The gearshift lever AB for the transmission of a sports car has position vector $\vec{r}$ whose line of action passes through points A and B. The driver applies a force $\vec{F}$ to the knob of the lever to shift gears. If the component of $\vec{F}$ perpendicular to the gearshift lever must be 5.5 N to shift gears, determine the magnitude F of the force. (Round the final answer to four decimal places.) $\vec{r} = (-5\vec{i} + 2\vec{j} + 14\vec{k})$ mm $\vec{F} = F(\frac{1}{11})(9\vec{i} - 6\vec{j} - 2\vec{k})$ The magnitude F of the force is [ ] N.

Biology II Dr. Irene Matejko Chapter 25- Lab and HW Assignments HW Assignment #1 - Lab "When Can Half a Clock Tell Time?" Introduction: Radioactive Isotopes - decay (break-down) into more stable form and during the decay they give off alpha, beta, and gamma particles that are emitted from the atoms and interferes with DNA and Mitosis in the human body Stability of a Radioactive Isotope is measure by its Half-Life. This is the time it takes for one half of the atoms in a radioactive material in a sample to decay. It takes approximately 10 times its half-life for the sample of a radioactive isotope to decay to 1-life for safe levels. Radioactivity is measured in: 1. Rad - radiation absorbed dose or 2. Rem - radiation equivalent to man Problem: How does half life relate to the amount of original element that remains? Procedure: Use the following data to determine how long it would take a radioactive element to break to a non-radioactive element and write the time on the line provided. 1. Carbon -14 has a half life of 5730 years. How long will it take to dissipate into a non-radioactive element? 2. Uranium - 238 has a have life of 4.5 billion years. How long will it take to dissipate into a non-radioactive element? 3. Potassium - 40 has a half life of 1.3 billion years. How long will it take to dissipate into an non-radioactive element? viles 4. Nitrogen -16 has a half life of 8 seconds. How long will it take to dissipate into a non-radioactive element? 5. Bromine-85 has a half life of 3 minutes. How long will it take to dissipate into a non-radioactive element? 6. Sodium-24 has a half life of 14.8 hours. How long will it take to dissipate into a non-radioactive element?

There is a 0.9989 probability that a randomly selected 32-year-old male lives through the year. A life insurance company charges $145 for insuring that the male will live through the year. If the male does not survive the year, the policy pays out $90,000 as a death benefit. Complete parts (a) through (c) below. a. From the perspective of the 32-year-old male, what are the monetary values corresponding to the two events of surviving the year and not surviving? The value corresponding to surviving the year is $ The value corresponding to not surviving the year is $ (Type integers or decimals. Do not round.) b. If the 32-year-old male purchases the policy, what is his expected value? The expected value is $ (Round to the nearest cent as needed.) c. Can the insurance company expect to make a profit from many such policies? Why? because the insurance company expects to make an average profit of $ on every 32-year-old male it insures for 1 year. (Round to the nearest cent as needed.)

A particle of mass M is moving in the positive x direction with speed v. It spontaneously decays into 2 photons, with the original particle disappearing in the process. One photon has energy 233 MeV and moves in the positive x direction, and the other photon has energy 21 MeV and moves in the negative x direction. Find the mass M of the particle, in units of MeV/c2
