Three forces with magnitudes 75 pounds110 pounds and 30 pounds act on an object whats the magnitude?

That all depends on the direction of each force.
Examples:
If all 3 forces are in the same direction, the net force on the object is 215 pounds in that same direction.
If the 30 and the 75 both point left and the 110 points right, the net force is 5 pounds to the right.
If the 30 points west, the 75 points north, and the 110 points south, the net force is 46 pounds toward roughly southwest.

What does magnitude refer to when doing mathematics?
Magnitude refers to the size of a mathematical object. The greater an object's volume, area, or length, the greater its magnitude. The magnitude of a number is referred to as its "absolute value."
What is lemis theorem?
from ramanjit singhIts Lamis Theorom.In statics, Lamis theorem is an equation relating the magnitudes of three coplanar, concurrent and non-collinearforces, which keeps an object in static equilibrium, with the angles directly opposite to the corresponding forces. According to the theorem,where A, B and C are the magnitudes of three coplanar, concurrent and non-collinear forces, which keep the object in static equilibrium, andα, β and γare the angles directly opposite to the forces A, Band C respectively.Do you like the answer?

What happens if an object covers equal distances in equal periods of time?
Then you can say that the object's speed and the magnitude of its velocity are constant, and the magnitude of its acceleration is zero.
Two forces are exerted on an object A 39 N force acts at 220degrees and a 55 N force acts at 315degrees What are the magnitude and direction of the equilibrant?
you fail in grade 11 physics
What is perpendicular forces?
Perpendicular Force is the forces that acts at right angle to the object.
If 2 force act on the object in the same or opposite directions what willbe the net force of the object in 2 cases?
There is no net force OF the object. If the forces act in the same direction, the net force is magnitude of the net force is the sum of the forces and acts in the same direction. If the forces act in opposite directions, the magnitude of the net force will be the difference between their magnitudes and it will act in the direction of the larger of the two forces.
How do unbalanced forces affect an objects velocity?
When the forces on an object are unbalanced, the object undergoes acceleration. Its direction is the direction of the net effective force, and its magnitude is the magnitude of the net effective force divided by the object's mass.
What do you call the the quantity that describes a moving object using magnitudes only?
The quantities that describes about only magnitude is called SCALAR quantity
What is An arrow drawn to represent the direction and magnitude of an object is referred to as?
There is no such thing as the direction or magnitude of an object. The direction and magnitude of its speed, acceleration, or momemtum, or of the forces on it, are represented by vectors.
Is a magnitude -3 star brighter or dimmer than a magnitude of a 0 star?
When it comes to objects in the sky, lower-number magnitudes are brighter than higher-number magnitudes. (-3) is a lower number than zero, so an object with a magnitude of -3 is brighter than an object of zero. The [mean apparent visual] magnitude of the sun is -26.7. For the full moon it's -12.7, and for the maximumn brightness of Mars it's -2.9 .
Is mass the magnitude of the force due to gravity on an object?
No mass is not the magnitude of the force due to gravity on an object. Mass is the stuff of which the object is composed. The magnitude of the gravitational forces between the object and Earth ... or whatever planet the object happens to be on ... is the object's "weight".
How much does the brightest of a star change with each change in magnitude of one?
The magnitude scale is calibrated such that a difference of 5 magnitudes is equal to a 100x difference in brightness. Note also that the lower the value for magnitude, the brighter the object is. If object A has a magnitude of 0 and object B has a magnitude of -5, then object B is 100 times as bright as object A. The fifth root of 100 is 2.512 (to 4 significant figures), therefore a difference in magnitude of 1 is equal to a 2.512x difference in brightness.
What is the magnitude of the resultant force in Newtons acting on an object that has 2 forces acting in same direction having magnitudes of 15 N and 25 N and a 3rd force acting perpendicular at 30 N?
Add forces 1 and 2 = 40N Magnitude of resultant = root[402+302] = 50N [Also, this is at an angle of 36.9 degrees to the 30N force]
What is the net force when a pair of balanced forces acts on an object?
if forces are balanced net force = 0 and the object has no action, it does not move
When the cardboard is at rest how do the magnitudes and directions of the pair of force acting on it compare?
For any object to be at rest the Forces acting on it must be EQUAL in magnitude and OPPOSITE in direction.
What is newton second laws application?
Newton's second law was used to analyze a variety of physical situations. The idea was that if any given physical situation is analyzed in terms of the individual forces which are acting upon an object, then those individual forces must add up as vectors to the net force. Furthermore, the net force must be equal to the mass times the acceleration. Subsequently, the acceleration of an object can be found if the mass of the object and the magnitudes and directions of each individual force are known. And the magnitude of any individual force can be determined if the mass of the object, the acceleration of the object, and the magnitude of the other individual forces are known. The process of analyzing such physical situations in order to determine unknown information is dependent upon the ability to represent the physical situation by means of a free-body diagram. A free-body diagram is a vector diagram which depicts the relative magnitude and direction of all the individual forces which are acting upon the object.

In which circumstance will tow forces acting on an object be balanced?
When their magnitudes are equal and their directions are separated by 180 degrees ... i.e. they're opposite.
