Answer:
Conduction occurs when two objects at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature. ... It is caused by the increased activity or speed of molecules in a substance, which in turn causes temperature to rise accordingly. This process continues until heat energy from the warmer object spreads throughout the cooler object.

Answer:
Force,F =
Explanation:
Given that,
Charge 1,
Charge 2,
Negative charge is 0.002 m north of a positive charge, distance between charges, d = 0.002 m.
Let is the magnitude of electrical force applied by q₁ on q₂. We know that the electrical force is given by the formula as follows :
So, the electrical force applied by q₁ on q₂ is towards north.
Answer:90.3 kg
Explanation:
Given
Mass of astronaut
Initial velocity of canister
Final velocity of canister
Final speed of Astronaut
let M be the mass of canister
As there is no external force therefore we can conserve momentum
Answer:
The force is inversely proportional to the square of radial distance and the mass of the lemon is compensated.
Explanation:
- It is true that our body is composed mostly of water (precisely 75% of the body mass) which is influenced by the gravitational forces. This gravitational force in the water bodies cause tides.
We know that mathematically gravitational force is given as:
where:
R = radial distance between the masses
we observe that:
The force is inversely proportional to the square of radial distance.
- And the radial distance between the moon and a human on the earth is much greater than the distance between a lemon of low mass on the head of a human.
