Answer:
Equivalent Resistance of Resistors in Parallel is
1/R = 1/r1 + 1/r2 .....
1/R = 1/7 + 1/7 + 1/7
R= 7/3
R=2.33ohms

Explanation:
I disagree with my friend because, the primary difference is not in the kind of atoms, rather it is the arrangement of atoms and molecules that distinguishes solids and liquids.
Atoms are closely packed in solid and hence large cohesive forces act between atoms in solids whereas in liquids atoms are at a distance from each other, hence, less cohesive force act between it's atoms. Moreover, due to loose packing in liquids atoms are free to move in space and hence liquids can flow whereas solids cannot.
The skateboard that has the greatest impulse is Skateboard C (Impulse = 25.74 Ns)
From the question,
We are to determine which skateboard has the greatest impulse. To do this, we will calculate the impulse of each skate board.
Impulse can be calculated by using the formula
I = Ft
Where I is the impulse
F is the force
and t is the time
Force = 33 N
Time = 0. 12 s
∴ Impulse = 33 × 0.12
Impulse = 3.96 Ns
Force = 33 N
Time = 0. 57 s
∴ Impulse = 33 × 0.57
Impulse = 18.81 Ns
Force = 33 N
Time = 0. 78 s
∴ Impulse = 33 × 0.78
Impulse = 25.74 Ns
Hence, the skateboard that has the greatest impulse is Skateboard C (Impulse = 25.74 Ns)

The heavier the object the faster it will fall. The lighter the object the slower to fall. You can test this for example with a rock and a piece of paper. The paper will take more time to for it to hit the ground rather than the rock which will be quicker.
