Answer:
pretty sure it's true....
Displacement only measure how far between the starting and ending point. In this case, Lisa walks around the block as a circle so the starting point is the same as the ending point. Thus, displacement is 0mile.
On the other hand, distance measures exactly how far she walks. In this case, the distance is 1 mile, same as the perimeter of the block.
Answer:
1.25C
Explanation:
When capacitance is in series we add them like this: 1/Ctotal = 1/C1 +1/C2 + 1/C3.....
1/C = 1/2 + 1/5 + 1/10 = 5 + 2 + 1/10 = 8/10
C = 10/8 = 1.25
Capacitance = Charge/potential difference(Q/V)
1.25 = Charge/12
Total charge = 1.25 ×12 =15coulombs
No. it can be zero acceleration

Answer:
Explanation:
Let the tension in horizontal rope be T₁ and in the other rope be T₂ which is making angle of 51.3⁰
The vertical component of tension T₂ will balance the weight .
= T₂ cos 51.3 = 2.9 x 9.8
T₂ = 2.9 x 9.8 / cos 51.3
= 28.42 / .625
= 45.47 N
The horizontal component of T₂ will balance T₁
T₂ sin 51.3 = T₁
45.47 sin 51.3 = T₁
T₁ = 35.48 N .
