A skateboarder travels on a horizontal surface with an initial velocity of 4.0 m/s m / s toward the south and a constant acceleration of 2.5 m/s2 m / s 2 toward the east. Let the x x direction be eastward and the y y direction be northward, and let the skateboarder be at the origin at t=0 t = 0 .

explanation:

the masses of the objects and the distance between them

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

lol

explanation:

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
