Help pls I’ll give extra points

Mathematics
1 answer:
n200080 [17]3 years ago
3 0

Answer:

A

Step-by-step explanation:

Let's go by process of elimination.

Two negatively charged objects will repel each other because they are the same charge, and like repels like. Opposites attract. Same principle for B.

For D, this is true because as the charge decreases, so does the strength of the force between the two objects. This is why you can push two weak magnets that have the same polar sides together, and why you can't with a stronger one.

This leaves us with A, and A is not true because force is inversely proportional to distance, and so if the distance is larger, the force is smaller, and if the distance is smaller, the force is larger. Like how 1/3 is bigger than 1/9.

the length, breadth and height of a cuboid are in the ratio 5:4:2 if the volume of cuboid is 5000 cm,then what will be the surfa
Sonbull [250]

Answer:

  1900 cm²

Step-by-step explanation:

We can use the given ratios and volume to find the scale factor for the dimensions. Knowing the dimensions, we can compute the surface area using the formula for a cuboid.

__

<h3>dimensions</h3>

Let k represent the scale factor. Then the actual dimensions will be 5k, 4k, and 2k. The actual volume will be ...

  V = LWH

  5000 cm³ = (5k)(4k)(2k) = 40k³

  k³ = (5000 cm³)/40 = 125 cm³

  k = ∛(125 cm³) = 5 cm

The cuboid dimensions are 5(5 cm) = 25 cm, 4(5 cm) = 20 cm, and 2(5 cm) = 10 cm.

__

<h3>area</h3>

The surface area of the cuboid can be computed from ...

  A = 2(LW +H(L +W))

  A = 2((25 cm)(20 cm) +(10 cm)(25 +20 cm))

  A = 2(500 cm² +(10 cm)(45 cm)) = 2(950 cm²) = 1900 cm²

The surface area of the cuboid is 1900 cm².

A father is 60 years old and his son is half his age. How old was the boy when his father was four times his age?
Komok [63]
So, if the father is 60, his son is half his age, which would be 30.

So, to find out how old the boy was when his father was 4 times his age, you would do, 30 divided by 4 (I believe).

You then should get, 7 1/2 years old the boy is.

Hope this helps! Have a great rest of your day! c:
