Answer:
Convection
Explanation:
The method of heat transfer that occurs when particles move through a fluid is called convection.
Conduction is where heat is transferred from one substance to another through direct contact.
Thermal energy is the amount of heat that a substance has.

Answer:
10 kg.m/s
Explanation:
Momentum is a product of mass and velocity, expressed as p=mv where m is the mass of an object, v is the velocity of an object and p denote momentum.
The principle of linear momentum states that the sum of momentum before and after collision are always equal.
Given mass of initially as 2kg and its velocitu as 5kg and taking forward direction as positive.
Momentum before collision will be
P=2kg*5m/s=10 kg.m/s
The Sun is 864,400 miles across. its about 109 times the diameter of Earth<span>. so the volume is about 109 times the volume of the earth.</span>
Answer:
the chemical reaction will be fire and smoke
(2)(3)(2)=12⇒ D=M/V ⇒ D=94/12=7.8333(repeated) g/m³
