Can someone plz help me with my project on soil? I will give brainliest.

Katena32 [7]

Answer:

Conservation Tillage preparation of soil by digging, stirring, and overturning.

Pros: reducing soil erosion, reducing the costs of soil preparation and conserving soil moisture

Cons: you will always need herbicides for weed management, planting may be delayed because of wet or cool soil temperatures. You will always have problems with weed ,insects, and plant disease.

hope that helps you

Calcula el tiempo que tarda en llegar a la Tierra la luz del sol si viaja a 300.000 km/s sabiendo que la distancia del sol a la

Strike441 [17]

Calculate the time it takes for sunlight to reach Earth if it travels at 300,000 km / s, knowing that the distance from the sun to the earth is 150,000,000 km. Express it in minutes

Answer:

8.3min

Explanation:

Given parameters:

Speed of sunlight = 300000km/s

Distance of sun and earth = 150000000km

Unknown:

Time in minutes = ?

Solution:

To solve this problem;

Speed = $\frac{distance }{time}$

Time = $\frac{distance}{speed}$

Now insert the parameters and find the speed;

Time = $\frac{150000000}{300000}$ = 500s

Now;

60s makes 1 minute

500s will give $\frac{500}{60}$ = 8.3min

Which of earth’s spheres do mountains, lakes, trees, clouds, ice, and snow represent? (which sphere does each one belong in?)?

Lapatulllka [165]

Lakes and ice are the hydrosphere. Mountains and trees are the lithosphere. Clouds are the atmosphere. Snow is debatable, but I would say it fits in the atmosphere, since it generally flows through air, and isn't ever a permanent fixture on the planet's surface (lithosphere). While it is composed from water, it doesn't exist in or around the ocean for more than extremely brief periods, so it doesn't qualify for the hydrosphere. Ice is also debatable I suppose, but I took it to mean naturally occurring ice in glaciers, which constantly freeze and unfreeze in the ocean. Ice generally doesn't describe what we would consider "land", even if it forms the top layer of ground in many arctic and antarctic environments.

A mass of 10kg is a point a on a table is moved to a point B.if the line joining A and is horizantal what is the done on the obj

IrinaK [193]

Answer:

work done on the object by gravitational force = 0 joules

Explanation:

work = force × displacement

force = mass × acceleration

so,

work = mass × acceleration × displacement

we know that mass= 10 kg , gravitational acceleration= 9.8 $m/s^2$

and displacement= 0 m since the object is not moving vertically.

so,

work = 10 × 9.8 × 0 = 0 joules

A force acts on a body of mass 13 kg initially at rest. The force

PtichkaEL [24]

Answer:

Force that acted on the body was F = 13 N

Explanation:

If once accelerated, the body covers 60 meters in 6 seconds, then its velocity is 60/6 m/s = 10 m/s

When the force was acting (for 10 seconds) the object accelerated from rest (initial velocity vi = 0) to 10 m/s (its final velocity). therefore we can use the kinematic equation for the velocity in an accelerated motion given by:

$v_f=v_i+a*t$

which in our case becomes;

$10\,m/s=0+a*(10\,s)$

and we can solve for the acceleration as:

a = 10/10 m/s^2 = 1 m/s^2

Therefore the force acting on the body, based on Newton's 2nd Law expression: F = m * a is:

F = 13 kg * 1 m/s^2 = 13 N
