Answer:

Option A. 500

Explanation:

From the question given, we obtained the following:

Numbers of home with pet dogs = 250

Percentage with pet dogs = 50%

Total number of homes =.?

Thus, we can obtain the total number of homes represented by the chart as follow:

Let T be the total number of Homes.

Number of homes with dog = percentage of homes with dog × total number

Numbers of home with pet dogs = 250

Percentage with pet dogs = 50%

Total number of homes = T

250 = 50% × T

Divide both side by 50%

T = 250 ÷ 50%

T = 250 ÷ 50/100

T = 250 × 100/50

T = 250 × 2

T = 500

Therefore, the total number of homes represented by the chart is 500.

Answer:

newton's 2nd law

Explanation:

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

The pet store would be the reference point because it is where he started and it will not move. Hope this helped.

Answer: 96N

Explanation:

To calculate the velocity of the impact On the persons head, we have

h = gt²/2

14 = 9.81t²/2

t² = 28/9.8

t² = 2.86

t = 1.69s

V = u + at

V = 0 + 9.81*1.69

V = 16.58m/s

a(average) = (v1² + v2²) /2Δy

a(average) = 16.58² + 0)/2 * 0.005

a(average) = 274.8964/0.01

a(average) = 27489.64m/s²

Using newton's second law of motion,

F(average) = m * a(average)

F(average) = 0.0035 * 27489.64

F(average) = 96.21N

Therefore the force needed by the acorn to do much damage starts from 96N

Humans evolved in Earth's atmosphere, therefore the pressures interior to the body are relatively close to atmospheric pressure.

harina [27]

Answer:

194516 sheets

Explanation:

So the area of each sheet of paper is:

A = 0.216 * 0.279 = 0.060264 square meters

For the paper sheet to make the same effect as the atmospheric pressure P, then the gravity F from the paper sheet must be

F = AP = 0.060264 * 101325 = 6106 N

Let g = 9.81 m/s2, then the mass of paper needed to generate that gravity is

m = F/g = 6106 / 9.81 = 622.4 kg

If each sheet has a mass of 0.0032 kg, then the total number of sheets to have that much mass is

622.4 / 0.0032 = 194516 sheets
