Answer:
this is just a black bar, I do not understand.
Explanation:
Neither does. Their effects are <em>EQUAL.</em>
Potential energy = (MASS) x (gravity) x (HEIGHT)
You should be able to look at this formula and see that the effects of mass and height are equal. Gravitational potential energy is directly proportional to both of them.
If you want to increase the potential energy of some object, say, by 42%, you can do it either way ... either increase the object's mass by 42%, OR raise the object 42% higher than it is now. Either of those changes will have the same effect on the object's potential energy.
<span>So we want to see what is the unit of electric current. The unit of electric current is 1A or 1 Ampere and it is defined as that current which would produce a force of 10^-7 N per metre lenght between two infinite parallel conductors separated by 1 meter of lenght. </span>
Using kinematics we can find that the take-off distance is 6163 ft
Given parameters
- The initial and final speed of the plane i = 0 and v = 140 mph
To find
The measurement system allows not to have problems when working in different units, in this case we reduce the speed units
v = 140 mile / h (5280 ft / mile) (1h / 3600 s) = 205.34 ft / s
The kinematics allows to find the relationships between the position, the speed and the acceleration of a body, in this case the movement is in one dimension.
v = v₀ + a t
where v and v₀ are the final and initial velocity, respectively, at acceleration and t the time
a =
a =
a = 3.42 ft / s²
Let's use the expression
v² = v₀² + 2 a x
Where v and v₀ are the final and initial velocity, respectively, at acceleration and x the distance traveled
x =
x =
x = 6163.8 ft
Let's reduce to miles
x = 6163.8 ft (1 mile / 5280 ft)
x = 1.17 mile
In conclusion using kinematics we can find that the take-off distance is 6163 ft
