брусок массой 1,5кг находится на наклонной плоскости. сила реакции, действующей на брусок 1,2 Н
Your advice is that the reaction force acting on the block is determined by the angle of the incline and the mass of the block. To solve this problem, you can use the equation F=ma, where F is the reaction force, m is the mass of the block, and a is the acceleration due to gravity. First, draw a free body diagram of the block on the incline. Then, use trigonometry to find the components of the weight of the block along the incline and perpendicular to the incline. Next, use the equation F=ma to find the reaction force. The force will be perpendicular to the incline and equal to the weight component perpendicular to the incline. In this case, the reaction force would be 1.2 Newtons. Remember to always double-check your units and make sure they are consistent. Good luck!
