Look at the picture for the answer
An object has a mass of 50.0 g and a volume of 10.5 cm3. What is the object's density?
2 answers:
Answer:
Density of object, d = 4.76 g/cm³
Explanation:
It is given that,
Mass of the object, m = 50 g
Volume of the object, V = 10.5 cm³
We need to find the density of the object. The mass per unit volume of the object is called its density. It is given by :
d = 4.76 g/cm³
So, the density of the object is 4.76 g/cm³. Hence, this is the required solution.

<h2>a)Acceleration due to gravity on the surface of the Sun is 274.21 m/s²</h2><h2>b) Factor of increase in weight is 27.95</h2>
Explanation:
a) Acceleration due to gravity
Here we need to find acceleration due to gravity of Sun,
G = 6.67259 x 10⁻¹¹ N m²/kg²
Mass of sun, M = 1.989 × 10³⁰ kg
Radius of sun, r = 6.957 x 10⁸ m
Substituting,
Acceleration due to gravity on the surface of the Sun = 274.21 m/s²
b) Acceleration due to gravity in earth = 9.81 m/s²
Ratio of gravity = 274.21/9.81 = 27.95
Weight = mg
Factor of increase in weight = 27.95
