The mass of each sphere is m=1.7kg
<h3>What is the mass?</h3>
The amount of matter in a particle or object is represented by the dimensionless quantity mass (symbolized m). The kilogram is the chosen unit of mass according to the International System (SI) (kg).
<h3>According to Given Information:</h3>
We'll apply the formula.
Now take note that the value we must discover is m1 = m2 = m. When m is solved for,
m=1.7kg is obtained using the formulas Fg = 2.0 109 N and G = 6.673 1011 N m2/kg2.
<h3>What is the force?</h3>
A force refers to the push or pull that such an object feels when it comes into contact with another object. A force is applied to each object when two things come into contact. The interaction between the two items stops when the force is no longer looks by either.

Answer:
60 cm²
Explanation:
Pressure = Force / Surface area
This is a 2 stage problem which requires working out pressure of piston A and then using that pressure from piston A to calculate the surface area of piston B
Firstly work out pressure of Piston A:
Pressure = 200 / 4
Pressure = 50 N/cm²
Then work out the Surface area of piston B :
Since the pressure is transferred the pressure stays the same so :
Surface area = Force / Pressure
Surface area = 3000 / 50
Surface area = 60 cm²
Units is the correct answer
Answer:
= 1.75 × 10⁻⁴ m/s
Explanation:
Given:
Density of copper, ρ = 8.93 g/cm³
mass, M = 63.5 g/mol
Radius of wire = 0.625 mm
Current, I = 3A
Area of the wire, 
= 
Now,
The current density, J is given as
= 2444619.925 A/mm²
now, the electron density, 
where,
=Avogadro's Number
Now,
the drift velocity,
where,
e = charge on electron = 1.6 × 10⁻¹⁹ C
thus,
= 1.75 × 10⁻⁴ m/s
