Please help, I need it now! (data, resolution, response)
1.Calculate the force we need to make to lift a weight of 350N if the force arm measures 30m and the resistance arm measures 7m
2. Calculate the weight I can lift with a force of 3400N, if the d2 is 2.5m and the d1 is 11.2m.
3. Calculate the length of the force arm if I have to lift a weight of 350N with a force of 23N and the resistance arm measures 2.3m.
4. Calculate how much the resistance arm should measure, if we make a force of 2340N to lift a weight of 240N if the force arm measures 12.4dm.
5. Calculate the mass I can lift, if I make a 340N force with a lever 23.4cm of force and 12.4cm of resistance.

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
