Suppose three differ people take measurements of the height of a skateboard ramp. the three measurements are 27.4 cm, 27.4 cm, and 27.5 cm. the actual height of the ramp is 30.5 cm. which of the following best describes these results?

Um vetor representa um deslocamento cujo módulo é 20 m. se v faz um ângulo de 60 graus com a horizontal, qual é o valor das componentes horizontal e vertical deste vetor?

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.
