A researcher rolls some clay into a ball and shows it to Zian, then squishes the clay into a pancake. Zian understands that the

amount of clay is the same in both. The researcher makes a row of 10 coins, then makes another row of 10 coins beneath it but spreads out the row so the coins are farther apart. Zian says the spread-out row has more coins in it. This seems to confirm the phenomenon Piaget called:

How does the electric force between two charged objects on the charges of the objects
Mariulka [41]

Answer:

If one charged object is positive, and the other charged object is negative, then the two objects will attract each other. If both objects are positive, the objects will repeal each other. If both objects are negative, the objects will also repeal each other.

V - the wind velocity;
53° - 35° = 18°
v² = 55² + 40² - 2 · 55 · 40 · cos 18°
v² = 3025 + 1600 - 2 · 55 · 40 · 0.951
v² = 440.6
v = √440.6
v = 20.99 ≈ 21 m/s
Answer: The wind velocity is 21 m/s.

Write an expression to evaluate the relative error in g (given that g= 2h/t^2) in terms of h,Δh,t,Δt
EleoNora [17]

An expression which can be used to evaluate the relative error in g (in terms of h, Δh, t, and Δt) is: \delta = \frac{t^2(h\;+\Delta \;h) }{h(t\;+\;\Delta t)^2} - 1

<h3>What is relative error?</h3>

Relative error can be defined as a measure of the ratio of an absolute (real) value of a measurement to an expected (theoretical) value. Also, it's independent of the magnitude of its values.

<h3>How to evaluate the relative error in g?</h3>

In order to write this expression, we would divide the absolute (real) value by the expected (theoretical) value as follows:

\delta = \frac{g(h\;+\;\Delta h,t \;+ \;\Delta t) - \;g(h,t)}{g(h,t)} \\\\\delta = \frac{g(h\;+\;\Delta h,t \;+ \;\Delta t) }{g(h,t)} - 1\\\\\delta = \frac{t^2(h\;+\Delta \;h) }{h(t\;+\;\Delta t)^2} - 1

<u>Note:</u> g = 2h/t²
