Can ?i have the answer please

Consider the Figure 3.25 . What is the sine of the angle 35? Remember to write it to two decimal places.

In the previous question you considered Figure 3.25 and determined the sine of the angle shown in the diagram. Which of the forces can this be used to determine?

a. F1

b. F2

C. NONE OF THESE FORCES WE NEED MORE INFORMATION

D. ALL OF THE FORCES CAN BE DETERMINED BY THE SINE OF THE ANGLE

From the information in the previous two questions, what is the value of the force that you calculated using the sine of the angle in Figure 3.25?

True/Flse Consider problem 3.24 in your text. The flea exerts a downward force and jumps. This force is necessary to overcome the weight of the flea.

Based on the question 3.24 . What is the net upward force on the flea. For really small numbers (eg 0.886×10-6), you need to write it in the following form 0.89E-6. Choose up to be the positive direction.

Determine the resultant force on the flea based on its upward force and the force on its face parallel to the ground. Refer to the questions 3.24 for force of the wind on the face of the flea,
