero, then;
Since;
Given the following
mass of ladder m = 14kg
acceleration due to gravity g = 9.8m/s²
θ = 50°
Substitute
Hence the magnitude of the friction force (in N) exerted on the ladder in the point of contact with the horizontal surface is 105.1N
Answer:
P2 = 128,205 pascal.
Explanation:
<u>Given the following data;</u>
Original Pressure, P1 = 100,000 pascals
Original Temperature, T1 = 273K
New Temperature, T2 = 350K
To find new pressure P2, we would use Gay Lussac' law.
<em>Gay Lussac's law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas. </em>
Mathematically, Gay Lussac's law is given by;
Where;
- P represents pressure.
- T represents temperature.
- K is the constant of proportionality.
<em>Making P2 as the subject formula, we have;</em>
Substituting into the equation, we have;
P2 = 128205.13 ≈ 128205 pascal.
<em>Therefore, the pressure inside the hot water bottle is 128,205 pascal. </em>
