Answer:
6000 cm<em>²</em>
Explanation:
let width of rectangle = 
Using Pythagorean theorem,
+<em> 50² = 130²</em>
<em />
<em> = 130² - 50² </em>
<em />
<em> = 14400</em>
<em />
<em>= 120 cm</em>
area of rectangle <em>=</em> length x width
<em>=</em> <em>120 x 50</em>
<em>= 6000 cm²</em>
Do you mean ‘Does a larger object have less attraction than a smaller object?’ If so, then the answer is objects with a larger mass exert more attraction while objects with a smaller mass have less attraction.
Answer:
v = 31.3 m / s
Explanation:
The law of the conservation of stable energy that if there are no frictional forces mechanical energy is conserved throughout the point.
Let's look for mechanical energy at two points, the highest where the body is at rest and the lowest where at the bottom of the plane
Highest point
Em₀ = U = m g y
Lowest point
= K = ½ m v²
As there is no friction, mechanical energy is conserved
Em₀ =
m g y = ½ m v²
v = √ 2 g y
Where we can use trigonometry to find and
sin 30 = y / L
y = L sin 30
Let's replace
v = RA (2 g L sin 30)
Let's calculate
v = RA (2 9.8 100.0 sin30)
v = 31.3 m / s
