Explain why condensatin forms on a glass containing a cold drink.
Only so much water vapor can be in the air at any temperature, and at cooler temps the air holds less. Air is very cold near the surface of the glass.
hi plz help me i whant some information about teeth for my home work not for me i have beautifull white teeth but i don't know about teeth so plz help me !xxx
how are an objects mass and weight different?
An object's mass and weight are two different physical quantities that are often confused with one another.
Mass refers to the amount of matter present in an object. It is a measure of how much "stuff" is in an object and is typically measured in units like grams or kilograms. The mass of an object remains the same regardless of its location in the universe.
Weight, on the other hand, refers to the force with which an object is pulled towards the center of the Earth (or any other celestial body). It is influenced by both the mass of the object and the strength of the gravitational field it is in. Weight is calculated using the equation W = mg, where W is the weight, m is the mass, and g is the acceleration due to gravity.
To put it simply, mass is an intrinsic property of an object that remains constant, while weight depends on the gravitational field and will change if the object is moved to a different location in the universe.
To find the weight of an object, you need to know the mass of the object and the acceleration due to gravity in that specific location. Gravity on Earth is relatively constant, so the weight of an object can be calculated using the equation W = mg, where m is the mass of the object and g is the acceleration due to gravity, approximately 9.8 m/s².
On other planets or celestial bodies, the acceleration due to gravity may be different, leading to a different weight for the same mass. For example, an object with a mass of 10 kg on Earth would weigh approximately 98 newtons (N), while on the Moon where gravity is about 1/6th of that on Earth, the same object would weigh approximately 16.3 N.
