1. read the procedure and safety
information, and complete the lab
form.
2. find a pencil that will fit entirely in
a 100-ml graduated cylinder
below the 90-ml mark.
3. measure the mass of the pencil in
grams with a balance.
4. put 90 ml of water (initial volume)
into the 100-ml graduated cylin-
der. lower the pencil, eraser first,
into the cylinder. push the pencil
down until it is just submerged.
hold it there, and record the final
volume to the nearest tenth of a
milliliter

20 pts ‼️ an unmanned spacecraft travels to mars. mars has a lower strength of gravity than earth. where in the image is the spacecraft’s weight the greatest?

An unknown insoluble substance displaced the water shown. it's mass is indicated on the triple beam balance. mass = a. 694 b. 693.5 c. 693.0 d.693.8

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
