Answer:

  (b)  0.29 m/s

Explanation:

The average speed is found by dividing the net displacement by the amount of time it took to achieve that displacement.

__

The net displacement is ...

  6 m -8 m = -2 m . . . . . where north is positive

The total time is ...

  2 s + 5 s = 7 s

Then the distance per unit time (speed) is ...

  (2 m)/(7 s) = 2/7 m/s ≈ 0.29 m/s

Answer:

Option D

Explanation:

Resistors are said to be connected in “Series”, when they are daisy chained together in a single line. Since all the current flowing through the first resistor has no other way to go it must also pass through the second resistor and the third and so on. Then, resistors in series have a Common Current flowing through them as the current that flows through one resistor must also flow through the others as it can only take one path.

Total Resistance = R₁ + R₂ +R₃ +R₄ ohm

Note then that the total or equivalent resistance, R has the same effect on the circuit as the original combination of resistors as it is the algebraic sum of the individual resistances.

Total resistance R = 3 + 3 + 3 +3

                             = 12 ohm

A 200 g air-track glider is attached to a spring. The glider is pushed 10.0 cm against the spring, then released. A student with
fiasKO [112]

Answer:

5.5N/m

Explanation:

Calculation for What is the spring constant

First step is to calculate the time period

T = 12 second/10

T = 1.2 second

Now let calculate the spring constant using this formula

k=4π²m/T²

Where,

m=0.2kg

T=1.2second

k represent spring constant=?

Let plug in the formula

k=4π²×0.2kg/(1.2)²

k=39.48×0.2kg/1.44

k=7.90/1.44

k=5.48N/m

k=5.5N/m ( Approximately)

Therefore the spring constant will be 5.5N/m

Zigmanuir [339]

Answer:

Animals are treated as humanely as possible.

Explanation:

Ethical guidelines relating to animals are laid down principles or laws that guide against the maltreatment of animal in any way during or for a research. As the use of some animals for various researches can not be over emphasized, because of the close proximity between their body tissues to that of humans.

The ethical guidelines enforce treating animals as humanly as possible or achievable. This ensure appropriate handling and treatment of the animals.
