What is the work done by a frictional force on an object when dragged along a rough surface? What is the force applied by a machine to overcome another force? What is the relation between force and acceleration?
Your body has mass and in the earth's gravitational field, your body has weight as well. When you are sitting on a chair and you don't collapse downwards, we can conclude that there is a force supporting and balancing out your weight. That force is opposite and equal and is an ...
Many people feel that the U-6 is the true unemployment rate because it counts everyone who would take a full-time job if one were offered to them. It’s an effective way of measuring the slack in the labor force. Another use for the unemployment rate is to calculate themisery index. T...
The SI unit of density is: View Solution What is the SI unit of density? View Solution The coefficient of viscosity n of a fluid moving steadily between two surfaces is given by the formula, f=nAdVdx where f is the frictional force on the fluid, A is an area in the fluid and dV...
The unemployment rate formula is calculated by dividing the number of unemployed individuals in the workforce by the total labor force. This main category of unemployed people is typically broken down into four different categories based on how they affect the economic system: structural, frictional,...
For a level surface, if the coefficient of friction between the object and the surface is μ, then the frictional force isAccording to Newton’s second law, this friction force applied to the moving object (a vehicle) produces a proportional deceleration:或者Now...
Step 7: Use the same formula to find the new accelerationUsing the same formula for the new mass:a′=Fm′Substituting the values:a′=80N25kg Step 8: Calculate the new accelerationNow, perform the calculation:a′=8025=3.2m/s2 Final Answer- The acceleration of the box when the mass is 50...
Frictional Unemployment. Cyclical Unemployment. Structural Unemployment. Institutional Unemployment. Is structural unemployment voluntary or involuntary? This occurs when there is some force that prevents the real wage rate from decreasing to the real wage rate that would equilibrate supply and demand (such...
For a level surface, if the coefficient of friction between the object and the surface is μ, then the frictional force isAccording to Newton’s second law, this friction force applied to the moving object (a vehicle) produces a proportional deceleration:或者Now...
different things One common use is forforce Force is measured in units like Newtons The formula F=ma(where"F" is force,"m" is mass, and"a" is acceleration) is a fundamental relationship If we know the mass of an object and how it is accelerating, we can calculate the force acting ...
