Answer:

The answer is: 1000 gr., 1,000 ml, 1,000 cm3.

Explanation:

Water has a density of 1 kg / l, that is, 1 liter of water has a fair mass of 1 kilogram.

1 kilogram is equal to 1000 grams.

1 liter of water is equal to 1000 grams.

In case of volume.

1 liter is equal to 1000 milliliters.

1 liter has 1000 cubic centimeters (cc).

The answer is: 1000 gr., 1,000 ml, 1,000 cm3.

It depends of liquid's density. If it's water, only in that case 1kg of liquid has the volume of 1 liter = 1000cm3 = 1000ml and 1kg=1000g

) Force F = − + ( 8.00 N i 6.00 N j ) ( ) acts on a particle with position vector r = + (3.00 m i 4.00 m j ) ( ) . What are (a)

natali 33 [55]

To develop this problem it is necessary to apply the concepts related to the Cross Product of two vectors as well as to obtain the angle through the magnitude of the angles.

The vector product between the Force and the radius allows us to obtain the torque, in this way,

$\tau = \vec{F} \times \vec{r}$

$\tau = (8i+6j)\times(-3i+4j)$

$\tau = (8*4)(i\times j)+(6*-3)(j\times i)$

$\tau = 32k +18k$

$\tau = 50 k$

Therefore the torque on the particle about the origen is 50k

PART B) To find the angle between two vectors we apply the definition of the dot product based on the vector quantities, that is,

$cos\theta = \frac{r\cdot F}{|\vec{r}|*|\vec{F}|}$

$cos\theta = \frac{(8*-3)+(4*3)}{\sqrt{(-3)^2+4^2}*\sqrt{8^2+6^2}}$

$cos\theta = -0.24$

$\theta = cos^{-1} (-0.24)$

$\theta = 103.88\°$

Therefore the angle between the ratio and the force is 103.88°

Charge is distributed uniformly throughout the volume of an infinitely long solid Cylinder of radius R what is the electric fiel

Arada [10]

Solution :

Let us consider the Gaussian surface that is in the form of a cylinder having a radius of r and a length of A which is $\text{coaxial with the charged cylinder}$ .

The charged enclosed by the cylinder is given by,

$q=\rho V$ (here, V = $\pi r^2l$ is the volume of the cylinder)

$=\pi r^2lp$

If $\rho$ is positive, then the electric field lines moves in the radial outward direction and is normal to Gaussian surface which is distributed uniformly.
