A ramp leading to the freeway overpass is 210 feet long and rises 31 feet. what is the measure of the angle formed between the ramp and the freeway?

A particular series circuit consists of a battery and three resistors of different resistances. The resistors are placed in the series circuit so that the current flows through the resistor with the smallest resistance first, and flows through the

Explain what surface tension is.

A helium-filled balloon is launched when the temperature at ground level is 27.8°c and the barometer reads 752 mmhg. if the balloon's volume at launch is 9.47 * 10^{4} 4 l, what is the volume in liters at a height of 36 km, where the pressure is 73.

Consider the moment when the spring is at its maximum compression. At that moment, the kinetic energy, the gravitational potential energy, and the elastic potential energy are, respectively, a - zero, at a maximum, and at a maximum b - at a maximum,

Ari, a young patient who is regularly treated by a psychiatrist, feels compelled to carry out repetitive tasks the same way very frequently. If Ari does not conduct these tasks with extreme precision, he can feel extremely nervous and uncomfortable.
