Richardson pulls a toy 3.0 m across the floor by a string, applying a force of0.50 N. During the first meter, the string is para

llel to the floor. In the next two meters, the string makes an angle 0f 300 with the horizontal direction. What’s the total amount of work done by Richardson on the toy?

Answer:

Total Work done =0.65 joule

Explanation:

Work done is given Mathematically as

W=F *d

Where w=work done in joules

F=applied force

d= distance moved

The work done to move the toy accros the first meter is

W1=0.5*1

W1=0.5joule

The work done to move the toy across the next 2m at an angle of 30° is

.W2=0.5*2cos30

W2=0.5*2*0.154

W2=0.154joule

Hence total work done is

W1+W2=0.5+0.154

Total Work done =0.65 joule

What should a sailboat operator do when approaching a PWC head-on
nekit [7.7K]

<u><em>In accordance with the International Regulation for the prevention of collisions at sea</em></u><u>: </u>

<u>1.- A sailing boat has a passing preference over a motorized boat, </u><u>except when the motor boat is limited by its draft</u><u>. </u>

<u>2.- The sailboat must maintain its course and speed. </u>

<u>3.- </u><em><u>If it is evident that the PWC does not respond</u></em><u>, the sailboat must sound the warning signal, and change its course to starboard. </u>

<u>4.- </u><u><em>All actions must be taken as soon as possible</em></u><u>. </u>

<u>5.- If a sailboat is using its engine, the situation changes, and in that case, both ships must alter to starboard.</u>

Explain which is more accurate: measuring to the nearest centimeter or to the nearest half inch?
blagie [28]
Thank you for posting your question here at brainly. 

1 inch = 2.54 centimeters 
<span>Thus; 1/2 inch = 1.27 centimeters </span>
<span>Therefore; measuring to the nearest centimeter is more accurate than to the nearest half-inch.

The figure shows a jet engine suspended beneath the wing of an airplane. The weight of the engine is 14900 N and acts as shown i
joja [24]

We have that for the Question, it can be said that With respect to this axis, the magnitude of the torque due to the weight and ,the thrust is

  • TW=19740N-m
  • TT=130387.39N-m

From the question we are told

The figure shows a jet engine suspended beneath the wing of an <em>airplane</em>. The weight of the <em>engine </em>is 14900 N and acts as shown in the <em>figure</em>. In flight the engine produces a thrust of 61500 N that is parallel to the ground. The rotational axis in the <em>figure </em>is <em>perpendicular </em>to the plane of the paper. With respect to this axis, find the <em>magnitude </em>of the torque due to (a) the <em>weight </em>and (b) the <u>thrust</u>.

a)

Generally the equation for the <u>Torque </u>due to weight  is mathematically given as

TW=Engine weight*2.50*sin32\\\\TW=14900*2.50*sin32

TW=19740N-m

b)

Generally the equation for the <em>Torq</em>ue due to thrust  is mathematically given as

TT=Engine thrust*2.50*cos32\\\\TT=61500*2.50*cos32\\\\

TT=130387.39N-m
