Answer:
Option B - 360 J
Explanation:
One of the formulas used to find out how much work was done is : 
E = 0.5×m×v² (where m is the mass and v is the velocity) 
Now we substitute values from the question and simplify : 
E = 0.5×500×1.2²
E = 250×1.2²
E = 250×1.44
E = 360 J 
So our answer is Option B
Hope this helped and have a good day 
 
        
             
        
        
        
Hybrid
<u>Hybrid</u> modified the concept by adding an internal combustion engine and marketing hybrids that were part electric and part gas powered.
- The driving wheels of hybrid vehicles receive power from their drivetrains. 
- A hybrid car has numerous sources of propulsion.
- There are numerous hybrid configurations. 
- A hybrid vehicle might, for instance, get its energy from burning gasoline while alternating between an electric motor and a combustion engine.
- Although they have primarily been employed for rail locomotives, electrical vehicles have a long history of integrating internal combustion and electrical transmission, like in a diesel-electric power-train. 
- Because the electric drive transmission directly substitutes the mechanical gearbox rather than serving as an additional source of motive power, a diesel-electric powertrain does not meet the definition of a hybrid.
- Only the electric/ICE hybrid car type was readily accessible on the market as of 2017. 
- One type used parallel operation to power both motors at the same time. 
- Another ran in series, using one source to supply power solely and the other to supply electricity. 
- Either source may act as the main driving force, with the other source serving to strengthen the main.

The option that could be the hypothesis for this experiment is that D. Abstract paintings may elicit feelings of stress as students try to determine the meanings of the paintings; therefore, abstract paintings may cause college students to report lower feelings of peace.
<h3>What is a hypothesis?</h3>
It should be noted that a hypothesis simply means the proposed explanation made on the basis of limited evidence.
From the information, Smith is conducting an experiment to determine if paintings of landscapes produce more peaceful feelings than abstract paintings.
Therefore, the option that could be the hypothesis for this experiment is that abstract paintings may elicit feelings of stress as students try to determine the meanings of the paintings; therefore, abstract paintings may cause college students to report lower feelings of peace.

Answer:
Comparison Microscope 
Explanation:
The Comparison Microscope allows for comparison between two objects or samples by placing them side by side. 
It is primarily used in criminology for ballistics which makes it ideal to find out if bullets, shells, or cartridge cases were fired from a specific weapon.
