Answer:
The resultant of two forces of 7N and 3N acting at a right angle to one another is √58 N.
Step-by-step explanation:
Let the magnitude of the force of 7N be denoted as “F₁” on the x-axis and the magnitude of the force of 3N be denoted as “F₂” on the y-axis.
We are given that the two forces make an angle of 90° to one another as shown in the figure attached below.
Also, in the figure, we can see that the resultant force is denoted as “F”.
Now,
The magnitude of the resultant force can be calculated by using the Pythagoras theorem,
∴ F = √[F₁² + F₂²]
⇒ F = √[7² + 3²]
⇒ F = √[49 + 9]
⇒ F = √[58] N
Eric is incorrect because since the numbers he rounded 28 and 48 to are greater than 28 and 48 the answer to 28*48 will be less than the answer to 30*50 was.
30*50 = 1500
28*48 = 1344
Hope that helps!! :D
Yea since because I have no clue
Each sides are equal so the answer 400 cubic in
