Blocks A and B each have a mass m. Determine the largest horizontal force P which can be applied to B so that A will not move re

slava [35]

Answer:

The answer is "15 N".

Explanation:

Please find the complete question in the attached file.

In frame B:

For just slipping:

$\to \frac{P}{2} \cos \theta =mg \sin \theta\\\\\to P=2 mg \tan \theta \\\\$

$=2 \times 1 \times g \times \tan 37^{\circ}\\\\ =2 \times 10 \times \frac{3}{4}\\\\ =15 \ N$

Compute the area and circumference of a circle given the radius r if the radius is greater than or equal to 1.0; otherwise, you

Maslowich

In this question we shall present the algorithm in pseudocode, whose structure is now summarized:

1) Inputs.

2) Algorithms.

3) Outputs.

Please notice that While-cycles consider the requirement of using the algorithm as many times as user wants.

Name: Area-or-Circunference

CHAR - decide

REAL - radius, circumference, area

Say "Do you want to calculate? [Y] - Yes/[N] - No";

Write decide;

While (decide != 'Y' and decide != 'y' and decide != 'N' and decide != 'n'):

Say "Invalid option. Do you want to calculate? [Y] - Yes/[N] - No";

Write decide;

end-While

While (decide = 'Y' or decide = 'y'):

Say "Please indicate a radius";

While (radius < 0):

Say "Radius must be equal or greater than 0. Please indicate a

radius";

Write radius;

end-While

If (radius < 1):

circumference = 2*3.14*radius;

Say "The circumference has a value of %circumference length units";

Else:

circumference = 2*3.14*radius;

area = 3.14*radius*radius;

Say "The circumference has a value of %circumference length units

and the area has a value of %area square units";

end-If

Say "Do you want to calculate? [Y] - Yes/[N] - No";

Write decide;

While (decide != 'Y' and decide != 'y' and decide != 'N' and decide !=

'n'):

Say "Invalid option. Do you want to calculate? [Y] - Yes/[N] - No";

Write decide;

end-While

If (decide = 'N' or decide = 'n'):

Say "Good luck";

end-If

evablogger [386]

Answer:

The cult of personality that surrounded Joseph Stalin in the Soviet Union led soviet citizens to believe that there was undisputed support for Stalin both among the government and the common people. In turn, this fueled self-censorship and made political change harder. This cult of personality was achieved through propaganda and censorship, as the Communist Party had control of all mass media. This desire to make himself a "god-like" figure was also an attempt to increase acceptance of communism among the people and to boost morale.

KVL holds for the supermesh, so we can write a KVL equation to generate the second equation we need to solve for the two unknown

kaheart [24]

Answer:

The values of i_x,i_y and i_z as 25 mA, -25 mA and 15 mA while that of V_Δ is -25 V

Explanation:

As the complete question is not given the complete question is found online and is attached herewith.

By applying KCL at node 1

$i_x+50mA=i_y\\i_x-i_y=0.05A$

Also

$V_{\Delta}=1K*i_y$

Now applying KVL on loop 1 as indicated in the attached figure

$1K*i_y+5K(i_y-i_z)+3K*i_x=0\\3i_x+6 i_y-5i_z=0$

Similarly for loop 2

$2V_{\Delta}+5K(i_z-i_y)=0\\2*1K*i_y+5K(i_z-i_y)=0\\2K*i_y+5K(i_z-i_y)=0\\3i_y-5i_z=0$

So the system of equations become

$i_x-i_y+0i_z=0.05\\3i_x+6i_y-5i_z=0\\0i_x-3i_y+5i_z=0$

Solving these give the values of i_x,i_y and i_z as 25 mA, -25 mA and 15 mA. Also the value of voltage is given as

$V_{\Delta}=1K*i_y\\V_{\Delta}=1K*-25 mA\\V_{\Delta}=-25 V$

The values of i_x,i_y and i_z as 25 mA, -25 mA and 15 mA while that of V_Δ is -25 V

Orbit is to _____ as altitude is to _____.

lubasha [3.4K]

Answer:

What is the minimum altitude for orbit?

Technically, objects in low-Earth orbit are at an altitude of between 160 to 2,000 km (99 to 1200 mi) above the Earth's surface. Any object below this altitude will being to suffer from orbital decay and will rapidly descend into the atmosphere, either burning up or crashing on the surface.

Explanation:

orbital-mechanics orbit low-earth-orbit altitude. The altitude of a satellite is the distance between the Earth's surface and the satellite, but the Earth itself is not spherical. At the equator the Earth's radius is 21 km more than at the poles, and in fact the shape of the Earth is not even a perfect oblate spheroid.A Japan Aerospace Exploration Agency (JAXA) satellite has been certified by Guiness World Records as setting a new altitude orbit record. However, while most satellites orbit high above the Earth, the JAXA satellite Tsubame was recognized for achieving the lowest altitude, of only 167.4 kilometers.
