Answer:
When you experience prolonged stress, your body needs those T-cells and white blood cells, and unfortunately, cortisol continues to suppress them, thus weakening your immune system over time.
Explanation:
Stress, Illness and the Immune System. ... When we're stressed, the immune system's ability to fight off antigens is reduced. That is why we are more susceptible to infections. The stress hormone corticosteroid can suppress the effectiveness of the immune system
Answer:
The time taken to travel is, t = 12 minutes
Explanation:
Given data,
The speed of the car, v = 60 km/h
The distance of travel, d = 12 km
The time taken for the travel is t = ?
The speed is defined as the distance divided by the time taken to travel. The formula for speed is,
v = d/t
∴ t = d/v
t = 12 km / 60 km/h
t = 0.2 h
t = 12 minutes
Hence, the time taken to travel is, t = 12 minutes.
Answer:
211 mmHg
Explanation:
Absolute Pressure = Gauge Pressure + Atmospheric pressure
128 = Gauge Pressure + 100
Gauge Pressure = 28 KPa = 28 × 10³ Pa
Also Gauge Pressure = ρgh
ρ = density = 13550 kg/m³
g = acceleration due to gravity = 9.8 m/s²
h = pressure head = ?
28 × 10³ = 13550 × 9.8 × h
h = 28000/(13550 × 9.8)
h = 0.211 m = 211 mm
You need to convert minutes to hours so
