Answer:
p = 200Pa
Explanation:
From its definition, the pressure depends on the force exerted on the floor by the cabinet, and the perpendicular area in which it is applied. This is expressed in the formula:
Since the force the cabinet exerts on the floor is its weight, we can use the given values to calculate the pressure exerted on the floor:
In words, the pressure the cabinet exerts on the floor is 200Pa.
<span>While a utility patent protects the way an invention is used and works, a design patent protects the way it looks.
Patent is a grant from federal government conferring the rights to exclude others from making, using or selling an invention.
There are three types of patents: Utility, design and plant. Only the inventor or inventors together can apply for a patent.</span>
L = length of the incline = 75 m
θ = angle of incline = 22 deg
h = height of skier at the top of incline = L Sinθ = (75) Sin22 = 28.1 m
μ = Coefficient of friction = 0.090
N = normal force by the surface of incline
mg Cosθ = Component of weight of skier normal to the surface of incline opposite to normal force N
normal force "N" balances the component of weight opposite to it hence we get
N = mg Cosθ
frictional force acting on the skier is given as
f = μN
f = μmg Cosθ
v = speed of skier at the bottom of incline
Using conservation of energy
potential energy at the top of incline = kinetic energy at the bottom + work done by frictional force
mgh = f L + (0.5) m v²
mgh = μmg Cosθ L + (0.5) m v²
gh = μg Cosθ L + (0.5) v²
(9.8 x 28.1) = (0.09 x 9.8 x 75) Cos22 + (0.5) v²
v = 20.7 m/s
A. physical change
Look at the way water freezes and changes to ice<span>. The matter is still going to be the same. its just the physical property that changed.
<u>PHYSICAL= TEMPORARY</u>
<u>CHEMICAL= PERMANENT</u></span>
Answer:
the x and y values
Explanation:
because on the table the x is the input and y is the output
