Answer:
A- series B- parallel
Explanation:
In order to measure current in a circuit, the multi-meter needs to be placed in series with the circuit while when measuring voltage, the multi-meter needs to be placed in parallel with the circuit.
It should be however noted that the same current flows in a series connected circuit and same voltage flows through loads connected in parallel. The ammeter is placed in series with the load to ensure that same value of currents is flowing in both the ammeter and loads(since same current flows in series connected circuit elements and all the amount of voltage must be made to appear on the load for the current to be measured accurately.
Voltmeter is connected in parallel to the load due to high value of current possessed by the voltmeter. The parallel connection will cause the current flowing through the voltmeter to reduce to zero so that it won't have effect (increase) on the amount of current initially on the resistor thereby measuring the exact amount of voltage on the load.
Answer: the weight would be 4.6 (I think i don’t know))
Explanation:
Like windmills they use the winds to generate their power.
Answer:
The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.
Answer:
x = 0.081 m.
Explanation:
a) To find how much does the atmospheric pressure cause the spring to compress we need to use the following equation:
(1)
<u>Where</u>:
F: is the force
k: is the spring constant = 3300 N/m
x: is the distance of compression =?
The force can be found as follows:
<u>Where</u>:
P: is the atmospheric pressure = 101325 Pa
A: is the area of the piston = πr²
r: is the radius = 0.029 m
Now, from equation (1) we can find x:
Therefore, the atmospheric pressure causes the spring to compress 0.081 m.
I hope it helps you!
