It includes reactions where new molecules are synthesized, It includes reactions where molecules are broken down, It can be defined as the sum of all the chemical reactions in the body, It only takes place in actively contracting cells, It always requires an input of energy
what type of joint did Torin injure? What is the range of motion of this joint?
Joint and its ‘Range of Motion’ ‘Torin’ has been injured by the ‘Dislocation of the shoulder’. (1) This is a well known fact thatthere might be two types of ‘dislocations’ in case…
Electrospray ionization mass spectrometry (ESI-MS) of a cytochrome c yielded two successive (adjacent) peaks with m/z values of 1365.76 (p1) and 1516.40 (p2). Calculate the mass of this cytochrome c based on these data. Remember that the measured m/z values of two adjacent peaks (p1 and p2) arise from ions with charges z1 and z1-1 (p1 and p2 differ by a single proton with p2 having one fewer positive charge due to its higher m/z value): (1) p1 = (M + z1)/z1 and (2) p2 = (M + z1 – 1)/(z1 – 1)
I got the following correct, but I am assuming it is an E2 reaction. However, I don’t understand this because my chart indicates that an E2 reaction requires a strong base and I don’t see how (CH3)3COH is a strong base. Where am I confused at?
A person wears a hearing aid that uniformly increases the sound level of all audible frequencies of sound by 24.3 dB. The hearing aid picks up sound having a frequency of 250 Hz at an intensity of 2.90 10-11 W/m2. What is the intensity delivered to the eardrum?
PROBLEM 3: The AC generator in the picture below supplies the maximum emf ℇ0 at the frequency
PRQBLEM 3: The AC generator in the picture below supplies the maximum emf En atthe frequency 1‘. With the switch in the open position {show in the picture} the resultingcurrent leads the generator emf by an angle in]. When the switch is moved to position 1,the resulting current lags the generator emf by an angle rpi. When the switch is moved toposition 2, the maximum current is f2. ”T1 {a} Determine the ualues of R, L, and E in terms of the giuen variables.
Two tugboats pull a disabled supertanker. Each tug exerts a constant force of 1.60×106 rm N, one at an angle 19.0^circ west of north, and the other at an angle 19.0^circ east of north, as they pull the tanker a distance 0.610 rm km toward the north What is the total work done by the two tugboats on the supertanker?
A 66.0 kg person throws a 0.0400 kg snowball forward with a ground speed of 27.0 m/s. A second person, with a mass of 59.0 kg, catches the snowball. Both people are on skates. The first person is initially moving forward with a speed of 2.50 m/s, and the second person is initially at rest. What are the velocities of the two people after the snowball is exchanged? Disregard the friction between the skates and the ice.
You measure water in two containers: a 10-mL graduated cylinder with marks at every mL, and a 1-mL pipet marked at every 0.1 mL. If you have some water in each of the containers and add them together, to what decimal place could you report the total volume of water?
