Answer:
Explanation:
Saturn orbital period
p(s)= 29.46years
Average distance
a(s) = 9.54AU
Venus orbital period
p(v) = 0.62 years
a(v) ?
Using Kepler's third law
a³ ∝p²
a³ = kp²
a³/p² = k
Where
a is the distance if planet from sun
T is the period of the planet
Then,
a(Venus)³/p(venus)² = a(saturn)³/p(saturn)²
a(v)³/p(v)² = a(s)³/p(s)²
a(v) ³/ 0.62² = 9.54³/29.46²
a(v) ³/ 0.62² = 1.0004
a(v)³ = 1.0004× 0.62²
a(v)³ = 0.3846
a(v) = cube root(0.3846)
a(v) = 0.727 AU

INCREASE in temperature of the material practically increase the energy of the particles. which increases their motion due to increase in energy . thus when the temperature is decreased the energy level decreases which causes the particle's motion to slow down.. the motion of the particle is highly reduced when the temperature is lowered
Answer:
The mass of the body is 2.2 kg.
Explanation:
Given that,
Force acting on a body 1,
Force acting on a body 2,
Direction,
Acceleration,
To find,
Mass of the body.
Solution,
Let F is the net force acting on the body. It is given by :
F = 43.22 N
Second law of motion is given by :
F = ma
m = 2.16 kg
or
m = 2.2 kg
So, the mass of the body is 2.2 kg.
