Answer:
Absolute error = 1.06 m
Relative error = 0.02
Explanation:
When considering 51 m the distance between two points actually located at 52.06 m which is the absolute and relative error.
Given that the actual distance between the two points is 52.06 m
Considered distance = 51 m
Error = Actual value - Measured value
=52.06m - 51m
=1.06m
The value is already positive, so the absolute error is also 1.06m.
Relative error =( error)/(actual value)
=1.06/52.06=0.02
Hence the relative error is 0.02.
Microscope
A microscope shines a light through a slide with the sample of the object on and you look through a lens that allows you to magnify it by a very significant amount depending on what kind of microscope you have (a powerful electron microscope can magnify to the atomic level).
Answer:
Explanation:
A free-body diagram is a sketch of an object of interest with all the surrounding objects stripped away and all of the forces acting on the body shown. The drawing of a free-body diagram is an important step in the solving of mechanics problems since it helps to visualize all the forces acting on a single object. The net external force acting on the object must be obtained in order to apply Newton's Second Law to the motion of the object.
A free-body diagram or isolated-body diagram is useful in problems involving equilibrium of forces.
Free-body diagrams are useful for setting up standard mechanics problems.
Momentum is described as the result of the calculation of mass multiplied by that thing's velocity.
<span>
In equational formula we can write it: </span>
<span>
P (momentum) = m(mass) * v(velocity) </span>
so to find the mass, revert the equation:
<span>
P = m v </span>
m = P / v
now for the value entry,
<span>
m = 2.5 * 10^4 kgm/s / 30 m/s </span>
<span>
m = 8,3 * 10^2 kilograms

Answer:
0.62 m/s² at 68° S of E
Explanation:
Net force north = 12 - 70 = -58 N
Net force east = 33 - 10 = 23 N
Net force = √(-58² + 23²) = 62.3939... N
acceleration = F/m = 62.3939/100 = 0.623939... ≈ 0.62 m/s²
θ = arctan(-58/23) = -68.3691... ≈ 68° S of E
