Answer:
Explanation:
v = u + at
v₃ = 100 +30.0(3.00) = 190 m/s
s = vt + ½at²
y₃ = (100sin53)(3.00) + ½(30sin53)(3.00²) = 347.4 m
x₃ = (100cos53)(3.00) + ½(30cos53)(3.00²) = 261.8 m
a) v² = u² + uas
s = (v² - u²) / 2a
ymax = 347.4 + (0² - (190sin53)²) / (2(-9.80)) = 1,522 m
b) t₁ = 3.00 s
t₂ = (190sin53) / 9.80 = 15.5 s
t₃ = √(2(1522) / 9.80) = 17.6 s
t = 3.00 + 15.5 + 17.6 = 36.1 s
c) xmax = 261.8 + (190cos53)( 15.5 + 17.6) = 4,047 m
A couple things could be done such as recycling and using nonrenewable resources more efficiently.
Explanation:
Given that,
Input force on a simple machine, F = 2 N
The output force on a simple machines, F' = 4 N
The ratio of the output force to the input force of any simple machines is called its mechanical advantage. Mathematically, it is given by :
Putting the value of F and F' in above equation. We get :
m = 2
So, the mechanical advantage of the simple machines is 2. Hence, this is the required solution.
The actual mass of a 1 cm² piece of copy paper is determined as 0.0074 g.
<h3>Area of the sheet of paper in square centimeters</h3>
Area = Length x Width
Area = (11 x 2.54 cm) x (8.5 x 2.54 cm)
Area = 603.22 cm²
<h3>Actual mass of the sheet of paper</h3>
Mass = area density/area
Mass = (4.5 gcm²)/(603.22 cm²)
Mass = 0.0074 g
The complete question is below:
A sheet of 8.5 inch by 11inch paper has a mass of 4.50 grams one square centimeter , 1cm2 of that sheet of paper will have a mass closets to ____grams ( (hint use 1inch = 2.54 centimeters and area = length times)
