How do you find the normal force if the given are mass and tension?

First . . . look at the drawing, and keep looking until you understand how
the normal force is related to the tension.
Here's a hint that may or may not help: Remember that if nothing is moving,
then the sum of all the forces at any point is zero. And whatever you do,
don't forget about gravity, and its effect on the mass..

How do you find the normal force of a 25 kg object being pulled by a rope at a tension of 120 N along a frictionless surface at an angle of 30 degrees?
I could be totally wrong but I believe you must take into account the forces on the object in the vertical direction. In this case, the object is being pulled by a rope with a tension of 120 N. The vertical force would therefore be 120 sin(30) Normally W = [F normal] with no vertical force. However, since there is a vertical force: W = [F normal] + [120 sin (30)] (25 kg X 9.8 m/s2) = [F normal] + [120 sin (30)] 245 N - 60 N = [F normal] 185 N = [F normal] I apologize if this is incorrect as I haven't been in a physics class in over 4 years. Good luck!
How can you find force when given distance and speed?
You cannot. Force is mass times acceleration. You have neither.
How do you find force given weight and work?
You cannot. You do not have the necessary information.
How can you find force when given time velocity and mass?
Force equals mass times acceleration.
How can you find force when mass and velocity are given?
You cannot. Force = Mass*Acceleration or Mass*Rate of change of Velocity.
How do you find the normal force and force of friction of an object on a incline?
To find the normal force on an object on an incline, you can use the component of the object's weight perpendicular to the incline. The force of friction can be calculated using the coefficient of friction between the object and the incline, along with the normal force.
If A 100 kg object is pulled vertically upward 5.0 m by a rope with an acceleration of 1.0 ms2 Find the work done by the tension force in the rope?
The work done by the tension force is calculated as the product of the force exerted by the tension and the distance over which it acts. The force exerted by the tension is given by the mass times the acceleration plus the force due to gravity. Work = force * distance = (mass * acceleration + mass * gravity) * distance. Plug in the values to find the work done by the tension force.

What formula do you used to find the normal force?
The formula to find the normal force on an object on a flat surface is: Normal force = Weight of the object * cos(theta), where theta is the angle between the object's weight and the surface. This formula takes into account the component of the weight that acts perpendicular to the surface.
How do you find pressure given force and area?
P = F/A, so Area = Force/Pressure
How can you find force when given distance and speed?
You cannot. Force is mass times acceleration. You have neither.
How do you find output force if you are only given efficiency and work?
You can find the output force by dividing the work done by the input force by the efficiency. This formula is: Output Force = Work / (Input Force * Efficiency).
How do you find force given weight and work?
You cannot. You do not have the necessary information.
How can you find force when given time velocity and mass?
Force equals mass times acceleration.
How can you find force when mass and velocity are given?
You cannot. Force = Mass*Acceleration or Mass*Rate of change of Velocity.
How do i find a Normal reaction force on an angle?
To find the normal reaction force acting on an object at an angle, you can resolve the forces into horizontal and vertical components. The normal reaction force will be the vertical component of the force acting perpendicular to the surface. You can use trigonometry to calculate this component by using the angle at which the object is situated.
Where would you expect to find tension?
Normal fault
