The ideal mechanical advantage of a lever (IMA) is given by:
Where:
Le = Effort of the arm
Lr = Resistance arm.
Therefore, we can increase the force adventage by increasing the effort arm or reducing the load arm
Answer:
a. Make the effort length longer.
Graph paper can be effectively used to measure the area of irregular objects...... because the graph consists of small units of 1 into 1 cm.. if an irregular object is kept And drawn over the graph then you can consider those 1 into 1 unit boxes for calculating the surface area. moreover find the thickness of the object then we can find the volume too
Magnitude is the word used to describe the amount of energy released by an earthquake.
Hope I helped! :D
Answer:
18 miles east; 24 mph east
Explanation:
In order to find how far east of Wilmington is the ship after 1 hour, we just need to substitute t = 1 into the formula of the position.
The equation of the position is
where t is the time. Substituting t = 1,
So, the ship is 18 miles east of Wilmington.
To find the velocity of the boat, we just need to calculate the derivative of the position, so
And by substituting t = 1, we find the velocity after 1 hour:
And the direction is east.
