What causes objects to sink or float?
Answer 1: Buoyancy is an upward force caused by the pressure from a displaced fluid.
It is the force that causes wood and boats to float in water and the reason why objects feel lighter when submerged in water.
The ball will absorb water through the holes around its stitches, which will soak the twine that wraps around the cork core.At the point where its density exceeds that of the water, it will of course sink.The boy was so excited that he dropped the ball into the river, and it quickly sank out of s...
Answer: Compare the density of the object in question to the density of water.If its density is less than water, it will float.For example, oak floats because its density is 0.7 g/cm³.If the density of an object is greater than water, it will sink.
Objects float if they are light for their size and sink if they are heavy for their size.An object can be light for its size if it contains air, such as a hollow ball.Materials with a boat shape will float because they effectively contain air.Water pushes up on objects with an upthrust force.
Engine Misfiring One or more cylinders are not getting enough fuel or getting too much fuel when they are being fired by the spark plugs.This happens when the float is stuck, either in the open or closed position.The engine will stall, not idle smoothly or backfire once the carburetor float sticks.
Forces affect how objects move.They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving.Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity.So forces cause acceleration.
Unbalanced forces acting on an object cause the object's motion to speed up, slow down, or stop.Unbalanced forces cause a non-moving object to start moving.Rate of motion Rate of motion is the speed of the object or how fast or slow the object is moving.
Is the following sentence true or false if the weight of a submerged object is less than the buoyant force the object will sink?
If the weight of an object in a fluid is greater than the buoyant force, the net force will be downward and the object will sink.If the weight of an object is less than the buoyant force, the object will float.
Typically, the three most common problems related to brake pedal sink are caused by the master cylinder, a brake fluid leak, or ABS unit leak.Noticeable when holding constant pressure against the brake pedal at a stop.Pedal sinks or requires pumping to keep your car from creeping ahead.
In contrast to the attractive force between two objects with opposite charges, twoobjects that are of like charge will repel each other. That is, a positively chargedobject will exert a repulsive force upon a second positively charged object.
This is a classic symptom of a leaking booster.The engine is running rough at idle while braking because of the vacuum leak.Replace the brake booster, then recheck brake operation.The pedal going to the floor is usually caused by air in the hydraulic system.

Students should recognize that a log will float because wood is less dense than water.If you could weigh a large amount of water that has the same volume as the log, the log will weigh less than the water.Therefore, the log floats.A grain of sand will sink because sand is more dense than water.
While Object Moves When an object is standing still, there is a maximum force needed to overcome friction and start it moving.Any force less than this will be exactly balanced by the force of friction, and the object will not move.Once the object is moving, the frictional force remains constant.
Put it this way...Would you rather get hit with a car going 70 MPH, or a car going 5 MPH?
Constant direction constrains the object to motion to a straight path.Newton's second law (F=ma ) suggests that when a force is applied to an object, the object would experience acceleration.If the acceleration is 0, the object shouldn't have any external forces applied on it.
Friction is a force that occurs when two surfaces slide past one another.The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down.When objects move through a fluid, such as air or water, the fluid exerts a frictional force on the moving object.
"Floating Valves" refers to a condition in which the valve-springs fail to fully close the valves, allowing them to "float" during the stroke cycle. Floating valves can result in valve-piston contact with consequent catastrophic mechanical damage. This is caused by revving the engine past it's re...

What factors can cause brakes to fade or fail? Excessive use of the service brakes results in overheating and leads to brake fade.Brake fade results from excessive heat causing chemical changes in the brake lining, which reduce friction, and also causing expansion of the brake drums.
A float plane is a type of seaplane. Float planes land on extended floats like a normal airplanes landing gear, as opposed to boat-hulled sea planes. Float planes are usually land airplanes which have been converted to land on water, although some aircraft are specially designed for this purpose....
A drivers eyes should be moving close to every two seconds. Looking at any one object too long while driving may cause you to miss something else coming into your path.Also moving your eyes keeps you more alert to what is happening around you. Studies show more brain activity with eye movement.

Why do objects inside the car appear to be stationary when compared to the objects outside of the car?
Think of the car as a mobile container, holding items being transported, the item doing the transporting is in motion, and attached to the inside are the items being moved. so the total speed of the items being moved is the same as the item/vehicle doing the moving. Because the vehicle in motion ...

kinetic energy is mass x velocity, so if there are going the same speed, the 18 wheeler.
Yes, that's right, a change in the direction of motion results in an acceleration even if the moving object neither sped up nor slowed down.That's because acceleration depends on the change in velocity and velocity is a vector quantity — one with both magnitude and direction.
Water is heavier than gasoline, it will pool at the lowest point of the fuel tank.

It depends on what kind of car you have. Three things are needed to "make fire" in the engine: fuel, air, and spark. If any of these is interupted then it can sputter or just not run. How those three gets there depends on the car. Older, carbureted engines mixed fuel and air in the carburetor and...
Because you drove up the left or right sidewalk.
This refers to aerodynamics? If so, it does faster when the object has less friction with the air, wind resistance is a major factor when it comes to getting an object to a certain speed. The more streamline an object the quicker it can move throught the air
A fire would be the main cause but if there are no flames you should have the engine checked for problems under the hood. There maybe a leak of some sort and it may be burning on the engine.
I'd say to check to see that the Blower motor kicks on
It may be in need of a good tune up.
Worn out front shocks and struts will make a clunking noise when you go over small box. The strut may actually allows the tire to hit the fender well.
