Question 7 Five new measurements (the yellow boxes) for the acceleration due to gravity, g, are plotted on a new dart board as shown below. Which of the following statements best describes the comparison between the measured values and the accepted value for g at this location of 9.81 m/s (the bullseye)? 9.40m/s? 9.71m/s² 9.81m/s 9.95m/s 10.1m/s 9.15m/s? Accurate but not precise O Accurate and precise O Precise but not accurate Neither accurate nor precise

The Earth is about 81 times more massive than the Moon.The Earth and the Moon apply gravitational forces to each other. The magnitude of the gravitational force acting on the Earth is the gravitational force acting on the Moon.a greater thanb) equal toc) less thand) not enough information to tell

Question answer

An asteroid starts at rest infinitely far from an Unknown planet. The asteroid has a mass of 5.00×104 kg. The mass of the planet, and the radius of the planet are given below. MAsteroid= 5.00x104 kg MPlanet-8.60x1025 kg Rplanet= 2.50x107 m What is final velocity when the asteroid hits the planet? 4.3 m/s 9180 m/s 5050 m/s 21400 m/s 1.15 x 103 m/s

Three objects A, B and C are in a straight line, as shown below If the value of the gravitational constant  G = 6.67 ×10^(-11) kg^(-1) m^(3) s^(-2) Calculate : A. The magnitude of the gravitational force acting on the object BB. the direction of the gravitational force on the object B solve subparts A,B based on image

QUESTION 2 At a location where gravity acceleration constant g=9.80 m/s2, a projectile returns to its original height after 5.9 seconds, during which time it travels 74.1 meters horizontally. If air resistance can be neglected, what was the projectile's initial speed: vo = (Note: For fill in blank, I have set the unit for the answer. So, you just need to provide a number - Please write your numerical answer with all digits and do not use scientific notation. If you are not sure about the number of significant figures, you can keep the number of figures as many as possible - You will not be punished for doing this. ) m/s ? QUESTION 3 An airplane needs to reach a forward velocity of 203.0 km/h (Please pay attention to the unit km/h here - km = 1000 m, h = hour) to take off. On a 2000-m runway, what is the minimur uniform acceleration necessary for the plane to take flight if it starts from rest?
