Answer:

by using it's buoyant or floating effect by Archimedes.

the buoyant force act on the astronauts body and make he/ she feels like in low gravity.

the buoyant force equation is

F = Density of liquid x earth gravitational field x volume of astronauts body and suit.

the Weight of astronauts in the pools will be less than in the land or air.

Weight in water = weight in air/land - buoyant force

so the astronauts will feel like in the outer space with low gravity.

A space traveler discovers that her weight on a new planet is 192 newtons. Her mass is 68 kilograms. What is the gravitational a

alina1380 [7]

Answer:

g ≈ 2.82 m/s^2

Explanation:

By W = mg,

W = weight (in newtons)

m = mass (in kg)

g = gravitational acceleration (in m/s^2)

$192 = 68g$

$g = 2.82352941176 m/s^2$

g ≈ 2.82 m/s^2

A 175-kg motorcycle goes around an unbanked turn of radius 75.4 m at a steady 112 km/h. Determine its acceleration?

Nuetrik [128]

Answer: $12.83 m/s^{2}$

Explanation:

In this case we are talking about the centripetal acceleration $a_{c}$ , which can be calculated by:

$a_{c}=\frac{V^{2}}{r}$

Where:

$V=112 \frac{km}{h} \frac{1000 m}{1 km} \frac{1h}{3600 s}=31.11 m/s$ is the speed of the motorcycle

$r=75.4 m$ is the radius of the path the motorcycle is going around

Solving:

$a_{c}=\frac{(31.11 m.s)^{2}}{75.4 m}$

Finally:

$a_{c}=12.83 m/s^{2}$
