D. 7.06N, 10.98N​

Answer 1

Answer:

option b

Explanation:

Answer 2

The force component will be A) -9.11N and 11.97N.

step-by-step Explanation

In material science, force is an impact that can change the movement of an object. A force can make an item with mass change its speed (for example moving from a condition of rest), i.e., to accelerate. Force can likewise be depicted naturally as a push or a draw.  Force has both size and bearing, making it a vector amount. It is estimated in the SI unit of newton (N).

A power f has a magnitude of 300 Newton and makes a point of 300 degrees with the positive x pivot. What is the part of the power along the x-axis; fx and along the y-axis; fy?

Given

The greatness of the force, F=300N

Point θ=300°

The above circumstance can be drawn as follows

Hence the part of power along the x-axis is

Fx=Fcos(360−θ)=Fcos(360-300)=Fcos(60)

( ∵cos is positive in forwarding quadrant)

Fx=300×12=150N

The part of power along the x-hub is

Fy=Fsin(360−θ)=Fsin(360-300)=F(−sin(60))

[ sin(360−θ)=−sinθ this is on the grounds that (360−θ) lies in the forward quadrant where sin is negative as per ASTC rule.]

Fy=300×(−0.866)=−259.8N

Thus, the force component will be A) -9.11N and 11.97N.
