The material is made of carbon composite since the density of this material is similar to the drone
<h3>What is density?</h3>
Density is mass per unit volume. It is is an important property of a material that helps in saying other features of the material. It also says substance that has more weight as a highly dense substance will have more weight when compared with a less dense substance.
<u>Given data</u>
Initial volume of water = 1000ml
the drone displaced the water to 2290 ml
mass of the drone = 2 kg = 2000 g
<h3>Density of the drone</h3>
volume of the drone equals the volume of water displaced
2290 ml - 1000 ml = 1290 ml
density in g/cm*3
= mass / volume
= 2000 / 1290
= 1.550 g/ml
The density of the drone is similar to density of carbon composite hence the drone of made of carbon composite

The decimal 0.3 can be written as 3/10.
Answer:
3.14 cm
Step-by-step explanation:
From the question,
Applying
s = πdФ/360................... Equation 1
Where s = length of arc AB, d = diameter of the circle, Ф = angle at the center of the circle, π = pie
From the question,
Given: d = 8 cm, Ф = π/4 rad = 45°
Constant: π = 22/7
Substitute these values into equation 1
s = (22/7)(8)(45)/360
s = 3.14 cm.
Hence the lenght of arc AB = 3.14 cm
Answer:
B) 47.5%
Step-by-step explanation:
Refer to the normal distribution chart attached. If 130 is 2 standard deviations higher than the mean (ignore the numbers beneath the percentages), then by the empirical rule, this means that 34%+13.5%=47.5% of adults are between IQs of 100 and 130. Therefore, option B is correct.
Answer:
32 cm^3
Step-by-step explanation:
The cube is 4 across by 4 high by 2 wide
4*4*2 = 32 cm^3
