Why can the volume of a sample of plasma change when the substance is moved from one substance is moved from one container to another?
a. plasma is made of charged ions and electrons, so they interact differently in different places.
b. plasma can have lots of space between its particles, so naturally expands compresses.
c. plasma is made of neutral atoms that can split into separate ions and electrons when placed in a new container.
d. plasma can change between a rigid shape and free-moving form, so it will have different volumes in different containers.
answer : her weight is lower on venus because the acceleration due to gravity is lower.
venus is also called as earth's twin. this is because both the mass and the size of earth and venus are almost same. the acceleration due to gravity on earth is while on venus is .
so, when shari measure her weight on venus she found her weight is lower on venus. this is because the acceleration due to gravity is lower on the surface of venus as compared to the earth.
i.e. weight depends on g.
so, correct prediction is (b)
you will hear a higher pitch due to a higher frequency.
