yes because your mass doesn't change but your weight can
ex- if you travel to Saturn your weight would change but your mass would stay the same
<h3><u>Answer;</u></h3>
Universe, galaxy, solar system, planet, moon
<h3><u>Explanation;</u></h3>
- <u>A galaxy</u>, such as our Milky Way Galaxy, is a collection of solar systems orbiting around a central core.
- <u>A solar system</u> consists of a star, normally the sun and all of its planets, asteroids, comets and other bodies.
- <u>A planet</u> is a nearly spherical body which is in orbit around the Sun. Planets are larger than moons.
- <u>Moons</u> are typically rocky bodies which are in orbit around planets.
Answer:
Weight
Explanation:
Weight is the downward pull on an object due to gravity.
For example, the moon has less gravity than Earth so we would weigh less on the moon. Our Mass and volume always stay the same but our weight could change.
Answer:
it is the impact of a meteorite, volcanic activity, or an explosion.
Answer: a) 7.1 * 10^3 N; b) -880 N directed out of the curve.
Explanation: In order to solve this problem we have to use the Newton laws, then we have the following:
Pcos 15°-N=0
Psin15°-f= m*ac
from the first we obtain N, the normal force
N=750Kg*9.8* cos (15°)= 7.1 *10^3 N
Then to calculate the frictional force (f) we can use the second equation
f=P sin (15°) -m*ac where ac is the centripetal acceletarion which is equal to v^2/r
f= 750 *9.8 sin(15°)-750*(85*1000/3600)^2/150= -880 N
