NASA scientists are busy planning a fourth trip to the moon, and are planning to recover 50 kilograms of BHM. What amount of space do they need to plan for in the space shuttle to account for this mass of BHM? (Hint: remember the units required to calculate density!)

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy

What are the options? physical property can be color, smell, opacity, viscosity, density, infra red spectrum, melting and boiling points, attraction and repulson to magnets, etc.

Ithink the answer is d
