Density = mass/volume
Density = 81g/0.9cm³
Density = 90g/cm³
: )
the answer is A.) because the scientific method is used to answer problems.
This is the steps,
STEP 1: ask a question
STEP 2: state your hypothesis
STEP 3: conduct an experiment
STEP 4: analyze your results
STEP 5: make a conclusion
Answer:
Explanation:
Ionic compound are compounds formed by one atom losing an electron while the other gains electron as such the solution always contain charge ions compared to covalent solution which is predominantly formed by two atoms sharing electron. The two solution should be connected to a circuit with a bulb in turns with the same circuit, the solution that turns the bulb on is the ionic solution. This is because their charged ions conducts electricity when voltage is passed through it while the covalent solution does not conduct electricity.
Kinetic energy is KE=0.5mv^2
Since the car is mass is the smallest efor the three situations
the Kinetic energy at 30 mph
KE1=0.5 m (30)^2
the Kinetic energy at 15 mph
KE2=0.5 m(15)^2
the Kinetic energy at 0 mph
KE3=0
KE1>KE2
The Kinetic energy at 30 mph is the highest
