To obtain an acceleration northward is necessary than the west component of the first cable and the east component of the second cable be equal, otherwise the barge will head northwest or northeast.
So for the first cable the component to west is:
Fw = F1 * cos (30Âş) = 80*cos(30Âş)
And for the second cable the component to east is:
Fe = F2 * cos (20Âş) = F2*cos(20Âş)
Then to get a movement northward we need than Fw = Fe, so:
80*cos(30Âş) = F2*cos(20Âş)
F2 = 80*cos(30Âş)/cos(20Âş)
F2 = 73.73 N So the magnitude of the east cable should be 73.73 Newtons
The plasma membrane of a cell is a group of lipids and proteins that forms the boundary between a cell's contents and the outside of the cell.
Taking into account the definition of speed, the average speed of the Olympic sprinter is 10 
<em>.</em>
<h3>What is speed</h3>
Speed is a physical quantity that expresses the relationship between the space traveled by an object and the time used for it.
In other words, speed can be defined as the amount of space traveled per unit of time with which a body moves and can be calculated using the expression:
<h3>Average speed of the sprinter</h3>
In this case, you know:
- distance traveled= 100 meters
- time= 10 seconds
Replacing these values in the speed definition:
Solving:
<u><em>speed= 10 </em></u>
In summary, the average speed of the Olympic sprinter is 10 <em>.</em>

A 2.0 kilogramme chunk of heated copper is cooled by being lowered into 5.0 kg of water. Water goes from 30 degrees Celsius to 52 degrees Celsius in only a few hours. determine the copper's temperature before submerging it in water. In this case, the water's temperature is 24 degrees, and when we plug this number into equation 2 for water, we get the copper's temperature as 100 (0.387) (200-x) = 400 (4.187). ( x-20)
100 (0.387) (200-x) = 400 (4.187) ( 24-20)
: to give (something) over to the power or control of another : surrender The troops would not yield the fort to the enemy. 2 : to give in He yielded to temptation. 3 : to produce as a natural product These trees yield fruit.
Solving it yields x = 26.89 degrees, indicating that the temperature of ;copper is 26.89 degrees.
