Levart [38]

Answer:

1260

Step-by-step explanation:

Round 0.65 to 0.7 and round 1754 to 1800. To get 1260, I recommend an easy way to do this. I would take 18 and multiply it by 7, giving us 126. Because it was supposed to be 0.7, not 7, we multiply by 10 because 7/10 is 0.7. This gives us 126 times 10 which equals 1260.

The force of repulsion, F Newton (N).,between particles is invesrly propotional to the square of the distance dm1find the partic

Fynjy0 [20]

Answer:

$F_{2} = 80\,N$

Step-by-step explanation:

Given the consideration of the inverse proportionality between force and distance, the following relationship is constructed and described below:

$F_{1}\cdot r_{1}^{2} = F_{2}\cdot r_{2}^{2}$

The force when the distance is halved is:

$F_{2} = F_{1}\cdot \left(\frac{r}{0.5\cdot r} \right)^{2}$

$F_{2} = 4\cdot F_{1}$

$F_{2} = 4\cdot (20\,N)$

$F_{2} = 80\,N$

The Blackburn family has a square fold where they keep their cattle.The area of the field is 40,000ft square, and Mr. Blackburn

grandymaker [24]

Answer: Length of fence along the diagonal is 28.3 feet.

Step-by-step explanation:

Since we have given that

The Blackburn family has a square field ,

Area of square = 40000 ft square

As we know the formula,

Area of square = Side x Side

40000 = slide ${2}$

$\sqrt 40000\\$

20 ft = Side

But Blackburn wants to put a fence diagonally through the field ,

As we know the formula for "Diagonal of side" i.e.

Diagonal of square $\sqrt2Slide$

Diagonal of square 20 $\sqrt2$

So,

Length of fence along the diagonal = 20 x 1.41 = 28.3

Hence, length of fence along the diagonal is 28.3 feet.

Hope this helps!

13 km = ? m ???????????????

zhenek [66]

Answer:

13 Kilometers = 13000 meters

Step-by-step explanation:

Using the conversion:

1 kilometers = 1000 m

We can find how much meters are in 13 km.

=> 13 Kilometers = 1000 x 13

=> 13 Kilometers = 13000 meters

Therefore, in 13 kilometers, there is 13000 meters.

Hoped this helped.
