Gold is much heavier because it has a greater density, meaning the atoms are more closely packed. Also, the individual atoms are heavy as well making 1g of gold heavier than 1g of aluminum.
Answer:
Explanation:
If Tim jogs a distance of 7.2 km to the west and then he turns south and jogs 1.4 km, the resultant displacement of Tim is calculated using the pythagoras theorem as shown;
R² = 7.2²+1.4²
R² = 51.84+1.96
R² = 53.8
R = √53.8
R = 7.33 km
Hence the resultant of Tim's jog back to the beginning is 7.33km
Uh i think you need to show me the material one and material 2?
Answer :
New force becomes, F' = 1.83 N
Explanation:
Let two point charges exert a force of 7.35 N force on each other. The electric force between two charges is given by :

are charges
r is the distance between charges if the distance between them is increased by a factor of 2, r' = 2r
New force is given by :




F' = 1.83 N
So, the new force between charges will be 1.83 N. Therefore, this is the required solution.
