A proton is located at <3 x 10^-10> m. What is r, the vector from the origin to the location of the proton
Eduardwww [97]

Complete Question

A proton is located at <3 x 10^{-10}, -5*10^{-10}  , -5*10^{-10}> m. What is r, the vector from the origin to the location of the proton

Answer:

The  vector position is   \=r=

Explanation:

From the question we are told that

  The  position of the proton is m

Generally the vector location of the proton is mathematically represented as

       \= r =

So substituting values

     \=r=

A current of 0.8 A flows through the motor for 3 minutes. Calculate the total charge in this time.
mixas84 [53]

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

The given terms are :

Current = 0.8 Amperes

Time = 3 minutes = 3 × 60 = 180 seconds

we know that,

  • current =  \dfrac{charge}{time}

now, let's solve for charge (q) :

  • 0.8 =  \dfrac{q}{180}

  • q = 180 \times 0.8

  • q = 144 \:

Total Charge (q) = 144 Coulombs

How much force is needed to stop a 80 kg football player if he decelerates at 5m/s?
cricket20 [7]

Use Newton's 2nd law of motion.
Here it is:

                     Force  =  (mass)  x  (acceleration)

                                 = (80 kg) x (-5 m/s²)

                                 =      -400 Newtons .

I called the acceleration negative because the player is slowing down.

The force comes out negative because it's in the direction opposite to
his motion.
