How do mimetic forces differ from normative forces?

Mimetic forces result from responses to uncertainty. Most organizations face great uncertainty. Senior executives are not sure exactly what products, services or technoligies will achieve desired goals, and sometimes the goals themselves are not clear. When facing this uncertainty, mimetic forces, the pressure to copy or model other organizartions occur. Executives observe an innovation in a firm abd if it is successful, the management practice is quicly copied. Normative Forces result from common training and professionalism. Normative forces are pressures to change to achieve standards of professionalism and to adopt techniques that are considered to be up to date and effective by the professional community. Changes can be in any area, like information technology, accouting requirements or collaborative realtionships with other organizations.

What are city speed limits miles per hour as a rule?

There is no "as a rule". Different countries - and even different cities within the same country - have different speed limits.

What is the output per hour of concrete breaker?

I am pretty sure that such machines come in different sizes, and therefore in different capacities. Consult the technical specifications of individual manufacturers if you want to know the output of a specific machine type.

How could you represent the speed and direction of a car if you able to measure its position vs time?

If s is the vector which denoted the position at time t, then the vector ds/dt is the required vector. Its magnitude is the car's speed and its direction is the car's.

How many mili liters in a liter?

Milligrams can't be converted to milliliters. Milligrams measure mass, while milliliters measure volume.

How do you apply torque on a pen if it stands vertically?

spin it. Torque is a rotational force applied to an object. It is measured on a tangent to the centerline of the rotation in force-distance from that center. ie: foot-pounds, newton-meter, etc..

Why is relative velocity AFTER equal to Vf2 minus Vf1 but relative velocity BEFORE equal to V1 minus V2 in the coefficient of restitution formula?

relative velocity is defined as the time rate of change of one object with respect to another object.the relative velocity depends upon the observer i.e.if the velocities of two objects are same then the relative velocity also seems to be equal.

Is it possible to have a negative speed?

No, Speed is always greater than or equal to zero. However, velocity can be negative, which just means you have a positive speed in the opposite direction! (scalar(number) versus vector).

What is a car's kinetic energy if it is 1500 kilograms and is moving at a speed of ten miles per second?

Are you sure you mean 10 miles per second? That is a speed of 36,000 mph (unless you are referring to the speed of the car relative to the orbit of the earth as the earth orbits the sun, but that is approx 19 miles per second).

I think you mean 10 metres per second (as you've used a metric measure for the mass of the car).

kinetic energy = ½ × mass × velocity²

→ KE = ½ × 1500 kg × (10 m/s)²

→ KE = 75000 kgm²/s² = 75000 Joules = 75 kJ

Which does a ball roll farther in grass or dirt?

Neither. The ball rolls faster on cement, not grass, or dirt.

Does the length of a barrel and the type of propellant used affect the distance and the accuracy of the paintball?

These are two separate questions, but yes, barrel lenght and propellant affect the distance and accuracy of paintballs.

What are cons to legal Immigration?

Some cons of immigration is that the U.S. population increases, not educated and poor immigrants are lowering the GDP of the country, and is also lowering standard living in the United States.

Is kinetic energy always less than the potential energy?

no


Yes they can, in a solution of a single type of atoms, at absolute zero; This is the point at which something physically has zero energy (none in the molecules whatsoever), and there would be no potential energy in the bonds between molecules

What are balanced and unbalance net force?

The "net force" is the vector sum of all forces acting on an object.

"Balanced forces" means that the net force is zero.

"Unbalanced forces" means that the net force is non-zero.

Note that unbalanced forces on an object will cause an acceleration - the object's velocity will change.

CAN AN Object accelerate and be moving at a constant speed?

Yes, it's direction may be constantly changing which would mean it is still accelerating.

If you run a 40 in a 4.24 how is that in mph?

40 meters in 4.24 seconds equates to a speed of 21.1 miles per hour.

How fast is 116 kph?

116 kilometers per hour (kph) is 72.1 miles per hour.
