What are all the possible combinations of 3 numbers 0 9? What are all the possible combinations of 3 numbers 0 9? There are 3 digits, each digit as 10 different possible answers, 0, 1, 2, 3, 4, 5, 6, 7, 8, & 9. In a probability problem, you multiply these 10 different possibilities by […]

Can a body have zero velocity and finite acceleration? This acceleration is the gravitational acceleration. At that point the component of acceleration/gravitational acceleration works there. So, at the topmost point the velocity is zero but acceleration is not and has a finite value. Therefore, a body can have zero velocity and finite acceleration. Is it […]

What is order of magnitude give example? The order of magnitude is the power of 10 a number is raised to when it’s in scientific notation. For example, the order of magnitude for 19,400 would be 4. We can say C is two orders of magnitude larger than A. Also, C is ten times the […]

What was the first train called? On September 27, 1825, Locomotion No. 1 became the world’s first steam locomotive to carry passengers on a public line, the Stockton and Darlington Railway, in North East England. Locomotion No. 1 was built by George Stephenson at his son Robert’s company, the Robert Stephenson and Company. How fast […]

What does rotational inertia depend on? mass What happens when rotational inertia increases? Objects with mass require forces to make them speed up or slow down because they have inertia. An object with more rotational inertia is harder to accelerate. Any object with mass will have rotational inertia, and this makes it harder to speed […]

What is it called when you say something to make it happen? catalyze. verb. to cause something to happen, especially in way that involves a lot of change. What is it called when you make yourself believe? When a person, who disbelieves p, intentionally tries to make himself believe or continue believing p by engaging […]

Why do grasshoppers live in grass? Grass. Grasshoppers are drawn to patches of grass for several key reasons, chiefly because it is a main source of nutrition for them. They also lay their eggs in the soil under the grass, which is why your green carpet of lawn is an ideal spot for these winged […]

How do you calculate the effusion of a gas? From Graham’s law, we can use the molar mass of each gas: rate of effusion of hydrogenrate of effusion of oxygen=√32g mol−1 √2g mol−1 =√16√1=41 rate of effusion of hydrogen rate of effusion of oxygen = 32 g mol − 1 2 g mol − 1 […]

What hormones do males and females have in common? Generally, females and males have the same hormones (i.e., estrogens, progesterone, and testosterone), but their production sites, their blood concentrations, and their interactions with different organs, systems, and apparatus are different [29]. What hormone does both sexes produce? Testosterone is produced by the gonads (by the […]
