Hi!me with 9 science 90 points and !

1. what causes the weight of an object to change depending on if it is on earth or the moon?

the change in mass
the distance from the sun
the distance from earth
the acceleration due to gravity
2. the mass of a mouse is around 22 grams (0.022 kg). what is the weight of a mouse at sea level on earth?

22 g
0.022 kg
22 n
0.22 n
3. the mass of a mouse is around 22 grams (0.022 kg). what is the weight of a mouse on the moon?

0.022 n
22 g
0.035 n
0.022 kg
4. the bottom of a container has an area of 25 cm2. if 6.5 newtons of water are poured into the container, what is the pressure exerted on the bottom?

0.26 n/cm^2
3.8 n/cm^2
2.6 n/cm^2
162.5 n/cm^2
5. as a fish swims deeper into the ocean, the pressure on its body . (increases, decreases)
6. use the formula for pressure to determine the weight of a box that creates a pressure of 565 n/cm^2 when resting on a 15.0 cm^2 surface.

weight = 3.84 n
weight = 377 n
weight = 37.7 n
weight = 8,475 n
7. when pressure is applied to a liquid, it will change its but not its

shape, volume
volume, shape
shape, temperature
temperature, shape
8. select all that apply. (select all that are correct, probably more then one)

hydraulic systems work because

liquids are incompressible
pressure is transmitted equally throughout a liquid
gases are incompressible
pressure and force are the same thing
9. a hydraulic system is designed to lift cars for inspection in a service station. the narrow end of the system has a surface area of 5.00 cm^2, and the lift platform (the wide end) has a surface area of 725 cm^2. if a force of 81.0 newtons is applied to the narrow end, how much upward lift force will be exerted at the wide end?

use the following formula:

(picture below)
0.559 n
11,745 n
44.75 n
293,625 n
