Two electric charges, held a distance, dd, apart experience an electric force of magnitude, FF, between them. If one of the char

lorasvet [3.4K]

Answer:

$F'=2F$

Explanation:

The Coulomb's law states that the magnitude of the electrostatic force between two charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them:

$F=\frac{kq_1q_2}{d^2}$

In this case, we have $q_1'=2q_1$ :

$F'=\frac{kq'_1q_2}{d^2}\\F'=\frac{k(2q_1)q_2}{d^2}\\F'=2\frac{kq_1q_2}{d^2}\\F'=2F$

Multiply 5.036×102m by 0.078×10−1, taking into account significant figures.

Anika [276]

Answer : The significant digit is 6

Explanation :

Multiply $5.036\times10^{2}m$ by $0.078\times10^{-1}m$

Now, on multiplying

$5.036\times10^{2}m \times0.078\times10^{-1}m = 0.392808 \times10^{1}\ m^{2}$

$5.036\times10^{2}m \times0.078\times10^{-1}m = 0.0392808\ m^{2}$

Now, the significant digit is 6.

Hence, this is the required solution.

Consider the following kinds of electromagnetic waves:

marysya [2.9K]

Answer:

According to wavelengths in descending order: C, B, D, E and A

According to frequencies in descending order: A, E, D, B and C

According to speeds in vacuum: A =B =C =D =E

Explanation:

in the EM spectrum, radio waves have the longest wavelength while gamma rays have the shortest wavelength.

All EM waves travel with the same speed of $3*10^8m/s$ in a vacuum.

En un juego de béisbol, un lanzador logra

den301095 [7]

Answer:

B transferred.

Explanation:

The kinetic energy is simply transferred by transforming it into other forms of energy.

According to the law of conservation of energy "energy is neither created nor destroyed but transformed from one form to another".

The moving baseball posses kinetic energy
As it hits the bat, it is converted to mechanical and thermal energy.
The bat warms up due to the transfer of the kinetic energy.
The mechanical energy of the bat cause work to be done on it and it breaks apart.
This ensures that the energy in this process is conserved.
