Answer:

The answer is SYMBOL B.

Explanation:

The correct schematic is the one that shows three groups of long and short lines. A schematic with one long and one short (one group) would be a one cell; a schematic with a long, a short, a long, a short (two group), would be a two cell; and a schematic with a long, a short, a long, a short, a long and a short (three group), would be a three cell- hence why the answer is symbol B.

The three cables are used to support the 40-kg flowerpot. Determine the force developed in each cable for equilibrium.

BabaBlast [244]

The image of the 3 cables used to support the flower pot is not given so i have attached it.

Answer:

F_ab = 523.2 N

F_ac = 392.4 N

F_ad ≈ 762.7 N

Explanation:

First of all, let's Calculate the sum of forces around the z-axis.

But before then, we need to resolve the distances along the 3 axis to get;

1.5/√(1.5² + 2² + 1.5²) = 0.5145

Thus;

ΣF_z = 0;

(F_ad × 0.5145) - (40 × 9.81) = 0

Where;

(40 × 9.81) is the weight of the flower pot.

F_ad is the force in cable AD

Thus;

0.5145F_ad - 392.4 = 0

F_ad = 392.4/0.5145

F_ad ≈ 762.7 N

Now, let's do the same for the x-axis;

ΣF_z = 0;

Since x = 1.5, just like z was the same 1.5, we will adopt same resolved distance.

F_ac - F_ad(0.5145) = 0

Where F_ac is force in cable AC

F_ac = 762.7 × 0.5145

F_ac = 392.4 N

Lastly, for the y-axis;

ΣF_y = 0;

y is 2 and so, we need to recalculate the resolved distance.

F_ab - F_ad(2/√(1.5² + 2² + 1.5²)) = 0

Where F_ab is the force in cable AB

F_ab = 762.7 × 0.686

F_ab = 523.2 N

within what force will acar hit a tree if the car has a mass of 3,000 kg and it is accelerating at a rate of 2 m/s/s

alexdok [17]

Use the formula. Plug in known values, so you get f = 3000*2 and get 6000N as a result.

A wave with a greater amplitude will transfer . . . . \

Orlov [11]

Answer:

More energy

Explanation:

The amount of energy carried by a wave is related to the amplitude of the wave itself. In particular, the amount of energy carried by the wave is proportional to the square of the amplitude of the wave:

$E \propto A^2$

where

E is the energy

A is the amplitude

This means, for instance, that if the amplitude of a wave is doubled, the energy it carries increases by a factor 4.

an open rectangular tank 1.0 meter wide and 2.0 meter long contains gasoline to a depth of 1.5 meters. if the height of the tank

Alekssandra [29.7K]

The maximum horizontal acceleration is solved to be 4.91 m/s^2

<u />

<h3>What is acceleration?</h3>

This is a term in physics that refers to change in velocity with time. Acceleration can be positive or negative or zero,

<u />

<u>Given data</u>

open rectangular tank

width = 1.0 m

length = 2.0 m

gasoline depth level = 1.5 m

height of the tank = 2.0 m

<h3>How to solve for maximum horizontal acceleration</h3>

lets represent the volume with x, y, and z such that z corresponds to height, y corresponds to wide or width, and x corresponds to length.

dz / dy = - ay / ( g + az )

where

ay = acceleration in the y direction

az = acceleration in the z direction which is equal to zero

g = acceleration due to gravity

plugging in az = 0

dz / dy = - ay / ( g )

ay = - ( dz / dy ) * g

to prevent spilling

dz / dy = - ( 1.5 - 1 ) / 1

dz / dy = - 0.5

ay = - ( - 0.5 ) * 9.81

ay = 4.91 meters per second square

Hence the maximum horizontal acceleration is solved to be 4.91 m/s^2
