You find yourself on the number line again. The numbers are still spaced at 1 meter. Starting at zero, you decide to take 75 seconds to walk. You go to +7, +2, +11, -5, 0, -10, and finally -2. What is your distance, displacement, speed, and velocity?

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
