Answer:
They are able to balance torques due to gravity.
Explanation:
When two friends of different masses will balance themselves on see saw then at equilibrium position the see saw will remain horizontal
This condition will be torque equilibrium position where the see saw will not rotate
Here we can say
here we know that force is due to weight of two friends
and their positions are different with respect to the lever about which see saw is rotating
since both friends are of different weight so they will balance themselves are different positions as per above equation
A vehicle's power steering system consists of components that generate and transmit power to the wheels.
Answer:
Precision
Explanation:
You can be very precise but inaccurate, as described . You can also be accurate but imprecise. For example, if on average, your measurements for a given substance are close to the known value, but the measurements are far from each other, then you have accuracy without precision. Precision is independent of accuracy. You can be very precise but inaccurate, as described above. You can also be accurate but imprecise. For example, if on average, your measurements for a given substance are close to the known value, but the measurements are far from each other, then you have accuracy without precision. Precision refers to the closeness of two or more measurements to each other. Using the example above, if you weigh a given substance five times, and get 3.2 kg each time, then your measurement is very precise.
Answer: Movement of heat takes place from object with higher temperature to one with lower temperature until both objects are in thermal equilibrium.
Explanation:
<u>Zeroth law of thermodynamics states that: </u>Two objects which are not in thermal equilibrium that is have different temperatures when placed in contact would attain thermal equilibrium after some time. The heat from hotter object would transfer to colder one until equilibrium is achieved.
Formula: F=w*d => d=F/w
Since F=500j, w=50N
=>d= 500/50=10m
So, D=10m
