Answer:

Density of the mixture = 855.56kgm-3

Explanation:

Density = Mass / Volume

Volume of Liquid X = 0.5m³

Density of Liquid X = 900kgm-3

Mass of Liquid X = Density × Volume

= 900kgm-3 × 0.5m³ = 450kg

Volume of Liquid Y = 0.4m³

Density of Liquid Y = 800kgm-3

Mass of Liquid Y = Density × Volume

= 800kgm-3 × 0.4m³= 320kg

As X and Y are mixed, we add their masses and volumes together:

Mass = 770kg

Volume = 0.9m³

Now we can find the density of the mixture:

Density = 770kg / 0.9m³ = 855.56kgm-3 (rounded to the 2nd decimal)

What is friction ??? ​
jeka94

Answer:

Frictional force is produced when two bodies are rubbed against each other. It is the force that oppose the motion and therefore it stops or slow down a moving body.It depends upon the roughness or smoothness of the surface of the body in contact.Rough surface have more friction that the smooth surface. Similarly, the heavier body produces more friction than a lighter body. Frictional force acts in the opposite direction of the motion of the body.

The auroras occur in the
kotykmax [81]

Answer:

Ionosphere

Explanation:

The thermosphere reaches 600 kilometres just above mesosphere and begins immediately above the mesosphere. This layer is where the aurora and satellites appear.

The ionosphere is the comprehensive career of the mesosphere because most of the thermosphere, located 80–400 kilometres just above ground atmosphere.

Auroras — magnificent flowing streaks of light seen in the night sky – appear in this location.

A mirrored-glass gazing globe in a garden is 28.0 cm in diameter. part a what is the focal length of the glob
olga nikolaevna [1]
For a curved mirror, the radius of curvature R is twice the focal length f:
R=2f (1)
Since the diameter d is twice the radius R, we can rewrite (1) as
\frac{d}{2} = 2f
From which we can calculate the focal length from the diameter:
f= \frac{d}{4}= \frac{28.0 cm}{4}=7.0 cm

A human being can be electrocuted if a current as small as 50 mA passes near the heart. An electrician working with sweaty hands
Dovator [93]

Answer:

The fatel voltage is 100 volts.                              

Explanation:

Given that,

Current passes near the heart is, I=50\ mA

An electrician working with sweaty hands makes good contact with the two conductors he is holding, one in each hand.

Resistance, R = 2000 ohms

We need to find the fatal voltage. It can be calculated using Ohm's law as :

V=IR\\\\V=50\times 10^{-3}\times 2000\\\\V=100\ V

So, the fatel voltage is 100 volts. Hence, this is the required solution.
