Answer:
877
Explanation:
P1 = 150 atm
V1 = 0.12 m^3
P2 = 1.2 atm
V2 = ?
radius of each balloon, r = 0.16 m
Volume of each balloon,
V2 = 0.0171 m^3
Let the number of balloons be N.
So,
P1 x V1 = N x P2 x V2
150 x 0.12 = N x 1.2 x 0.0171
N = 877.19
So, the number of balloons be 877.
1 pound ≈ 0.4536 kg
170 pounds ≈ 170 * 0.4536 kg
≈ 77.112 kg
Answer:
F₁ = F₂
Explanation:
Given that
floor pushing up on you by force F₁
gravity pulling down by force F₂
From second law of Newton's
F₁ - F₂ = m a
But here given that ,elevator is moving with constant speed .It means that acceleration of the elevator is zero.
a= 0 m/s²
F₁ - F₂ = m x 0
F₁ = F₂
