What happens to the magnitude of the fluid friction acting on a submarine as the submarine?
As a submarine moves through water, the magnitude of fluid friction, or drag, increases with speed due to the turbulent flow of water around its hull. At low speeds, the drag is primarily laminar and lower, but as the submarine accelerates, the flow becomes turbulent, leading to greater resistance. Additionally, factors such as the shape of the submarine and its surface roughness also influence the overall drag experienced. Thus, as the submarine increases its velocity, the fluid friction acting on it tends to increase significantly.

What happens to the magnitude of the fluid friction acting on a submarine as the submarine's speed increases?
As a submarine moves more quickly through the water, the fluid friction will increase. The two (the magnitude of the speed and the magnitude of fluid friction) are directly proportional. That means what happens to one happens to the other. If one goes up, the other goes up. And if one goes down, the other goes down.
What is magnitude of friction force?
The magnitude of the friction force is dependent on the normal force acting between two surfaces. It is given by the equation F_friction = μ * N, where μ is the coefficient of friction and N is the normal force.
If you push a crate across a factory floor at constant speed in a constant direction what is the magnitude of the force of friction on the crate compared with your push?
The magnitude of the force of friction on the crate would be equal to the magnitude of your push. This is because the crate is moving at a constant speed, indicating that the force you are applying is balanced by the force of friction acting in the opposite direction.
What is the force of friction acting on a crate that slides across the floor?
The force of friction acting on a crate sliding across the floor is equal in magnitude but opposite in direction to the force applied to move the crate. It depends on the coefficient of friction between the crate and the floor, as well as the weight of the crate.
What is the formula to calculate the magnitude of the force of static friction on an object resting on a level tabletop?
The formula to calculate the magnitude of the force of static friction on an object at rest on a level tabletop is given by f_static = μ_s * N, where f_static is the force of static friction, μ_s is the coefficient of static friction, and N is the normal force acting on the object.
If we push a crate at a constant velocity how do we know how much friction acts on the crate compared to our pushing force?
If the crate is moving at a constant velocity, then the force of friction acting on the crate is equal in magnitude and opposite in direction to the force you are applying to push the crate. This means that the force you apply to push the crate is balancing out the force of friction acting against it. By measuring the force you are exerting and observing the constant velocity of the crate, you can infer the magnitude of the friction force.
How can you increase the magnitude of friction between two surfaces How can you decrease the magnitude of friction?
To increase friction, you can increase the roughness of the surfaces in contact, increase the normal force pressing the surfaces together, or use materials with higher coefficients of friction. To decrease friction, you can use lubricants to reduce surface roughness and create a barrier between the surfaces, reduce the normal force acting on the surfaces, or use materials with lower coefficients of friction.
What is the magnitude (size) and direction of the cumulative force acting on the car shown in the picture above?
The cumulative force acting on the car is the vector sum of all forces acting on it. To determine the magnitude and direction of this force, you would need to know the individual forces acting on the car (such as friction, gravity, and engine force) along with their magnitudes and directions. This information is necessary to compute the net force acting on the car.
If friction acting on the car is the action force then what is the reaction force and what object does it act on?
The reaction force to the friction acting on the car is the friction force acting on the road. It acts on the car in the opposite direction to the friction force acting on the car.
How can a submarine float and which force is acting on it?
The buoyant force keeps a submarine afloat.
What is required to get a stationary object moving?
An outside force is needed. If friction comes into play (which it likely will), the magnitude of the applied force must be greater than the force of friction acting upon the object in order for the object to move. FYI, the force of friction is equal to the coefficient of static friction times the normal force (equal to the weight of the object).
Will a submarine sink or float when it's weight is equal to the upthrust acting on it?
If the weight of the submarine is equal to the upthrust acting on it, the submarine will float. This is due to Archimedes' principle, which states that an object will float when the buoyant force acting on it is equal to the gravitational force pulling it down.
