Answer:
5.3 cm
Explanation:
This question is an illustration of real and apparent distance.
From the question, we have the following given parameters
Real Distance, R = 8.0cm
Refractive Index, μ = 1.5
Required
Determine the apparent distance (A)
The relationship between R, A and μ is:
μ = R/A
i.e.
Refractive Index = Real Distance ÷ Apparent Distance
Substitute values in the above formula
1.5 = 8/A
Multiply both sides by A
1.5 * A = A * 8/A
1.5A = 8
Divide both side by 1.5
1.5A/1.5 = 8/1.5
A = 8/1.5
A = 5.3cm
Hence, the letters would appear at a distance of 5.3cm
cause an object to accelerate in a direction opposite to the unbalanced force
Explanation:
An unbalanced force is defined as any force that causes an object to accelerate in a direction opposite to the unbalanced force.
The unbalanced force is the net or resultant force describe in newton's second law of motion.
In the first law, it is the external force that causes the motion of a body to change.
Unbalanced forces can cause body to either accelerate in the direction of the force or in an opposite direction of the force.

Force = (mass) x (acceleration)
Mass = (force) / (acceleration)
There was 150N of force in one direction and 100N of 'force' in
the other direction. The net force on the object was (150 - 100) = 50N .
Acceleration = (change in speed) / (time for the change)
= (10 m/s) / (5s) = 2 m/s²
Mass = (net force) / (acceleration) = (50 N) / (2 m/s²) = 25 kilograms
That is false. A GPS cant tell latitude and longitude
The change in distance is 30 because if you subtract both number you'll get 30
