Answer:
13.524 N
Explanation:
Volume and densities are given as:
ρ1 = 2.6 g/cm³ => 2600 kg/m³ ; V1 = 0.50 L => 0.5 x 10^-3 m³
ρ2 = 1.0 g/cm³ => 1000 kg/m³ ; V2= 0.25 L => 0.25 x 10^-3 m³
ρ3 = 0.7 g/cm³ => 700 kg/m³ ; V3 = 0.4 L => 0.4 x 10^-3 m³
Next is to calculate force exerted on the bottom of the container due to these liquids:
F= ρ1V1g + ρ2 V2 g+ ρ 3 V3g
where ,
ρ= density
V= volume
g= 9.8m/s²
F= g( 2600 x 0.5 x 10^-3 + 1000 x 0.25 x 10^-3 + 700 x 0.4 x 10^-3)
F= 9.8 (1.38)
F= 13.524 N
Therefore, the force on the bottom of the container due to these liquids is 13.524 N
You can think of a magnet<span> as a bundle of tiny </span>magnets<span>, </span><span> that are jammed together. Each one reinforces the </span>magnetic<span> fields of the others. Each one has a tiny north and south pole. </span>If you cut<span> one in </span>half<span>, the newly </span>cut<span> faces will become the new north or south poles of the smaller pieces.

So the answer is D
Answer:
The length of the trail = 22796 ft
Explanation:
From the ΔABC
AC = length of the trail = x
AB = 6100 - 600 = 5500 ft
Angle of inclination 
= 15°
x = 22796 ft
Since x = AC = Length of the trail.
Therefore the length of the trail = 22796 ft
Answer:
The longest wavelength of light is 209 nm.
Explanation:
Given that,
Spring constant = 74 N/m
Mass of electron 
Speed of light 
We need to calculate the frequency
Using formula of frequency
Where, k= spring constant
m = mass of the particle
Put the value into the formula
We need to calculate the longest wavelength that the electron can absorb
Where, c = speed of light
f = frequency
Put the value into the formula
Hence, The longest wavelength of light is 209 nm.
