Answer:</h2>
(a) P₂ / P₁ = 2 / 1
(b) P₂ / P₁ = 17.93 / 13
<h2>
Explanation:</h2>
At constant volume, the pressure (P) of an ideal gas is directly proportional to its temperature (T) as stated by Joseph Gay-Lussac. i.e
P ∝ T
=> P = KT
=> P / T = K
=> (P₁ / T₁) = (P₂ / T₂) = K
=> (P₁ / P₂) = (T₁ / T₂) = K
=> (P₂ / P₁) = (T₂ / T₁) = K -----------------------(i)
Where;
P₁ and P₂ are the initial and final pressures of the gas.
T₁ and T₂ are the initial and final temperatures of the gas.
(a) if temperature rises from 39 to 78 K;
This implies that;
T₁ = 39 K
T₂ = 78 K
Substitute these values into equation (i) as follows;
=> (P₂ / P₁) = (78 / 39)
=> (P₂ / P₁) = (26 / 13)
=> (P₂ / P₁) = (2 / 1)
Therefore, the ratio P₂ / P₁ = 2 / 1
(b) if temperature rises from 39.0 to 53.8 K;
This implies that;
T₁ = 39.0 K
T₂ = 53.8 K
Substitute these values into equation (i) as follows;
=> (P₂ / P₁) = (53.8 / 39)
=> (P₂ / P₁) = (17.93 / 13)
Therefore, the ratio P₂ / P₁ = 17.93 / 13
Answer:
Warming signs before fad diet includes:
1. When a special type of diet is recommended for weight loss.
2. When quick weight loss is promised instead of advice on the need to exercise, eat healthy foods including fruits and vegetables, and adopt a good feeding behavior.
3. Promises rapid weight loss in a short period of time.
After taking the fad diet the following might be experienced:
1. Constipation.
2. Weakness and fatigue.
3. More accumulation of fats in the body in the long run after a short term normal BMI (Body mass index).
4. Lower metabolic rates over time.
Explanation:
weight loss is a practice adopted by people for various reasons ranging from the desire to stay healthy to, ability to pursue a career that requires a good Body Mass Index. For instance, A BMI (Body mass index) which is equal to a person's weight (kg) / (height(m))^2 of 30 and higher is considered obese.
Fad diet which may give a temporary result of weight loss is not considered totally healthy as it doesn't capture the need to eat a healthy balanced diet instead focuses on more routine consumption of a particular kind of diet.
A healthy weight loss plan captures the need to exercise, reduce body fats while eating healthy. Eating fruits, vegetables are also encouraged.
Answer:
Squamous epithelium has cells that are wider than their height (flat and scale-like). ... Cuboidal epithelium has cells whose height and width are approximately the same (cube shaped). Columnar epithelium has cells taller than they are wide (column-shaped).
The loops must the coil have to generate a maximum emf of 2500 will be 439.
<h3 /><h3>What is the faraday law of electromagnetic induction?</h3>
According to Faraday's law of electromagnetic induction, the rate of change of magnetic flux linked with the coil is responsible for generating emf in the coil resulting in the flow of amount of current.
Given data;
Area,A = 0.239 m²
Angular velocity,ω=373 rad/sec
Magnetic field,B=0.0639 T
Maximum emf,E= 2500V
The formula for the maximum induced voltage is;
E{max} = N × B × A × ω
2500 = N × 0.639 × 0.0239 × 373
N = 438.66
N = 439 \ turns
Hence, loops must the coil have to generate a maximum emf of 2500 will be 439.
