V = (1 / p) × p0 × V0
1 / p = V / (p0 × V0)
p = (p0 × V0) / V = (49kPa × 11L) / 4L = 134.75kPa
ANSWER:
basically a mixture is when two or more substance combine WITHOUT making a new substance.
so your answer is the last one D.mixtures are classified based on the distribution of particles in them

The farthest planet from Pluto in our solar system would be Mercury.
That is because Mercury is nearest the sun, while Pluto is farthest from the sun.
But keep in mind that Pluto is a dwarf planet, and it isn't considered as a planet in our solar system.
Answer:
Explanation:
a ) starting from rest , so u = o and initial kinetic energy = 0 .
Let mass of the skier = m
Kinetic energy gained = potential energy lost
= mgh = mg l sinθ
= m x 9.8 x 70 x sin 30
= 343 m
Total kinetic energy at the base = 343 m + 0 = 343 m .
b )
In this case initial kinetic energy = 1/2 m v²
= .5 x m x 2.5²
= 3.125 m
Total kinetic energy at the base
= 3.125 m + 343 m
= 346.125 m
c ) It is not surprising as energy gained due to gravitational force by the earth is enormous . So component of energy gained due to gravitational force far exceeds the initial kinetic energy . Still in a competitive event , the fractional initial kinetic energy may be the deciding factor .
Answer
given,
mass of satellite = 2400 Kg
speed of the satellite = 6.67 x 10³ m/s
acceleration of satellite = ?
gravitational force of the satellite will be equal to the centripetal force
Assuming the radius of circular orbit = 8.92 x 10⁶ m
now,
F = 11970.11 N
acceleration,
a = 4.98 m/s²
