Answer:
281.6 K
Explanation:
The speed of sound in an ideal gas is given by c = √(γKT/m).
From the question speed of sound in Ne, c₁ = 2c₂ speed of sound in Kr
c₁ = √(γKT₁/m₁) and c₂ = √(γKT₂/m₂)
So √(γKT₁/m₁) = 2√(γKT₂/m₂) where T₁, m₁ and T₂, m₂ are the temperatures and atomic masses of Neon and Krypton respectively.
So, √(T₁/m₁) = 2√(T₂/m₂)
(T₁/m₁) = 4(T₂/m₂) (squaring both sides)
T₁ = 4(T₂m₁/m₂)
Given that m₁ = 20.2 u , m₂ = 83.8 u, T₂ = 292 K
T₁ = 4(292 × 20.2/83.8) K = 23593.6/83.8 = 281.55 K ≅ 281.6 K
Answer:
Energy is the strength and vitality required for sustained physical or mental activity.
Matter occupies space and possesses rest mass, especially as distinct from energy.

Answer:
the force needed to give the truck the acceleration is 29,760 N.
Explanation:
Given;
mass of truck, m = 4800 kg
acceleration of the truck, a = 6.2 m/s²
The force needed to give the truck the acceleration is calculated as;
F = ma
F = 4800 x 6.2
F = 29,760 N
Therefore, the force needed to give the truck the acceleration is 29,760 N.
Acceleration of car is 4m/s²
Acceleration of truck is 2m/s²
Explanation:
Given parameters:
Force on the car and truck = 12000N
Mass of car = 3000kg
Mass of truck = 6000kg
Unknown:
Acceleration of car = ?
Acceleration of truck = ?
Solution:
Force is product of mass and acceleration. It is a push or a pull exerted on a body.
Force = mass x acceleration
Make acceleration the subject of the formula;
Acceleration = 
Acceleration of car = 
= 4m/s²
Acceleration of truck = 
= 2m/s²
