Answer: B
Explanation:
The equation to find momentum is velocity*mass. Without velocity, there would be no momentum. Therefore the object CAN NOT be at rest.
Answer:
fem = -0.126 V
Explanation:
Faraday's law is
fem =
where the flow is
Ф = B . A = B A cos θ
bold letters indicate vectors.
In this case, the normal to the area is parallel to the magnetic field, so the angle is zero and the cos0 = 1
fem =
in this case they indicate that to carry the loop from outside to inside the field in Δt = 5 s, so we can change them by variations
fem =
let's calculate
fem = - 0.7 (0.9 -0) / 5
fem = -0.126 V
If a red blood cell is 7 x m in size, it means that such a cell is 7 microns or micrometer in size. The unit that completes the sentence will, thus, be microns or micrometer.
According to international system of measurement:
- m = decimeter
- m = centimeter
- m = millimeter
- m = micrometer or micron
- m = nanometer
Thus, a measurement of 7 x m is the same is 7 micons or 7 micrometer.
