A150-newton force, applied to a wooden crate at an angle of 30° above the horizontal, causesthe crate to travel at constant velocity across a horizontal wooden floor.
1. calculate the magnitude of the normal force exerted by the floor on the crate. [show all work, including the equation and substitution with units.]2. determine the magnitude of the frictional force acting on the crate.3. calculate the magnitude of the horizontal component of the 150-newton force. [show all work, including the equation and substitution with units.]

Ineed the answer to question 1 , i’m desperate

If a substance is in the gas phase, which of qualities of the gas will stay constant? a: volume b: mass c: shape d: position of particles

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
