Answer: Force on the truck is equal to force on the car.
Explanation: According to the Newton's third law of motion which states that; For every action, there is an equal and opposite reaction. These pair of forces are regarded as action - reaction forces. These size or magnitude of the forces on the colliding objects are equal or the same, while the direction of the colliding objects are opposite.
In the scenario above, both truck and carry have the same mass, however, the damage suffered by the car is based on its smaller mass which makes it unable to withstand the acceleration resulting from the collision.
ma = m(-a)
m= mass, a= acceleration
1. As of right now, our solar system only includes asteroids and they are found in Kuiper Belt next to Saturn.
On May 6, 2020, scientists have discovered a mysterious blanket of darkness approximately 1,000 light years away from our solar system. However, in this case, black holes would not be a correct answer.
Even though constellations may seem close, they are actually far away since the size of the stars are immense and can be visible from light years away. Constellations are not in our solar system.
Galaxies are groups of solar systems so therefore galaxies is not an answer.
2. Ptolemy was the man who proposed the early Earth-centered model of the universe and his model was called the Ptolemaic model also known as the geocentric model.
3. The planet that is most similar to Earth in mass and diameter is Venus.
4. The inner planets in our solar system are formed from dense elements and that is why they are able to withstand the intense of the sun. Meanwhile the outer planets were formed from gaseous materials but Pluto is so cold that its elements are hardened and dense.
5. The answer would be D since they orbit in the same direction and on the same plane.
6. The speed of rotation determines the length and duration of day on a planet.
7. The answer would be D since they have to have their own gravity, have a path clear of smaller bodies , and orbit a star,
Answer: fourth option) <span>the change in the height of a liquid in a tube that is open on one end
</span>
Justification:
When the tube is open the liquid in it is subject to changes in atmosphere pressure, so it cannot not be reliable, because the depending on the weather conditoins and the altitude of the place, the measurement would differ.
The thermometers have to be closed so that the changes in the liquid expansion reflects only the change in temperature.
Note that the other two phenomena (change in pressure of a gas and change in resistances of metals) are very well related to changes in temperature and, so, devices based on them would result in precise temperature measurement devices.

The answer that would best complete the given sentence above is cubic meter. The standard unit for measuring volume is the cubic meter (m^3). Volume is the quantity or the measurement of the amount of space that can be or is being occupied by matter. The metric unit for volume includes "liters" and "milliliters".
