Find the perimeter of the rectangle if each block represents one foot(show your calculation)

Answers

Answer 1

Answer:
I'm pretty sure that the "block" of which you speak is one in a pattern
of them that covers the drawing you have of the rectangle, and now
I need to explain something to you:

The REASON for printing that drawing next to the question that you
partially copied is that the drawing has information that's needed to
answer the question with, and rather than repeat all that information
in the question, it just says "LOOK AT THE DRAWING !"

In fact, the whole point of the question may not be just to remind you of
what "perimeter" means. It's more likely that the purpose of this problem
is to make you pick the information you need off of a drawing.

Either way, if you'll kind of "read between the lines" of the part of the
question that you DID copy, it should be pretty obvious to you that nobody's
going nowhere in the direction of a solution without SEEing the drawing.

So my bottom-line conclusion regarding a solution for this problem is:
Not possible with the given information.

Please help me A person launches a home-built model rocket straight upinto the air at y = 0 from rest at time t = 0 . (The positive y-direction is upwards). The fuel burns out at t = t0. The position of the rocket is given by

with a0 and g are positive. Find the y-components of the velocity and acceleration of the rocket as a function of time. Graph ay vs t for 0 < t < t0.

Answers

-- We know that the y-component of acceleration is the derivative of the
y-component of velocity.

-- We know that the y-component of velocity is the derivative of the
y-component of position.

-- We're given the y-component of position as a function of time.

So, finding the velocity and acceleration is simply a matter of differentiating
the position function ... twice.

Now, the position function may look big and ugly in the picture. But with the
exception of 't' , everything else in the formula is constants, so we don't even
need any fancy processes of differentiation. The toughest part of this is going
to be trying to write it out, given the text-formatting capabilities of the wonderful
envelope-pushing website we're working on here.

From the picture . . . . . y (t) = (1/2) (a₀ - g) t² - (a₀ / 30t₀⁴ ) t⁶

First derivative . . . y' (t) = (a₀ - g) t - 6 (a₀ / 30t₀⁴ ) t⁵ = (a₀ - g) t - (a₀ / 5t₀⁴ ) t⁵

There's your velocity . . . /\ .

Second derivative . . . y'' (t) = (a₀ - g) - 5 (a₀ / 5t₀⁴ ) t⁴ = (a₀ - g) - (a₀ /t₀⁴ ) t⁴

and there's your acceleration . . . /\ .
That's the one you're supposed to graph.

a₀ is the acceleration due to the model rocket engine thrust
combined with the mass of the model rocket
'g' is the acceleration of gravity ... 9.8 m/s² or 32.2 ft/sec²
t₀ is how long the model rocket engine burns

Pick, or look up, some reasonable figures for a₀ and t₀
and you're in business.

The big name in model rocketry is Estes. Their website will give you
all the real numbers for thrust and burn-time of their engines, if you
want to follow it that far.

Density equals:
weight/area
weight/volume
mass/weight
mass/volume

Answers

Density can be determined by themass of an object and how much it takes up space (volume). Or density is equal to mass over volume. It is represented bythe formula D = M/V where D is the density in kg/m^3 or lb/ft^3, M is the massin kg or lb and V is the volume in m^3 or ft^3.

For example, you are given the mass of anobject of 40.5kg and a volume of 15m^3. Find its density.

D = M/V
D = (40.5 kg)/ (15 m^3)
D = 27/10 or2.7 kg/m^3

What taskmasters is bassically saying is Density is Mass Divided by Volume.

Answers

Answer:

The correct answer is option A, An antacid neutralizes excess hydrogen ions.

Explanation:

Antacid neutralizes the acid in the stomach. These are bases/ alkali's. The reaction between an acid and a base in known as neutralization thereby reducing burning sensations produced by the acid.

The antacid when reaches the stomach form gel like composition that lie on the top of food item in the stomach and prevent the oesophagus from the irritation caused by the acid.

What does viscosity describe? Question 4 options: A. a fluid's resistance to being heated
B. the rate of evaporation of a fluid
C. how much energy it takes to warm a fluid
D. the density of a fluid
E. a fluid's resistance to flowing

Answers

Answer:

E. a fluid's resistance to flowing

Explanation:

Viscosity, also known as "thickness" is a rheological property that describes a fluid's resistance to flowing, fluids of low viscosity, like water, flow more easily while high viscosity fluids, like mud, are harder to move through. It is an important property because it determines the energy required to make a certain fluid flow.

D. the density of a fluid
