Answer:
in your mind yes but the bread is smaller than the earth thus it wouldnt turn the earth into a sandwich.
Answer:
g = 0.4 m/s²
Explanation:
Given the following data;
Height = 5 meters
Time = 5 seconds
To find the acceleration due to gravity (g) on the planet;
Mathematically, the maximum height of an object is given by the formula;
H = ½gt²
Where;
H is the height measured in meters.
g is the acceleration due to gravity.
t is time measured in seconds.
Substituting into the formula, we have;
5 = ½ * g * 5²
5 = 0.5 * g * 25
5 = 12.5 * g
g = 5/12.5
g = 0.4 m/s²
<span>It rather depends on your definition of "machine". The normal physics set of simple machines - levers, pulleys, ramps all give you increased force at the expense of reduced speed or increased speed at the expense of reduced force.
So, no - by definition a machine is an arrangement for multiplying one while paying the cost by reducing the other. You are looking at an example of the Conservation of Energy... one of the giant rules we are pretty sure cannot be violated.</span>
