Give an example in which the net force acting on an object is zero, yet the net torque is nonzero. True or False: Gravity and friction are examples of external forces. What is the force applied by a machine to overcome another force? According to the universal law of gravitat...
Seasoning the eggs, however, has a lot of float. You can add salt to the raw egg mixture, while the eggs are cooking, and even after they’ve cooked. The importance of slack should not be understated. Calculating the float or slack of all activities in the project is crucial for bette...
The bottom of a submerged object is deeper under water than the top, so the pressure on the bottom of that object is greater than that on the top. The net force upwards on the ball is defined as the buoyant force. When this upward force is greater than the gravitational force (the obj...
The kinetic fiction force only applies to an object that is moving (hence "kinetic"), and is otherwise known as sliding friction. This is the force that opposes sliding motion (pushing a box across floorboards), and there are specific coefficients of friction for this and other types...

Calculating your marketing ROI helps you determine how effective and valuable your marketing activities and channels are. Depending on your business, some marketing channels perform better than others. 2. Churn rate Churn rate measures the percentage of customers who stop doing business with your compa...
N is thenormal force Determining the amount of force needed to overcome static friction is more complex than calculating kinetic friction. This is because static friction gets progressively stronger as more pulling/pushing force is applied. For instance, if you want to slid a table across the flo...
