Responder:

0.6 m

Explicación:

Responder:

0,15 m

Explicación:

Paso uno:

dado

Fuerza F = 250N

diámetro d1- 16 cm am = 0.16 m

A1 = πd1 ^ 2/4 = 3.142 * 0.16 ^ 2/4

= 0.02 m ^ 2

Carga L = 3500N

A2 =?

Segundo paso:

sabemos que la presión aplicada a un extremo para levantar una carga en el otro extremo se expresa matemáticamente como

F1 / A1 = F2 / A

sustituir

250 / 0.2 = 3500 / A

cruzar multiplicar

A2 = 0.02 * 3500/250

A2 = 70.3 / 250

A2 = 0.28

sabemos que área = πd ^ 2/4

0.28 = πd2 ^ 2/4

0.28 = 3.142 * d2 ^ 2/4

0.28 * 4 / 3.142 = d2 ^ 2

0.36 = d ^ 2

d = √0.36

d = 0.6 m

el diámetro debe ser de 0.6 m

What is the dot product of a= -2i - 5j and b=i -4j
Dafna1 [17]
I.i = j.j = 1
i.j = j.i = 0

(-2i - 5j)(i -4j)
= (-2i).i + (-2i).(-4j) + (-5j).i + (-5j).(-4j)
= -2 + 0 + 0 + 20 = 18

During a storm, a tree limb breaks off and comes to rest across a barbed wire fence at a point that is not in the middle between
Whitepunk [10]

Answer:

a. 12.12°

b. 412.04 N

Explanation:

Along vertical axis, the equation can be written as

T_1 sin14 + T_2sinA = mg

T_2sinA = mg - T_1sin12.5           ....................... (a)

Along horizontal axis, the equation can be written as

T_2×cosA = T_1×cos12.5    ......................... (b)

(a)/(b) given us

Tan A = (mg - T_1sin12.5) / T_1 cos12.5

 = (176 - 413sin12.5) / 413×cos12.5

A = 12.12 °

(b) T2 cosA = T1 cos12.5

T2 = 413cos12.5/cos12.12

= 412.04 N

A football is thrown due north across a 40 meter river and it takes 2 seconds to cover that distance.
Alexxx [7]

Answer:

I. Speed = 20m/s

II. Velocity = 20m/s due North.

Explanation:

<u>Given the following data;</u>

Distance = 40m

Time = 2secs

To find the speed;

Mathematically, speed is given by the formula;

Speed = \frac{distance}{time}

Substituting into the equation, we have;

Speed = \frac{40}{2}

<em>Speed = 20m/s.</em>

In physics, we use the same formula for calculating speed and velocity. The only difference is that speed is a scalar quantity and as such has magnitude but no direction while velocity is a vector quantity and as such it has both magnitude and direction.

Velocity = \frac{distance}{time}

<em>Therefore, the velocity is 20m/s due North</em>.

3.Three resistors of 25.0Ω, 30.0Ω, and 40.0Ω are in a series circuit with a 6.0-volt battery. What is the current in the circuit
AURORKA [14]

Answer:

Current = 0.063 Amperes

Explanation:

Let the three resistors be R1, R2, and R3 respectively.

Given the following data;

R1 = 25.0Ω,

R2 = 30.0Ω

R3 = 40.0Ω

Voltage = 6 Volts

First of all, we would determine the equivalent or total resistance;

Total resistance (in series) = R1 + R2 + R3

Total resistance = 25.0Ω + 30.0Ω + 40.0Ω

Total resistance = 95 Ω

Next, we find the current flowing through the circuit;

Voltage = current * resistance

Substituting into the formula, we have;

6 = current * 95

Current = 6/95

Current = 0.063 Amperes
