The moon does not fall to earth because: The moon is beyond the main pull of Earth's gravity. The moon is pulled by the sun and planets as well as by Earth. The gravitational force provides the required centripetal force for the moon to have its tangential speed around the Earth. The net force on the moon is zero. The moon is in earth's gravitational field. Question 3 (4 points) The tallest mountain in our solar system is Mt. Caloris...

Which of the following statements are true? Because the Earth has mass it produces gravity. There is no gravity at the space station I need to do work to move a satellite from lower to higher orbit. Because the force of gravity is a conservative force and because it acts as a centripetal force it does no work, the mechanical energy of Earth is conserved and it will not crush into the Sun. Since Moon has no air, there is...

Mark each of the following statementsas true or false. If a statement refers to "two objects"interacting via some force, you are not to assume that these twoobjects have the same mass. Every force has one and only one 3rd law pair force. true or false? The two forces in each pair act in opposite directions. true or false? The two forces in each pair can act on the same object or ondifferent objects. true or false? The two forces in...

Learning Goal: To understand Newton's law of gravitation and the distinction between inertial and gravitational masses. In this problem, you will practice using Newton's law of gravitation. According to that law, the magnitude of the gravitational force Fg between two small particles of masses m1 and m2 separated by a distance r, is given by m1m2 T2 where G is the universal gravitational constant, whose numerical value (in SI units) is 6.67 x 10-11 Nm2 kg2 This formula applies not...

Lagrangian points (also Lagrange point, L-point, or libration point), are the five positions in an orbital configuration where a small object affected only by gravity can theoretically be stationary relative to two larger objects (such as a satellite with respect to the Earth and Moon). The Lagrange points mark positions where the combined gravitational pull of the two large masses provides precisely the centripetal force required to rotate with them. The L, point lies on the line defined by the...

Select every statement that is true about radioactivity (more than one may be selected): a. Gamma decay is a helium nucleus being emitted from the nucleus of a larger atom. b. Beta decay is a neutron in the nucleus of an atom splitting into a proton, which stays in the nucleus, and an electron, which is ejected. c. The products of a decay reaction are often themselves radioactive. d. Different isotopes of the same element often react differently in radioactive...

Choose the true statement or statements below about a magnetic field. If more than one choice is correct, you must indicate all. A magnetic field Part A is non-conservative. that is constant can induce an emf in a conducting loop in the vicinity. inside a charging parallel plate capacitor varies with distance from the center in the same way as the magnetic field inside a current-carrying cylinder. always exerts a force parallel to the direction of motion of a charge....

Which of the following statements are TRUE? There may be more than one correct answer; select all that are true. A standard normal random variable cannot take on negative values. The normal distribution is symmetric about the mean mu. A normal distribution cannot have a negative mean. In a normal distribution, the mean and median are equal. If Z is a standard normal random variable, then P(Z > 41278) is very close to 0.
