Answer:

So first determine how many times does 5 go into 100.

100/5=20

Thus in 100 seconds the boy would have traveled a distance of 10 meters 20 times.

10*20=200

If the boy travels 10meters in 5 seconds, he travels 200m in 100seconds.

Here, we know that the the total distance is 10m and the total time is 5s . so the avg. speed is 10m5s=2m/s .

If this helped please give me brainliest!

A current of 0.2 A flows through a conductor for 5minutes. How much charge would have passed through the conductor?

Montano1993 [528]

As we know,

$electric \: \: current = \dfrac{charge}{time}$

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

time = 5 minutes = 5 × 60 seconds = 300 seconds.

$0.2 = \dfrac{q}{300}$

$q = 300 \times 0.2$

$q = 60$

hence, the charge = 60 coulombs (C)

Given that: = 2i + 9j ; and ⃗ = -i – 4j . Find . ⃗

Marat540 [252]

Answer:

A.B = -38

Explanation:

A = 2i + 9j and B = -i - 4j.

So, A.B = (2i + 9j).(-i - 4j)

= 2i.(-i) + 2i.(-4j) + 9j.(-i) + 9j.(-4j)

= -2i.i - 8i.j - 9j.i - 36j.j

since i.i = 1, j.j = 1, i.j = 0 and j.i = 0, we have

A.B = -2(1) - 8(0) - 9(0) - 36(1)

A.B = -2 - 0 - 0 - 36

A.B = -38

Alex hope in her parked car, turns the key, and slams on the gas, producing an acceleration of 4.8m/s2. If she does this for 4,4

Maksim231197 [3]

Answer:

She has travelled 46.46 meters

Explanation:

Step 1: Data given

The car starts from rest so v0 = 0 m/s

Acceleration a = 4.8 m/s²

Time travelled = 4.4 seconds

Step 2: Calculate the distance

Since this is an acceleration we will use the formula X = 1/2 * at² +v0t + x0

with X = the total distance travelled

with x0 = the start point ( in this case it's 0)

with a = the acceleration ( in this case 4.8 m/s²)

with v0 = the initial speed ( in this case 0 m/s)

with t= the time travelled (in this case 4.4s)

X = 1/2 * 4.8 m/s² * (4.4s)² + 0*4.4s + 0

X = 1/2 * 4.8 m/s² * (4.4s)²

X = 46.46 m

She has travelled 46.46 meters
