Answer:
8 N
Explanation:
The force between two charges is given by :

Where
k is electrostatic constant
d is the distance between two charges
It means,

When the distance is d, the force is 2 N. If the charge on each sphere is doubled, q₁' = q₂' = 2q₁ = 2q₂. New force will becomes:

So, the new force becomes 8N. Hence, the correct option is (d).
Answer:
Electric power generated= 26544kWh
Power generated by the turbine = 1105.98kw
Revenue per day = $2388.96
Explanation: Given
Air density, air=1.25kg/m3
Overall efficiency = 0.44
Diameter of turbine = 100m
Velocity= 8m/s
Unit price of electric power generated =$ 0.09
The expression for electric power generated is the product of overall efficiency and change in kinetic energy of turbine blade
n overall = W/mv^2/2
Rearranging the equation gives
W = noveral × mv2/2
W = overall × (pAv)v^2/2
W = overall × pAv^3/2
W = noverall × pAv^3/2
W = no real × pair ×pi/4 d^2×v^3/2
W = 0.44×1.25×(3.142/4 )× 100^2 × (8^3/2)
W = 1105.98kW
Electric energy power per day = E = Wt = 1105.98× 24hrs = 26544Wh
Revenue generated per day = E × Runit
= 26544 × $0.09 = $ 2388.96
The Density of this Rectangular Prism would be 7.5, since the Volume of the Rectangular Prism can be determined by using the formula: length times width times height.
5*2*4, or 2*4*5, or 5*4*2= 40, because 5*2= 10, and 10*4= 40.
The Problem hereby, states that the mass of the Rectangular Prism is 300 grams, right?
Since the Formula for calculating the Density of an Object is Mass divided by Volume, 300 divided by 40 gives you 7.5, and we wouldn't make the answer 7.5 cubed, or 7.5 squared, or 7.5 grams cubed, or 7.5 grams squared, since squared would be for finding only the Area for 2-D Shapes, and cubed would be for finding only the Volume for 3-D Shapes, but in this case that we had here, We were finding Density, which includes Mass AND Volume, not just Volume.
Answer:
The sample rate determines the maximum receive bandwidth of a direct digital conversion SDR. An analog signal must be sampled at twice the rate of the highest frequency component of the signal by an analog-to-digital converter so that the signal can be accurately reproduced.
Explanation:
Gravity
Explanation: ree fall is a special type of motion in which the only force acting upon an object is gravity. Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity.
