Is ice made of H2O?

Is ice made of H2O? Ice is H2O. c. Water vapor is H2O Adam Sennet has no problem with this. Water is a liquid. Can you have water vapor at 0 C? Yes, water can stay liquid below zero degrees Celsius. There are a few ways in which this can happen. The freezing point of […]

What is the largest group of rock-forming minerals?

What is the largest group of rock-forming minerals? Silicates What are the two main group of minerals? All minerals, however, can be classified into two main groups—silicate minerals and nonsilicate minerals—based on the chemical compositions of the minerals. What are the 7 mineral groups? Silicates, oxides, sulfates, sulfides, carbonates, native elements, and halides are all […]

What does a constant velocity graph look like?

What does a constant velocity graph look like? Constant velocity means the velocity graph is horizontal, equal to 11.11 m/s at all times. A constant velocity means the position graph has a constant slope (of 11.11 m/s). It’s a straight line sloping up, and starting below the origin. The displacement is the area under the […]

Is it worth it to buy a telescope?

Is it worth it to buy a telescope? Most telescopes that cost less than $300 aren’t really worth it. We suggest getting good binoculars instead. Stay away from any telescope advertised for its magnifying power. For a child, look for a tabletop telescope that’s portable, easy to push around the sky, and virtually indestructible. What […]

How do you calculate your weight on Neptune?

How do you calculate your weight on Neptune? Being that it takes the weight of an object on earth and converts it to the weight on Neptune, the formula is Weight on Neptune= (Weight on Earth/9.81m/s2) * 11.15m/s2. To find the weight on Neptune, we divide the weight on earth by the earth’s force of […]

What are two ways to determine energy expenditure?

What are two ways to determine energy expenditure? Energy expenditure can be estimated by measuring macronutrient or oxygen consumption, or heat production or carbon dioxide production. Most measurement approaches in use today involve the measurement of oxygen consumption and/or production of carbon dioxide via indirect calorimetry. What are the components of energy expenditure? Total energy […]

Why gravity is always attractive?

Why gravity is always attractive? In the case of gravity, mediated by spin 2 particles, charge is mass, which is always positive. Thus, q1q2 is always greater than zero, and gravity is always attractive. For spin 0 force mediators, however, there is no restriction on the charges and you can very well have repulsive forces. […]
