Yes it helps improve flexibility
If it i hot it makes it easy to clean
Answer:
4.42 x 10⁷ W/m²
Explanation:
A = energy absorbed = 500 J
η = efficiency = 0.90
E = Total energy
Total energy is given as
E = A/η
E = 500/0.90
E = 555.55 J
t = time = 4.00 s
Power of the beam is given as
P = E /t
P = 555.55/4.00
P = 138.88 Watt
d = diameter of the circular spot = 2.00 mm = 2 x 10⁻³ m
Area of the circular spot is given as
A = (0.25) πd²
A = (0.25) (3.14) (2 x 10⁻³)²
A = 3.14 x 10⁻⁶ m²
Intensity of the beam is given as
I = P /A
I = 138.88 / (3.14 x 10⁻⁶)
I = 4.42 x 10⁷ W/m²
Answer:
3.8 km
Explanation:
Eastern Side Bus
Velocity = 20m/s
Covers distance in 2 min (120sec) = 20×120 = 2400m = 2 km
Western Side Bus
Velocity = 15m/s
Covers distance in 2 min (120sec) = 15×120 = 1800m = 1.8 km
Separation Distance = 2+1.8 = 3.8 km
