The length of lines 1, 2, and 3 is the same. Each line has the same number of dots, so your finger moved along each line in the

same amount of time. One measurement of motion is average speed:
average speed = total distance ÷ total time

Would the average speed of your finger be the same or different for the three lines?

Man well speed is equal to distance over time so yea that’s the formula

Answer:

The times would be the same for all the lines.

Explanation:

The question says that 1,2, and 3 are all the same length, have the same number of dots, and you moved your finger in the same amount for each line. Since the total distance and the total time are the same, the average speed will also be the same.

A copper wire (density equal to 8900 kg / m3) 0.3 mm in diameter "floats" due to the force of the earth's magnetic field, which
Andrews [41]

Answer:I=112.094\ A

Explanation:

Given

density \rho =8900\ kg/m^3

diameter d=0.3\ mm

Magnetic field B=5.5\times 10^{-5}\ T

Force on the current carrying conductor placed in a magnetic field

F=BIL\sin \theta

where L=length of conductor

\theta=angle between magnetic field and current

If the wire is floating then weight must be balanced by weight of wire

Weight=mg=\rho ALg

Therefore

\rho ALg=BIL\times \sin 90

8900\times \frac{\pi}{4}(0.3\times 10^{-3})^2L\times 9.8=5.5\times 10^{-5}\times I\times L

I=\frac{8900\times \pi\times 9\times 10^{-8}\times 9.8}{4\times 5.5\times 10^{-5}}

I=112.094\ A

A person sitting still in a moving airplane is considered to be... (SP1a) a. Motionless in relation to everything in the plane.
vichka [17]

Answer:

C. Both a and b

Explanation:

Firstly, persons and objects in a moving plane as described in this question, are moving at the same speed as the plane even if there is no individual movement of these objects.

However, this question describes a person sitting still in a moving plane. This means that;

- The person is motionless in relation to everything in the plane i.e the person is not moving even if other things in the plane are.

- The person is in motion compared to everything on the ground i.e. the person is moving at the same speed as the plane, hence, in comparison with the ground, the person is moving.

Therefore, options A and B are correct

Two resistors, A and B, are connected in a series circuit with a battery. The resistance of A is twice that of B. Which resistor
IgorC [24]

Answer:

A dissipates more power.

Explanation:

  • In a series circuit, the current is the same at any point in it.
  • The power dissipated in any resistor follows Joule's law, as follows:

        P = I^{2} * R

  • So, for a given current, the power is directly proportional to the resistance of the resistor.
  • In this case, as resistor A has twice the resistance of resistor B, A dissipates twice more power than B.
