Answer:
wood
Explanation:
you can last longer with wood because you are using up gas when you drive your car that will mean that you will have to go and find gas if you run out an example like we are in the zombie apocalypse.
Answer:
a) A = 0.07129 m²
b) A / A ’= 1.77
Explanation:
In this exercise we are asked to find the area in SI units, so let's start by reducing the dimensions to SI units.
width a = 8.5 inch (2.54 cm 1 inch) (1 m / 100 cm)
a = 0.2159 m
length l = 13 inch (2.54 cm / 1 inch) (1 m / 100 cm)
l = 0.3302 m
The area of a rectangle is
A = l a
A = 0.3302 0.2159
A = 0.07129 m²
b) we have a second sheet with reduced dimensions
a ’= 3/4 a
l ’= ¾ l
Let's find the area of this glossy sheet
A ’= l’ a ’
A ’= ¾ l ¾ a
A ’= 9/16 l a
To find the factor we divide the two quantities
A / A ’= l a 16 / (9 l a
A / A ’= 1.77
X2 = 60
/ 2 / 2
x = 30
Plus or minus square root 60
Answer:
In free fall, mass is not relevant and there's no air resistance, so the acceleration the object is experimenting will be equal to the gravity exerted. If the object is falling on our planet, the value of gravity is approximately 9.81ms2 .
Answer:
1.85 m/s
102.438 m
Explanation:
From vector motion
The resultant velocity
The magnitude of speed of the speed of the boat relative to a stationary shore observer is 1.85 m/s
The distance covered is 229 m
Time = Distance / Speed
Distance = Speed of current × Time
Distance = 0.756×135.5 = 102.438 m
The boat will be 102.438 m from the initial position is the boat when it reaches the opposite shore
