Anika [276]3 years ago
7 0
Scientific knowledge is very firm in its facts and pieces of evidence that create a more precise definition. If lawmakers are able to use the scientific method in making a decision, it will make a big change and will be beneficial to the society. The set of rules will be more arranged, specific and restrictive that might change justice, tax, and law.

Explain why fluids travel faster near the center of pipes and tubes than at the edges
andreev551 [17]
I think fluids travel faster near the center of pipes and tubes better than at the edges because they are able to travel much faster, and smoother in the center rather than the edges because the fluids have to turn, which could cause the rest of the incoming fluids to stop, which would make it much slower when traveling through the edges than through the center.

A 700 g can of beans is dropped from a shelf that is 1.5 m high. What is the gravitational potential energy of this can? Round y
OLga [1]
<span>To find the gravitational potential energy of an object, we can use this equation: GPE = mgh m is the mass of the object in kg g = 9.80 m/s^2 h is the height of the object in meters GPE = mgh GPE = (0.700 kg) (9.80 m/s^2) (1.5 m) GPE = 10.3 J The gravitational potential energy of this can is 10.3 J</span>

Sphinxa [80]

Answer:

1753246.75325 V/m

Explanation:

d = Distance of separation = 1.54 cm

V = Potential difference = 27 kV

When the voltage is divided by the distance between the plates we get the electric field.

Electric field is given by

E=\dfrac{V}{d}\\\Rightarrow E=\dfrac{27\times 10^3}{1.54\times 10^{-2}}\\\Rightarrow E=1753246.75325\ V/m

The magnitude of the electric field in the region between the plates is 1753246.75325 V/m

A voltmeter and an ammeter are used to respectively monitor the voltage across and the current through a resistor connected to a
dsp73

Answer:

(a) 95 volt

(b)  134.33 volt

(c) 10.746 volt

(d) Average delivered power is 722 watt  

Explanation:

We have given value of resistance R = 12.5 ohm

Current in the ammeter i = 7.60 A

(a) Rms voltage in the resistor V=iR=7.6\times 12.5=95volt

(b) We know that rms voltage is given by v_r=\frac{v_m}{\sqrt{2}}

v_m=\sqrt{2}v_r=1.414\times 95=134.33volt

So peak voltage will be equal to 134.33 volt

(c) Maximum current is equal to i_m=\sqrt{2}i_r=1.414\times 7.6=10.746A

(d) Average power delivered in the resistor is equal to

P = VI

So P=95\times 7.6=722watt
