Ok so I already studied this and I realized it was water or also Oxygen
As weight =w =mg
g= gravitational acceleration on mercury = 3.7m/sec2
Mass of person =m= 70 kg
So w =(70kg)(3.7m/sec2)
w= 259 kgm/sec2
W= 259 N
Answer:
A_f= 15,769 m²
Explanation:
Este es un ejercicio de dilatación térmica,
ΔA = (2α) A₀ ΔT
el arrea de recipiente
A₀ = L A
A₀ = 3,5 4,5
A₀= 15,75 m²
el coeficiente de dilatación térmica es alfa = 16,6 10⁻⁶ C⁻¹
calculemos
ΔA = 2 16,6 10⁻⁶ 15,75 ( 40 -4)
ΔA = 522,9 (36) 10⁻⁶
A= 1,88 10⁻² m2
el cambio de volumen es
ΔA = A_f – A₀
A_f = A₀ + ΔA
A_f= 15,75 +1,88 10⁻²
A_f= 15,769 m²
Answer:
<h3>The answer is 2 s</h3>
Explanation:
The time of flight can be found by using the formula

d is the distance covered
v is the velocity
From the question we have

We have the final answer as
<h3>2 s</h3>
Hope this helps you
