Answer:

A balance and a graduated cylinder.

Explanation:

<u><em>Density</em></u> is the  relationship between mass and volume of a substance, the formula is:

ρ=m.v

Where m is the substance mass, and v is the volume.

If a student wants to measure the density of seawater, he or she should use a Balance, to measure the mass of the sample. And then use a Graduated cylinder, is a volumetric instrument that allows to contain liquids and then measures the exact volume of the sample.

Once the student obtains the mass and the volume, he/she has to replace the data in the density formula and so obtain the density of seawater.

The graph shows the kinetic energy of both a school bus and a pickup truck as they move at various speeds. Under which of the fo
MakcuM [25]

The correct answer is B. The pickup truck is moving at 4 m/s and the school bus is moving at 2 m/s.

Explanation:

The kinetic energy is related to how fast a body moves (speed), as well as, the amount of matter in the object (mass). Due to this, even if the bus and the truck move at the same speed they do not have the same kinetic energy. Indeed, the graph shows in general the kinetic energy is higher for the school bus.

However, this does not occur if the truck moves at 4 m/s and the bus moves at 2m/s because, at this speed, the kinetic energy of the truck is 30 kilojoules, while the kinetic energy of the bus is around 15 kilojoules, which is lower. According to this, the correct answer is B.
