A monkey weighs 6.00 x 102 N and swings from vine to vine. As the monkey grabs a new vine, both vines make an angle of 35.0° wit

To solve this problem we will apply the considerations of equilibrium on a body, we will decompose the tensions into their respective components and apply the sum of forces and solving equations for the given system.

According to the graph, the sum of the horizontal components would be

$\sum T_x = 0$

$TSin35\° -TSin35\° = 0$

$0 = 0$

The sum of the vertical components is

$\sum T_y = 0$

$2TCos35\° - mg = 0$

$2TCos35\° = 600N$

$T = \frac{600N}{2Cos35\°}$

$T = 366.2N$

Therefore the net force on the new vine is 366.2N

A woman standing before a cliff claps her hands, and 2.8s later she hears the echo. How far away is the cliff? The speed of soun

ella [17]

Answer:

480.2 m

Explanation:

The following data were obtained from the question:

Speed of sound (v) = 343 m/s.

Time (t) = 2.8 s

Distance (x) of the cliff =?

The distance of the cliff from the woman can be obtained as follow:

v = 2x /t

343 = 2x /2.8

Cross multiply

2x = 343 × 2.8

2x = 960.4

Divide both side by the coefficient of x i.e 2

x = 960.4/2

x = 480.2 m

Therefore, the cliff is 480.2 m away from the woman.

Two negative charges that are both -3.0 C push each other apart with a force of 19.2 N. How far apart are the two charges ?

fgiga [73]

The Coulomb's force acting between two charges is
$F=k_e \frac{q_1 q_2}{r^2}$
where $k_e = 8.99 \cdot 10^9 N m^{-2}C^{-2}$ is the Coulomb's constant, q1 and q2 the two charges, and r the distance between them.

Using $q_1 = q_2 = -3 C$ , we can find the distance between the two charges when the force is F=19.2 N:
$r= \sqrt{k_e \frac{q_1 q_2}{F} }= \sqrt{ 8.99\cdot 10^9 \frac{(-3.0C)^2}{19.2 N} }=6.5 \cdot 10^4 m = 65 km$

"Water is absorbed in the intestine through which process"? a. simple diffusion b. active transport c. active diffusion d. facil

sdas [7]

Answer: Water is absorbed in the intestine through gradient transport. The correct option is E.

Explanation:

Absorption of water in the mammalian intestines occurs largely on the small intestine through a transport mechanism known as osmosis. Osmosis is the movement of water molecules, through a semi permeable membrane, from the region of lower solute concentration into higher solute concentration to attain an equilibrium.

For water molecules to be absorbed from the lumen into the bloodstream, it's dependent on sodium absorption. This follows the following steps:

-sodium is absorbed by co transport with glucose and amino acids.this aids to move sodium from lumen into the enterocyte.

- Rapid exportation of absorbed sodium through sodium pimps from the enterocyte.

- As sodium is pumped out of cells an osmotic gradient is formed across apical cell membrane, this helps to osmotically drive water across the epithelium. Therefore water is absorbed in the intestine through the osmotic gradient created by sodium absorption. I hope this helps. Thanks.
