The work needed to pump the water would have the units of Joules or Pa*m^3. From here, this would be a hint that you only multiply the hyraulic pressure and its volume.
Hydraulic pressure = density*gravity*height = 1000*9.8*3.1 = 30,411 Pa
Volume = 21*14*3.1 = 911.4 m^3
Work = 30,411*911.4 = 27,716,585.4 J = 27.72 MJ
Answer:
an unconventional magnetic material that consists of organic molecules, coordination compounds, or combinations. Single-molecule magnet, a single molecule that exhibits magnetic hysteresis of itself, without collective long-range ordering.
Explanation:
Answer:
1.3 g/cm³
Explanation:
The mass of the paint without the tin or lid is:
7 kg − 0.5 kg = 6.5 kg = 6500 g
Density is mass per volume:
d = 6500 g / 5000 cm³
d = 1.3 g/cm³
Answer:
11.2°
Explanation:
Using the trigonometry ratio,
Note: Assuming the ladder, the wall and the horizontal forms a right angle triangle.
Cosθ = Opposite/Hypotenuse
SinΦ = O/H.......................... Equation 1
Where Φ = angle between the ladder and the wall, O = opposite, H =Hypotenuse.
make Ф the subject of the equation,
Ф = sin⁻¹(O/H).................. Equation 2
Given: O = 3.3 foot, H = 17 foot
Ф = sin⁻¹(3.3/17)
Ф = sin⁻¹(0.194/
Ф = 11.19°.
Ф = 11.2° ( to the nearest tenth degree)
Hence the ladder and the wall makes an angle of 11.2°
Answer:
Explanation:
The time taken by the light to travel a given distance is defined as:
Here c is obviously the speed of light. Now we convert the average distance form Venus to Earth to meters:
Finally, we calculate the minutes taken by the light to travel from Venus to Earth:
