Answer:
physical because chemical always reacts
Answer:
d. 12.30 grams
Explanation:
Given the following data;
Force = 652 N
Acceleration = 53 m/s²
To find how much the object weigh, we would need to determine its mass;
Force = mass * acceleration
652 = mass * 53
Mass = 652/53
<em>Mass = 12.30 grams.</em>
<em>Therefore, the object weighs 12.30 grams. </em>
Answer:
Yellow dwarfs are small, main sequence stars. The Sun is a yellow dwarf. A red dwarf is a small, cool, very faint, main sequence star whose surface temperature is under about 4,000 K. Red dwarfs are the most common type of star. Proxima Centauri is a red dwarf.
Explanation:
(a) The value of the gravitational acceleration is given by:

where
is the gravitational constant
M is the Earth's mass
is the Earth's radius at the pole
If we use the value for g given by the problem,
, and we rearrange the equation above, we find the value of the Earth's mass:

(b) The value we found for the Earth's mass is
, and we see that this value is slightly larger than the accepted value of
.
