Dos masas de 8kg es tan unidas en el extremo de una varilla de aluminio de 400mm de longitud. la varilla está sostenida en su parte media hora en círculos y solo puede soportar una tensión máxima de 800 n ¿cuál es la frecuencia máxima de revolución

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant
