¿Sabes cómo se realizan los viajes al espacio? ¿En qué consiste? ¿Cómo llegó el hombre a la Luna? ¿Cómo se miden estas distancias? ——————————————
Do you know how space travel is done? What does it consist of? How did man get to the moon? How are these distances measured? help me please

The volume of a gas is halved during an adiabatic compression that increases the pressure by a factor of 2.5. what is the specific heat ratio? show the math steps .

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.

Which changes would result in a decrease in the gravitational force btween two objects? check all that apply
