Answer:
17867.36 Pa
Explanation:
height, h = 1.72 m
density of blood, d = 1.06 x 10^3 kg/m^3
acceleration due to gravity, g = 9.8 m/s^2
Pressure P = h x d x g
P = 1.72 x 1.06 x 1000 x 9.8
P = 17867.36 Pa
Answer:
v = 12.3 m / s
Explanation:
This is an exercise in kinetics in one dimension
v² = v₀² + 2 a x
In this exercise they tell us that the initial velocity is (v₀ = 13 m / s), the acceleration is a = -0.95 m / s2 and the distance x = 9.2 m
we substitute
v = √ (13 2 - 2 0.95 9.2)
v = 12.3 m / s
note that as the acceleration is negative the vehicle is stopping
Answer:
V * ρB = WB volume of ball * density of ball = weight of ball
V * ρW = Ww volume of ball * density of water = buoyant force
ρB / ρW = WB / Ww = 80 / 20 = 4 water provides 20 N of buoyant force
ρB = 4 ρW = 4 gm/cm^3
ρW = 1000 kg / m^3 = 1 gm / cm^3
(1 gm/cm^3) = .001 kg / .000001 m^3 = 1000 kg/^3
ρW = 1 gm / cm^3
multiply by 9.8 or 980 to get weight densities
In this case
4 * 1000 kg/m^3 * 9.8 m/s^2 = 39200 N /m^3 weight density of ball
All of the following are examples of physical properties except tearing.

What is Physical property?</h3>
This is used to describe the state of a physical system and is usually measurable.
Examples include:
Tearing isn't an example of a physical property which was why option A was chosen as the most appropriate choice.
