- Q1What force is described as the attraction between a sample of matter and all other matter in the universe?Weak nuclear forceGravitational forceElectromagnetic forceStrong nuclear force120s112.39.c.5.a
- Q2A student discovers a comet heading toward the Sun. The student records the initial distance from the Sun as ‘d’ while recording the initial mass of the comet as ‘m’ which resulted in a gravitational force of ‘F’. Further observation of the comet shows that as it reaches a position d/2 , the mass of the comet has been reduced to m/3 . According to the above information, which expression best represents the value of the gravitational force at d/2 ?9F/2F/32F/34F/3120s112.39.c.5.b
- Q3Astronomers use the gravitational wobble of a star to indicate the presence of planets outside our solar system. Astronomers specifically look for planets in the habitable zone of 1.6 X 10 ^11 m away from the star. Calculate the mass of a planet that exerts a 1.5 X 10 ^13 N force on a 5.4 X 10^30kg star.1.30 X 10 ^45 kg1.07 X 10 ^15 kg6.67 X 10 ^3 kg1.00 X 10^17 kg120s112.39.c.5.b
- Q4Using the gravitational force of a satellite to deflect an asteroid from colliding with Earth is not feasible because —the gravitational force only exists between large objectsthe gravitational force of the asteroid is greater than that of the satellitefriction in space will resist gravitational force between objectsthe magnitude of the gravitational force is small120s112.39.c.5.b
- Q5The mass of a newly discovered planet is 4.4 X 10^25 kg. What must the radius of the planet be to have the same acceleration due to gravity as Earth?There is not enough information to determine the acceleration due to gravity.1.73 X 10 ^7 m1.70 X 10^8 m2.99 X 10^14 m120s112.39.c.5.b
- Q6A student attempts to measure the maximum possible distance two masses can be away from one another and still register on the force-meter available. The masses are 2 kg and 7 kg respectively while the force-meter is capable of detecting a force as low as 0.000002 N. What is the greatest distance the masses can be apart and still register on the force-meter?7,000,000 m2.16 X 10 ^-2 m2650 m4.67 X 10^-4 m120s112.39.c.5.b
- Q7What is the gravitational force between two identical 5000 kg asteroids whose centers of mass are separated by 100 m?49,000 N8300 N1.67 X 10^-7 N1.67 X 10 ^-4 N120s112.39.c.5.b
- Q8A probe is sent to a planet of unknown mass. The probe has several instruments for measuring and sending information back to Earth. The probe gathered the information below when analyzing the gravitational force the planet exerts. A computer glitch prevents the probe from sending the units of measurement for the independent variable. Refer to the above information and graph. A student has been tasked with interpreting the data. What units should be used to describe the independent variable?kgNm^2/kg^2Nm120s112.39.c.5.b
- Q9Two identical asteroids are initially at rest with the only forces being gravitational attraction. Which of the following best describes the acceleration of the asteroids shown above?The acceleration will decrease until the asteroids collide.The acceleration will increase until the asteroids collide.The acceleration remains constant until the asteroids collide.There is no acceleration, the asteroids will move toward each other at constant velocity120s112.39.c.5.b
- Q10A 1,000 kg truck moving at 10 m/s runs into a concrete wall. It takes 0.5 seconds for the truck to completely stop. What is the magnitude of force exerted on the truck during the collision?5,000 N1,000 N20,000 N10,000 N120s112.39.c.4.d
