When it was first made, it was heavier

Explanation:</u></h3>
So there was originally air in the Ice Cream because they fluff it up like that. When it melts, those are gone.
Answer:Orient your line of sight directly above the measurement markings.
Explanation: parallax error is a type of systematic error that occurs when an observer views a measurement marking at a wrong angle. This causes a noticeable disparity in results obtained. Therefore the best way to prevent this error is to view and record the data from the correct angle. This can be obtained by:
-Place the measurement device on its edge so it is level with the object being measured.
-Seek out the finest possible edge of the measurement device, or use a device with finer edges.
In conclusion, ask other observers to also take the reading and get an average of their results. It can help cancel out parallax error results.
Answer:
pressure of solid depends on:
1/magnitude of the force
2/contact area
pressure in solid depends on:
1/depth inside the fluid.
2/density of the fluid.
3/Acceleration due to gravity.
Explanation:
1/magnitude of the force:the pressure is directly proportional to the magnitude of the force(thrust). The larger the force, the higher is the magnitude of pressure on the surface.
2/Contact area: the pressure is inversely proportional to the surface area of contact. The larger the contact area, lower is the magnitude of the pressure.
Answer:The main formula is v² = u² + 2as
Explanation:
S=½(u +v)t
t = v+u/a
S=½(v-u)(v+u/a)
S=½v²+uv-uv-u²/a
2as=v²-u²
