Answer:

The total momentum of the carts is p = 5000 g cm/s                        

Explanation:

Given data,

The mass of the cart 1, m₁ = 500 g

The mass of the cart 2, m₂ = 250 g      

Let the velocity of the cart 1 be, v₁ = 5 cm/s

The velocity of the cart 2 be, v₂ = 10 cm/s

According to the law of conservation of momentum, then the total momentum of the carts before and after will be the same.

Therefore,

                           p = m₁v₁ + m₂v₂

                               =  500 x 5 + 250 x 10

                                = 5000 g cm/s

Hence, the total momentum of the carts is p = 5000 g cm/s

What is the electric force acting between two charges of -0.0050 C and 0.0050 C that are 0.025 m apart?
nika2105 [10]

Answer:

(A) -3.6\times 10^8\ N

Explanation:

Given:

Charge of one particle (q₁) = -0.0050 C

Charge of another particle (q₂) = 0.0050 C

Separation between them (d) = 0.025 m

We know that, from Coulomb's law, electric force acting between two charged particles is given as:

F_e=\dfrac{kq_1q_2}{d^2}\\\\Where,k\to Coulomb's\ constant = 9\times 10^9\ N\cdot m^2/C^2

Plug in the given values and solve for electric force, F_e. This gives,

F_e=\frac{(9\times 10^9\ N\cdot m^2/C^2) (-0.0050\ C)(0.0050\ C)}{(0.025\ m)^2}\\\\F_e=\frac{-2.25\times 10^{-4}\times 10^9}{6.25\times 10^{-4}}\ N\\\\F_e=-3.6\times 10^8\ N

Therefore, option (A) is correct. Negative sign implies that the nature of electric force is attraction.

A tissue box has regular dimensions
vova2212 [387]

Considering the volume of a rectangle, the volume of the tissue box is 3,239.1 cm³.

<h3>What is volume</h3>

Volume is a scalar-type metric quantity that is defined as the extension in three dimensions of a region of space. In other words, the volume corresponds to the space that the shape occupies.

<h3>Volume of a rectangle</h3>

To calculate the volume of a rectangle, it is necessary to multiply its 3 dimensions: length ×width×height. Volume is expressed in cubic units.

<h3>Volume of the tissue box</h3>

In this case, you know:

  • Length: 11.8 cm
  • Width: 12.2 cm
  • Height: 22.5 cm

Replacing in the definition of volume of a rectangle:

Volume of the tissue box= length ×width×height

Volume of the tissue box= 11.8 cm× 12.2 cm× 22.5 cm

Solving:

<u><em>Volume of the tissue box= 3,239.1 cm³</em></u>

Finally, the volume of the tissue box is 3,239.1 cm³.

If you take rocks from the Earth to the moon (5 points)
Lemur [1.5K]
