Answer:

Explanation:

A car of mass 1000kg pushes 2000kg

The forward force is 4500N

Then, summation of the forward forces is ma

ΣF = Σ(ma) = m1a1 + m2a2

Since the body are moving together then, they will have the same acceleration(a)

ΣF = Σ(ma) = (m1+m2)a

Let m1=1000kg.

m2=2000kg

F=4500N

Then,

4500=(1000+2000)a

4500=3000a

Then,

a=4500/3000

a=1.5m/s²

A certain radio wave has a frequency of 2.0 x 10^6 Hz. What is its wavelength?
evablogger [386]

<span>1.    </span>Electromagnetic radiation are represented in waves. Each type of wave has a certain shape and length. The distance between two peaks in a wave is called the wavelength. This value is equal to the speed of light divided by the frequency.

Wavelength = c/f
Wavelength = 3x10^8 / </span><span>2.0 x 10^6</span>

Wavelength = 150 m

50°C is equivalent to a 82 F b- 90"F c 122"F
andre [41]

Answer:

50°C = 122 Fahrenheit

Explanation:

Here, we need to convert 50°C to F i.e. Fahrenheit. The conversion formula from degree Celsius to Fahrenheit is as follows :

^{\circ}F=(^{\circ}C\times \dfrac{9}{5})+32

Where, ^{\circ}C=50^{\circ}C

^{\circ}F=(50\times \dfrac{9}{5})+32

^{\circ}F=122^{\circ} F

So, 50 degree Celsius is equal to 122 degree Fahrenheit. Hence, this is the required solution.

A huge (essentially infinite) horizontal nonconducting sheet 10.0 cm thick has charge uniformly spread over both faces. The uppe
TiliK225 [7]

Answer:

E = 6.77 *10^{3} N/C

Explanation:

THE GIVEN sheet can be taken as two horizontal force  with surface charge density is

at one surface is ∈_1 = 95*10^ {-9} C/mm2

at oher surface is ∈_2= -25*10^{-9} C/mm2

the magnitude of electric field due to surface charge is given as\frac{∈}{2∈_O}

So, electric field at P (2 CM below from surface is) = E_1 +E_2

E = \frac{∈_1}{2∈_O} +\frac{∈_2}{2∈_O}

E = \frac{95*10^{-9} +25*10^{-9}}{2*8.85*10^{-12}}

E = 6.77 *10^{3} N/C
