1 answer:

7 0

I was hoping that there would be some options to choose from in regards to this question. Since there are no options given, so i am giving the answer based on my knowledge and hope that it helps. The charge exchanged through contact is known as static charge of electrostatic charge. This charge is exchanged mostly through rubbing between two objects.

Answer:

The speed of the automobile after 1.43s is 10 $\frac{m}{s}$

Explanation:

$a= \frac{-f}{m}= \frac{-u_{k}*m*g}{m}$

$a= -u_{k}*g=- 0.590* 9.8 \frac{m}{s^{2} }= -5.782 \frac{m}{s^{2} }$

$V_{f} = V_{i} + a*t$

$V_{f} = 18.2 \frac{m}{s} - (5.782 \frac{m}{s^{2} }* 1.43 s)$

$V_{f} = 9.93174 \frac{m}{s}$

$V_{f}$ ≅ 10 $\frac{m}{s}$

What is the frequency of microwaves of wavelength 3 cm?

tiny-mole [99]

Answer:

10 GHz

Explanation:

Applying,

v = λf.................... Equation 1

Where v = speed of microwave, λ = wavelength, f = frequency.

make f the subject of the equation

f = v/λ................ Equation 2

Note: Microwave is an electromagnetic wave, and all electromagnetic wave have the same speed, which is 3×10⁸ m/s

From the question,

Given: λ = 3 cm = 0.03 m

Constant; v = 3×10⁸ m/s

Substitute these values into equation 2

f = 3×10⁸/(0.03)

f = 10¹⁰ Hz

f = (10¹⁰/10⁹) GHz

f = 10 GHz
