Answer:
C
Explanation:
V-V₀=at
a=(V-V₀)/t
a=(10-20)/5=-2 m/s²
Acceleration of the car is -2 m/s²
Answer:
Since the waves must carry a great deal of visual as well as audio information, each channel requires a larger range of frequencies than simple radio transmission. TV channels utilize frequencies in the range of 54 to 88 MHz and 174 to 222 MHz. (The entire FM radio band lies between channels 88 MHz and 174 MHz.)
Answer:
14.7 Volt
Explanation:
C1 = 2.74 F, C2 = 7.46 F, C3 = 10.1 F
Here C1 and C3 are in parallel
So, Cp = C1 + C3 = 2.74 + 10.1 = 12.84 F
Now Cp and C2 are in series
1 / C = 1 / Cp + 1 / C2
1 / C = 1 / 12.84 + 1 / 7.46
C = 4.72 F
Let q be the total charge
q = C V = 4.72 x 40 = 188.8 C
Voltage across C2
V2 = q / C2 = 188.8 / 7.46 = 25.3 V
Voltage across C2 or c3
V' = V - V2 = 40 - 25.3
V' = 14.69
V' = 14.7 Volt
Explanation:
Eq 2 ) is Equation for force on a charge Q1 due to charge Q2 separated by a distance R .. it is Equation for Coloumb's law !!
Where , k = 1/4π€
Eq 3 ) is Equation for force on mass m1 due to mass m2 separated by distance R .. it is Newton's law of Gravitation
Where , G = universal Gravitation constant

Longer term forecasts not only use different methodologies, such as qualitative vs. quantitative, they also tend to consider different issues.</span>
