Answer:
1 Ohm
Explanation:
Resistance: Voltage/Current
R: 1.5/ 1.5 = 1 Ohm
Answer:
Animal Cells
Explanation:
they dont have cell walls because they dont need them. Wall cells are found in plants, which animals dont need.
Are there supposed to be multiple choices for this question?
1) Magnetic field
2) Electric current
3) Force
Answer:
<em>the minimum speed that the ball must have so that the cord does not become slack is</em> <em>2.02 m/s.</em>
<em></em>
Explanation:
In order to avoid slack, the centripetal force of the ball must equal its weight at the top of the circle. Therefore,
F_c = F_g
m v² / r = m g
v² = g r
v = √[g r]
v = √[(9.8 m/s²)(0.417 m)]
<em>v = 2.02 m/s </em>
Therefore,<em> the minimum speed that the ball must have so that the cord does not become slack is</em> <em>2.02 m/s.</em>
