A 4.4 nC charge exerts a repulsive force of 36 mN on a second charge which is located

zhenek [66]

The magnitude and sign of the second charge will be + 8.6241×10⁻¹⁹ C. The principal of the Columb's law is used in the given problem.

<h3>What is Columb's law?</h3>

The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Charges that are similar repel each other, whereas charges that are diametrically opposed attract each other.

They will repel, moving in opposite directions at the same speed. Because the magnitude and nature of the charge are the same.

The given data in the problem is;

q₁ is the charge 1 = 4.4 nC = 4.4 ×10⁻⁹ C

F is the repulsive force = 36 mN =36 ×10⁶ N

d is the distance = 0.70 m

The Coulomb force is found as;

$\rm F = \frac{Kq_1q_2}{r^2}\\\\\ \rm 36\times 10^6 = \frac{9 \times 10^9 }{(0.7)^2} \times 4.4 \times 10^{-9} \times q_2\\\\\ q_2 = 8.6241 \times 10^{-19 } \ C$

Hence, the magnitude and sign of the second charge will be + 8.6241×10⁻¹⁹ C.

Determine the apple's kinetic energy, KE, the gravitational potential energy of the system, gravity, and the total mechanical en

guajiro [1.7K]

Answer:

7.45

Explanation:

At 3.0 m PE = m*g*3.0, KE = m*g*(4.0 - 3.0)

At 2.0 m PE = m*g*2.0, KE = m*g*(4.0 - 2.0)

At 3.0 m PE = m*g*1.0, KE = m*g*(4.0 - 1.0)

At 0 m PE = 0, KE = m*g*h = total energy = 7.45 J

Suppose you are asked to find 91,321,972×0.007004. Doing a quick estimate by rounding the numbers in scientific notation, what v

slamgirl [31]

Answer:

Product, $P=9.1321972\times 10^7\times 7.004\times 10^{-3}$

P = 639619.091888

Explanation:

In this case, we need to find the product of two numbers. These are as follows :

$N_1=91321972=9.13\times 10^7$

$N_2=0.007004=7.004\times 10^{-3}$

On doing calculation, we get the product of two numbers as :

$P=N_1\times N_2$

$P=9.1321972\times 10^7\times 7.004\times 10^{-3}$

P = 639619.091888

In scientific notation the product of two number is given by :

$P=63\times 10^4$

Hence, this is the required solution.

A fisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surfac

azamat

Answer:

a. Speed = 1.6 m/s

b. Amplitude = 0.3 m

c. Speed = 1.6 m/s

Amplitude = 0.15 m

Explanation:

a.

The frequency of the wave must be equal to the reciprocal of the time taken by the boat to move from the highest point to the highest point again. This time will be twice the value of the time taken to travel from the highest point to the lowest point:

frequency = $\frac{1}{2(2\ s)}$ = 0.25 Hz

The wavelength of the wave is the distance between consecutive crests of wave. Therefore,

Wavelength = 6.4 m

Now, the speed of the wave is given as:

Speed = (Frequency)(Wavelength)

Speed = (0.25 Hz)(6.4 m)

Speed = 1.6 m/s

b.

Amplitude is the distance between the mean position of the wave and the extreme position. Hence, it will be half the distance between the highest and lowest point:

Amplitude = (0.5)(0.6 m)

Amplitude = 0.3 m

c.

frequency = $\frac{1}{2(2\ s)}$ = 0.25 Hz

Speed = (Frequency)(Wavelength)

Speed = (0.25 Hz)(6.4 m)

Speed = 1.6 m/s

Amplitude = (0.5)(0.3 m)

Amplitude = 0.15 m
