Answer: C. 8.0 m west
Explanation: The arrows are going 15 m west and 7.0 m east. 7 meters of the west will cancel out because 15-7=8. Subtract the smaller number from the bigger number, which is west minus east. The answer will be 8.0 m west.
Answer:
The velocity is 6 m/s
Explanation:
We use the formula of kinetic energy=
Ec= 1/2 x m x v2
2160 J = 1/2 x 120 kg x v2
v =![\sqrt[n]{x} 2160Joulex2/120kg\\](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%7D%202160Joulex2%2F120kg%5C%5C)
v= 6m/s
1Joule= 1 kgm2/s2
Answer:
Explanation:
That Universe Consists of Matter
Explanation:
Since the comb has a net charge, it attracts the paper, which has a net charge equal to zero. When the paper touches the comb, an electrical interaction is established between the charge of the comb and the neutral paper, because of this, the paper now has a net charge with the same sign of the comb and they repel.
