Answer:
The density of the box is 0.15 g/cm³
Explanation:
Given;
mass of the box, m = 15 g
dimension of the box, = 10 cm by 5 cm by 2 cm
Volume of the box, v = 10 cm x 5 cm x 2 cm = 100 cm³
The density of the box is given by;
Density = mass / volume
Density = 15 g / 100 cm³
Density = 0.15 g/cm³
Therefore, the density of the box is 0.15 g/cm³

Answer:
0.004 m away from the film
Explanation:
u = Object distance
v = Image distance
f = Focal length = 50 mm
The image distance is 0.051 m
When u = 50 cm
The image distance is 0.055 m
The lens has moved 0.055-0.051 = 0.004 m away from the film
Answer:
K = m g (A - A2)
Explanation:
In a block spring system the total energy is the sum of the potential energy plus the kinetic energy, for maximum elongation all the energy is potential
Em = U₀ = m g A
For when the system is at an ele
Elongation A2 less than A, energy has two parts
Em = K + U₂
K = Em –U₂
We substitute
K = m g A - m gA2
K = m g (A - A2)
