When the magnification is less than 1 it means that the height of the image formed is less than that of the object.
Magnification:Magnification is defined as the ratio of the size of the image formed to the ratio of the object.
When an object is examined under a lens or a curved mirror, it produces images described by ray optics based on the position of the object from the lens or the mirror.
The image formed may be of the same size, maybe greater than the object or may be smaller based on the position and distance of the object from the lens.
If the image formed is smaller than the object then, the ratio of the height of the image to the ratio of the height of the object will be less than 1.

how does the electric force between two charged particles change if the distance between them is decreased by a factor of 3?
Answer:
F' = 9F
Explanation:
The electric force between charges is given by :
[tex]F=\dfrac{kq_1q_2}{r^2}[/tex]
It means,
[tex]F\propto \dfrac{1}{r^2}[/tex]
If distance decreased by a factor of 3, r' = r/3
Net force will become,
[tex]F'=\dfrac{kq_1q_2}{r'^2}\\\\=\dfrac{kq_1q_2}{(\dfrac{r}{3})^2}\\\\=9\dfrac{kq_1q_2}{r^2}\\\\=9\times F[/tex]
It means new force will become 9 times that of the initial force.
Answer:
it is increased by a factor of 9

How much resistance allows 6V battery to produce a current of 0.006 amps?
Answer:
It produces 1000Ω.
Explanation:
You have to apply Voltage formula, V = I × R :
V = I × R
6 = 0.006 × R
R = 6 ÷ 0.006
R = 1000Ω
We have that from the Question"How much resistance allows 6V battery to produce a current of 0.006 amps?" it can be said that How much resistance that allows 6V battery to produce a current of 0.006 amps is
R=1000 ohms
From the Question we are told
How much resistance allows 6V battery to produce a current of 0.006 amps?
Generally the equation for Resistance mathematically given as
[tex]R=\frac{V}{I}\\\\\Therefore\\\\R=\frac{V}{I}\\\\R=\frac{6}{0.006}\\\\[/tex]
R=1000 ohms
Therefore
How much resistance that allows 6V battery to produce a current of 0.006 amps is

A car accelerates from rest at a rate of 4 m/s’2 . How many seconds will it take the car to reach a final speed of 16m/s
Answer:
t = 4 [s]
Explanation:
To solve this problem we must use the following equation of kinematics.
[tex]v_{f}=v_{o}+a*t[/tex]
where:
Vf = final velocity = 16 [m/s]
Vo = initial velocity = 0
a = acceleration = 4 [m/s²]
t = time [s]
Now replacing:
[tex]16=0+4*t\\t = 16/4\\t = 4[s][/tex]

Explanation:
F = m x a. A ball of mass 0.35kg rolls on a smooth surface hits another object at rest and of mass 7kg. The second object gets an acceleration of 1.5m/s2. What acceleration does the ball get? Use newton’s third law.
Please show the working and thankyouu!!
Answer:
The acceleration the ball gets = 30 m/s²
Explanation:
The given parameters are;
The mass of the first ball that hits an object, m₁ = 0.35 kg
The mass of the object hit by the ball, m₂ = 7 kg
The acceleration given to the second object, a₂ = 1.5 m/s²
Let the a₁ represent the acceleration the ball gets
Newton's third law states that action and reaction are equal and opposite, therefore, the force exerted on a body A by a body B is equal to the force exerted on the body B by the body A;
Therefore, we have;
The force exerted on the object, F₂ = m₂ × a₂ = 7 × 1.5 = 10.5 N
The force the ball exerts on the object = F₁ = m₁ × a₁ = 0.35 × a₁
By Newton's third law, F₁ = F₂, which gives;
m₁ × a₁ = m₂ × a₂
0.35 × a₁ = 10.5
a₁ = 10.5/0.35 = 30
The acceleration the ball gets = a₁ = 30 m/s².

Why is it that a whole orange will float on water but a peeled one will sink
The peeled orange is much heavier than the water and hence it sinks and the whole orange is float as it is less denser than water.
The objects that float or sink depend on the buoyancy. Buoyancy is the tendency of the object to float in the liquids or fluids. When an object is immersed in a fluid, the object experience an upward force called buoyancy.
When the object sinks, its weight is less than the upward force or buoyancy. When the object floats, its weight is greater than the upward force.
The whole orange has a rind and the rind have tiny air pockets. When the orange is immersed in water, the water enters into the tiny air pockets and makes the orange less weight than the upward force and hence it floats.
When the rind is removed from the orange, the water can not enter the orange. Thus, the weight of the orange is greater than the upward force. Hence, it sinks.
