Answer:
Honda Civic
Explanation:
As per the structural design and purpose of use for vehicle, Both are different from one another in various terms such as size, strength and design.
Mack trucks are very huge trucks especially designed for loading heavy objects. They are even used to carry heavy consignments such as cars.
Whereas Honda civic has a sleek structural design and have a very fragile body as it is sedan car, so if there will be a head-on collision between these two vehicles, certainly there will be a huge impact force on civic and it will even smash into pieces if any of the vehicle have high speed.
False it only melts when its thermal energy increases. plus an ice cube has no mechanical energy.
Answer:
An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).
Explanation:
Answer:
C
Explanation:
Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle.
Answer:
The options are:
Test 1: Mix a teaspoon of sodium bicarbonate into a cup of warm water to see if it dissolves.
Test 2: Mix a teaspoon of sodium bicarbonate into a cup of vinegar to see if it fizzes.
Test 3: Heat a teaspoon of sodium bicarbonate in the oven to see if its melting point is less than 400 degrees Fahrenheit.
Which statement provides the best assessment of his tests?
The answer is Test 2: Mix a teaspoon of sodium bicarbonate into a cup of vinegar to see if it fizzes.
This is because it will indicate the chemical property of the sodium bicarbonate as a result of its reaction with another chemical compound, a vinegar.
Tests 1 and 3 will show a physical property of the substance as a result of the physical characteristics such as solubility and melting point .
