How can gecko catch mosquitoes?

How can gecko catch mosquitoes?

Its fingers and toes are expanded, and skin folds are formed under it, with dense glandular hair. It has adhesion ability. In other words, it can fly on the eaves and walk on the wall, and it can go wherever the mosquito can stay. Its skin has protective color, which can not be easily detected. Due to the special distribution of muscles, its tongue can quickly attack, stick to the mosquito, and then recover, Lizards like chameleons are very powerful at catching insects

Xiao Ming uses an energy meter to measure the electric power of his household appliances. When only one of the appliances in the circuit works, the measured energy consumption within 15 minutes is 0
How to calculate?

The electric energy meter measures and displays the electric energy consumed by the electric appliance over a period of time
1. The power of the electric appliance is very small, and the accumulated energy consumed within 15 minutes cannot be displayed on the electric energy meter
2. The watt hour meter is large in size and low in sensitivity. It is indifferent to the consumption of small power electrical appliances
3. The electric energy meter is broken

Factorization 9A ^ 2-4b ^ 2
9a^2-4b^2; a^2-(1/25)b^2; x^2-4y; -a^4+16

9a^2-4b^2=(3A+2B)(3A-2B)
a^2-(1/25)b^2=(A+B/5)(A-B/5)
X ^ 2-4y = (x + 2Y) (x-2y)
-A ^ 4 + 16 = (4 + a) (4-A) = (4 + a) (2 + a) (2-A)

What is 0.1k ohm

100 euro

If 1 / 2 * 3 = 1 / 2 * 3 / 2 * 4 / 3, 1 / 7 * 4 = 1 / 7 * 8 / 2 * 9 / 3 * 10 / 4, then 1 / 2 * 4 + 1 / 3
※3=

1/2※3=1/2*2/3*3/4
1/2※4+1/3
=1/2*2/3*3/4×4/5+1/3
=1/5+1/3
=8/15

Can resistor and bulb in parallel control bulb brightness

Yes, in the case of constant power supply, reduce the resistance of the resistor

A 3V voltmeter connected in series with an 8K ohm resistor changes its range to 15. A 3V voltmeter connected in series with an 8K ohm resistor changes its range to 15

Because the voltmeter is connected in series with the 8K ohm resistor, their voltage ratio is the resistance ratio (because the original range of the voltmeter is 3V, later it became 15V, so the voltage of 12V is shared when the 8K ohm resistor is connected in series with the voltmeter), so the resistance ratio of the voltmeter to the 8K ohm resistor = voltage ratio = 3V: 12V = 1:4
Therefore, the internal resistance of the voltmeter is 2 kiloohm
I wonder if there is something wrong with your topic

When k is a value, the solution of 4 / 3 + 8x equals 7K + 6x, which is 6 times larger than the solution of the equation K (2 + x) = x (K + 2) about X
To find the value of K, we need to complete the steps,

The first equation is reduced to 4 / 3 + 2x = 7K. The second equation is multiplied by 2K + KX = KX + 2x to get k = X
Because the solution of the second equation is 6 smaller than that of the first equation, the solution of the first equation x = K + 6 is substituted by 4 / 3 + 2 (K + 6) = 7K, so k = 56 / 15

What is the change of resistance when a resistance wire with uniform thickness is cut into two equal lengths
If two resistance wires are connected in parallel, what's the change

Let's simply say No:
After a resistance wire with uniform thickness is cut into two equal length sections, the resistance value of each section is half of the original one;
If the two resistance wires are connected in parallel, the total resistance is one fourth of the original
For example, it turns out to be 4 pairs, and after cutting it into two equal length segments, each segment is 2 pairs,
The total resistance is 1 couple when the two resistance wires are connected in parallel
Because you don't want formula, I won't say formula
