A block weighing 70.0 N rests on a plane inclined at 25.0° to the horizontal. A force F is applied to the object at 50.0° to the horizontal, pushing it upward on the plane. The coefficients of static and kinetic friction between the block and the plane are, respectivel...
A rifle bullet with a mass of 17.5 g traveling toward the right at 293 m/s strikes a large bag of sand and penetrates it to a depth of 23.6 cm. Determine the magnitude and direction of the friction force (assumed constant) that acts on the bullet.
D is wrong
please help me if you can. I have no values, just diagrams. the first diagram: a box is attached to a rope and pulled along a floor with the rope parallel to the floor. The second diagram: a box is attached to a rope and pulled along a floor with the rope at an angle (upwards)...
well I have 3 diagrams and I'm supposed to rank them in order of strongest normal force to weakest normal force, so I'm just not sure how to tell which is the strongest.
How can you tell which force diagrams have a strong normal force and which ones have a weak normal force?

Thank you so much! Another question, the directions say, Determine the [H3O] and [OH] of each of the following solutions. Lime Juice, pH= 1.9 Kitchen Cleaner, pOH= 4.75 Tomato Juice, pH= 4.23 How do I do this?
I think i figured it out, would the pH be .9?
