You finally decide to take some liquid nitrogen from the physics lab and freeze the 1.5 pounds of beans which were sitting in your vegetable basket at 20 c, rather than cook and eat them as your mother would have you do. beans are mostly water, like all living things. if the specific heat of water is approximately 1 cal/g/c and latent heat of fusion of water is approximately 80 cal/g, and the latent heat of vaporization of liquid nitrogen is 45 cal/g as measured by you, how much liquid nitrogen should you take from the lab (approximately)? you don't want to take a whole lot more than you really need.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
