While travelling along a highway a drivers velocity is 9 m/s. In 12 seconds, the car has gone for 108 m.
<u>Explanation:</u>
The car travelling along the highway has a uniform velocity of 9 m/s. therefore to calculate the distance travelled by the car with the uniform velocity in 12 seconds, simple formula of velocity is to be employed.
Thereby, as we know that
The displacement is along the highway with uniform motion, therefore, distance=displacement
Given that,
Velocity = 9 m/s
Time = 12 s
Putting the values in the formula, we get,
Therefore, the car travels for 108 m in the 12 seconds while travelling along highway with 9 m/s of velocity.
Answer:
No.
Explanation:
The force that two particle experience is inversely proportional to the sqare of the distance, this is:
for a distance D
If we move them so that D is doubled:
= 
Then the force they experience is one fourth of the original.
B.riding on a ferris wheel
E.a satellite orbiting the Earth
Explanation:
A person riding on a ferris wheel and a satellite orbiting the earth both depicts circular motion.
Circular motion is the motion of a body about a fixed axis or center.
- The motion path of the body forms a circle around the center.
- In circular motion, the travel path is along a circle.
- An orbiting satellite traces out its orbit round the earth.
- At certain times, it passes through that point over and over again.
- This is similar to that of a ferris wheel
Other options gives other types of motion.

Answer:
E = 7231.2 [kWh]
Explanation:
All systems that produce work in the mechanical form of movement or heat, they have an efficiency that depends on the construction technology, ideally in each of these equipments is that their efficiencies are as high as possible, that is, its efficiency is close to 100%. For this case we have an equipment with 60% efficiency, this heating system is characterized since of the 12,052 kWh, it uses 60% of this value only to heat the house, the rest of energy is known as lost.
E = 12,052 * (60/100)
E = 7231.2 [kWh]
This amount of energy 7231.2 [kWh] is used for heating purposes.
