Express 68 rations in dekarations

rewona [7]

You have to take note of the prefix because it gives you a hint of its value with respect to the base value. The base value is ratio. When the prefix is deka, that means that 1 ration is equal to 0.1 dekaration according to the metric system. The conversion is as follows:

68 rations * 0.1 dekarations/1 ration = 6.8 dekarations

two-point charges are 10.0 cm apart and have charges of 2.0 uc and -2.0uc respectively What is the magnitude of the electrical f

Scorpion4ik [409]

Answer:

Electric field due to two charges is given as

$E = 1.44 \times 10^7 N/C$

Explanation:

As we know that two charges are opposite in nature

So the electric field at the mid point of two charges will add together

so the net field is given as

$E = 2\frac{kq}{r^2}$

now we have

$q = 2\times 10^{-6} C$

$r = 5 cm = 0.05 m$

now we have

$E = 2\frac{(9\times 10^9)(2\times 10^{-6})}{0.05^2}$

$E = 1.44 \times 10^7 N/C$

an oscilloscope has a time/div setting of 50ms and there are 10 divisions on the time scale. a sine wave on the oscilloscope dis

mamaluj [8]

Answer:

The frequency is f = 6Hz

Explanation:

Given

The time division setting is $d_t =50ms = 50*10^{-3}s$

The number of division is $n= 10$

The total time for 10 division can be mathematically obtained as

$T_{total} = 10 *50*10^{-3}$

$=500 *10^{-3}s$

From the question the time for 3 cycle is

$T_{total} = 500*10^{-3}s$

Then the for one cycle which equivalent to the Period $(T)$ $= \frac{T_{total}}{3}$

$= \frac{500 *10^{-3}}{3}$

The frequency is generally given as $f = \frac{1}{period} = \frac{1}{T}$

Now substituting values we have

$f = \frac{3}{500 *10^{-3}}$

$= 6Hz$
