Answer: b. deposition

Explanation:

Erosion is a phenomenon in which there is movement of rocks, sediment, or soil as a result of human activities or by the force of moving wind.

Deposition is a phenomenon when the movement of the transported materials slow down and are dropped in a new location.

Weathering is a phenomenon in which the rocks are broken by physical or chemical factors.

Compaction is a phenomenon in which there is formation of a solid specimen of defined geometry due to association of particles generally caused by compression.

The maximum force that a grocery bag can withstand without ripping is 250 n. Suppose that the bag is filled with 20 kg of grocer

zhannawk [14.2K]

Answer:

Groceries stay in the bag.

Explanation:

Given:

Maximum force = 250 N

Bag filled with = 20 kg

Lifted acceleration = $5.0\ m/s^2$

Solution:

We need to calculate the exerted force on the grocery bag by using Newton's second law.

$F = ma$

Where:

F = Exerted force on the object.

m = Mass of the object in kg

a = Acceleration of the object in $m/s^2$

Now, we substitute m = 20 kg and a = $5.0\ m/s^2$ in Newton's second law,

$F = 20\times 5.0$

$F = 100\ m/s^2$

Since, the exerted force on the bag is less than 250 N, the groceries will stay in the bag.

You want to place a mirror at a blind turn on the staircase in your house. Which would be best suited for this purpose?

Eduardwww [97]

You can't see beyond a blind turn, so a mirror would allow you to see around the corner.

Can somebody please explain how a compass can be used to find North?

Ira Lisetskai [31]

if the pointy thingy in your compass is pointing north, that means it's being (pulled toward) something near Earth's north pole

A boy standing on the bridge kicks a stone into the water below. He kicks the stone with a horizontal velocity of 8.06 m/s. It l

Ronch [10]

Time taken to reach water :

$t = \dfrac{D}{v}\\\\t=\dfrac{6.78}{8.06}\ s\\\\t=0.84\ s$

Now, initial vertical speed , u = 0 m/s.

By equation of motion :

$h = ut +\dfrac{at^2}{2}$

Here, a = g = acceleration due to gravity = 9.8 m/s².

So,

$h = 0(t) +\dfrac{9.8\times 0.84^2}{2}\\\\h=3.46\ m$

Therefore, the height of the bridge is 3.46 m.

Hence, this is the required solution.
