What else can I help you with?
Analyze the following sentences. Write true if the statement is correct or false if it's not.1. Friction is the force that is present whenever to surfaces are in contact?
True. Friction is the force that resists motion when the surface of one object comes in contact with the surface of another
What kind of friction causes a box you are pushing across the floor to stop when you stop pushing?
is it gravity,friction,inertia or balanced force All surfaces, even highly polished metal surfaces, are covered with microscopic dips and bumps. When two surfaces are in contact, the surfaces stick to each other where the dips and bumps on one surface touch the dips and bumps on the other surface. Friction is caused by the sticking of the two surfaces at these bumps and dips. Static friction occurs when the force applied to an object is not large enough to break the connections between the surfaces. When the force applied is strong enough, the connections are broken and the object starts sliding. As the object slides, new connections are continually being formed and broken. The formation of these new connections between the sliding surfaces causes sliding friction. GravityOne non-contact force you are very familiar with is gravity. Gravity is a non-contact force that every object exerts on every other object due to their masses. You and this book both have mass. As a result, you exert a gravitational force on this book, and this book exerts a gravitational force on you. In the same way, you and Earth exert gravitational forces on each other. The gravitational force between two objects is an attractive force that tends to pull the two objects closer together. You've experienced this attraction when you fall to the ground after jumping upward. The size of the gravitational force between two objects depends on the masses of the objects and the distance between them. The gravitational force between two objects increases if the mass of one or both of the objects increases. If two objects move closer together, the gravitational force between them increases
How does condensation work on glass surfaces?
Condensation on glass surfaces occurs when warm, moist air comes into contact with a cooler glass surface. The air cools down upon contact with the glass, causing the moisture in the air to condense and form water droplets on the glass. This process is similar to how dew forms on grass in the morning.
What conditions are needed for static friction to come into play?
Static friction comes into play when an object is at rest or stationary and a force is applied to it that is not enough to overcome the force of static friction. The surfaces of the object and the surface it is in contact with must be in contact and in fact.
What is considered a food contact surface?
A food contact surface is any surface that comes into direct contact with food during preparation, processing, serving, or storage. This can include countertops, cutting boards, utensils, equipment, and packaging materials. It is important for these surfaces to be clean and sanitized to prevent contamination.
How is friction formed?
Scientists are not completely sure what causes friction; however, it is thought to be caused by the interactions between the tiny bumps on surfaces as they rub against each other. The bumps on each surface bend and exert a force on each other making it hard for the surfaces to slip over each other.
Why is bleach slippery when it comes into contact with surfaces?
Bleach is slippery when it comes into contact with surfaces because it reacts with oils and fats on the surface, creating a soapy residue that makes it feel slippery.
What does your immune system form when it comes in contact with an allergen?
antibodies are formed when the immune system comes in contact with the allergen.
How does grease lubricate the surfaces it comes in contact with?
It allows contact parts to glide against each other with minimal friction.
Does vinegar damage metal when it comes into contact with it?
Yes, vinegar can damage metal when it comes into contact with it. The acidic nature of vinegar can cause corrosion and tarnishing on metal surfaces.
What can cause bumps where your urine comes out?
Infections like warts and herpes can cause bumps where the urine comes out (that is, around the urethral opening).
What happens when an atom that looses an electron comes in contact with an atom that has gained an electron?
An ionic molecule is formed.
Analyze the following sentences. Write true if the statement is correct or false if it's not.1. Friction is the force that is present whenever to surfaces are in contact?
True. Friction is the force that resists motion when the surface of one object comes in contact with the surface of another
How is mist formed outside in the cold?
Mist is formed outdoors in the cold when warm, moist air comes into contact with cooler air or surfaces, causing the water vapor in the air to condense into tiny droplets. This process is known as condensation and it occurs when the air temperature drops below the dew point temperature.
Does marble stain when it comes into contact with water?
Yes, marble can stain when it comes into contact with water, especially if the water contains minerals or impurities that can penetrate the porous surface of the marble. It is important to promptly clean up any spills on marble surfaces to prevent staining.
What kind of bond is eventually formed when a chlorine atom comes into contact with another chlorine atom?
Nonpolar Covalent Bond
What happens when a hydrogen atom with a charge of plus 1 comes in contact with a chlorine atom with a charge of-1?
HCl is formed.
