3. B.700 N. (Your Mass does not change).
But the question talks about weight, not mass
Sure, I can help you with your work! Here are the answers to the questions:
1. The rate of change of position is called A. Speed.
2. The difference between speed and velocity is the A. direction. Speed only represents the magnitude of the motion, while velocity includes both magnitude and direction.
3. If you weighed 700 N on Earth, you would weigh C. 1,400 N on the new planet. Weight is directly proportional to mass and gravitational acceleration.
4. Every force has a(n) C. opposite force, which is measured in Newtons. The opposite force is called the reaction force, according to Newton's third law of motion.
5. As the ball leaves your hand, the force(s) acting on the ball are D. both gravity and your hand. Gravity continuously acts on the ball, and your hand initially imparts a force on the ball to set it in motion.
6. Force is similar to displacement and velocity in that C. it can describe motion. Force, displacement, and velocity are all physical quantities that are used to describe the motion of objects.
7. In every energy transformation, some energy is always "lost" in the form of D. thermal energy. Thermal energy represents the energy lost as heat during energy conversions.
8. In a nuclear power plant, nuclear energy is first converted into C. chemical energy. Nuclear energy is used to produce steam through nuclear reactions, and the steam is then used to turn turbines, which generates electrical energy.
9. A generator is a device that produces A. kinetic to electrical energy conversion. A generator converts mechanical energy (kinetic) into electrical energy using electromagnetic induction.
10. A limiting factor for using nuclear energy is C. waste. Nuclear energy produces radioactive waste that needs to be carefully managed and disposed of to prevent environmental and health hazards.
