Answer:
The oldest functioning car is La Marquise, a steam-powered, four-wheeled, four-seater vehicle, manufactured by De Dion Bouton et Trépardoux (France) in 1884; three years later it won the world's first automobile race, powering along the 30.5-km (19-mile) track at an average of 42 km/h (26 mph) from Paris to Neuilly, .
The work done on the block is B) 400 J
Explanation:
The work done when lifting an object is equal to the change in gravitational potential energy of the object:
where
m is the mass of the object
g is the acceleration of gravity
is the change in height of the object
In this problem we have:
(mg) = 100 N is the weight of the block (product of mass and acceleration of gravity)
is the change in heigth of the object
Substituting, we find the work done:

Deuterium is also known as heavy hydrogen and takes the symbol 2H. What makes this heavy is due to the additional neutron present in it. Therefore, everything that is being mentioned above as the description of deuterium is applicable. Therefore, the answer would be option E: All of the above. Hope this helps.
Answer:
Weight = 88N
Explanation:
Given the following data;
Acceleration due to gravity on moon = 1.6m/s²
Weight on earth = 539N
To find the weight on moon.
First of all, we would calculate the mass;
Weight = mass * acceleration due to gravity.
We know that acceleration due to gravity on earth is equal to 9.8m/s²
Substituting into the equation, we have;
539 = mass * 9.8
Mass = 539/9.8
Mass = 55 kg.
Now, we solve for the weight on moon.
Weight = 55 * 1.6
Weight = 88N
Answer:
Potential Energy
Explanation:
The electron transport chain is a series of proteins and organic molecules located in the inner membrane of the mitochondria.During electron transfer and proton pumping electrons are moved from a higher energy level to a lower one and in the process release energy.This energy is used to make ATP.It is stored in the electrochemical gradient of protons and it has to be released for electron transport to continue.
