Which biogeochemical cycle is relied upon for plant photosynthesis? 1)Phosphorus 2)Nitrogen 3)Carbon 4)Hydrologic

Answers

Answer 1

Answer: I think the correct answer would be carbon. It is the Carbon cycle that is relied upon for plant photosynthesis. One of the important substance needed for photosynthesis to occur is carbon dioxide so it should be involved in the carbon cycle.

Answer 2

Answer:

carbon because we breath out carbon and plants eat it bascially

An oil tanker, initially traveling west at 18 km/h is accelerated uniformly until it is traveling east at 21.6 km/h. The acceleration is 0.20 m/s2 towards the east. Compute the total displacement from the tanker’s initial position.Answer in meters.

Answers

Answer:

27.5 m

Explanation:

Given:

u = 18 km/h = 5 m/s

v = 21.6 km/h = 6 m/s

a = 0.20 m/s²

Find: s

v² = u² + 2as

(6 m/s)² = (5 m/s)² + 2 (0.20 m/s²) s

s = 27.5 m

Coal _____. is a renewable resource can easily be replenished is formed from plant remains is the least-polluting energy source

Answers

Coal . . . . .

-- is a renewable resource that can easily be replenished.
It happens by itself, and you don't even need to do anything,
but it takes several million years.

-- Is formed from plant remains, and

-- is perhaps the MOST polluting energy source.

There is only supposed to be one answer choice, so the correct answer is is formed from plant remains.

Suppose that we repeat the experiment shown in the video, but we replace one of the cylinders with a cylinder that has twice the radius (and use larger containers of water). If the height of the original cylinder is \rm h, how deeply must we submerge the new cylinder to get the same weight reduction as in the video?

When unbalanced forces act on an object, __________________. the object accelerates friction becomes greater than the net force the objects speeds up the net force is zero?

Answers

When an unbalanced force acts on an object, the object accelerates. We can immediately rule out B and D, as friction changes based on the material and by applying a force the net force can’t be zero. It can be easy to say that the object will speed up after the force is applied (and it often does!), but take a braking car, for example. An external force of friction is applied to the brakes, causing an acceleration but in such a fashion that the car slows down. So, although an object can speed up after a force is applied, it isn’t always guaranteed.

A 5.0-kg object is pulled along a horizontal surface at a constant speed by a 15-n force acting 20° above the horizontal. How much work is done by this force as the object moves 6.0 m?

Answers

A 5.0 kg object is pulled by a 15-N force acting 20 °C above the horizontal. After moving for 6.0 m, the work done is 85 J.

What is work?

In physics, work is the energy transferred to or from an object via the application of force along a displacement.

A 5.0 kg object is pulled by a 15-N force acting 20 ° above the horizontal. We can calculate the work done after the object moved 6.0 m using the following expression.

W = F × s × cosθ

W = 15 N × 6.0 m × cos 20° = 85 J

where,
