Answer:

The correct answers are: Bacteria, Horses, Humans and Mushrooms.

Explanation:

All living organisms are made up of cells. A cell is a microscopic atomic unit and is made up of cytoplasm, one or more nuclei, and a membrane.

They are divided into eukaryotic cells (with nucleus) and prokaryotic cells (they do not have a nucleus).

Depending on the number of cells that living organisms have, they can be classified as single-celled organisms, which are made up of one cell. For example bacteria.

Or they can be multicellular organisms, formed by two or more cells, for example horses.

In a laboratory experiment, an ultrasound detector located at D is used to measure the distances of two moving objects, P and Q.
Tatiana [17]
D^2 = p^2 + q^2  - 2 pq cos D

d^2 = (4.24)^2 + (4.24)^2  - 2. (4.24) (4.24) cos 68

d^2 = 2 (4.24)^2 -  2. (4.24) (4.24) cos 68

d = 4.74

so the answer will be letter. C

A 96.0 kg hoop rolls along a horizontal floor so that its center of mass has a speed of 0.240 m/s. How much work must be done on
Ede4ka [16]

Answer:

The work done by the hoop is equal to 5.529 Joules.

Explanation:

Given that,

Mass of the hoop, m = 96 kg

The speed of the center of mass, v = 0.24 m/s

To find,

The work done by the hoop.

Solution,

The initial energy of the hoop is given by the sum of linear kinetic energy and the rotational kinetic energy. So,

K_i=\dfrac{1}{2}mv^2+\dfrac{1}{2}I\omega^2

I is the moment of inertia, I=mr^2

Since, \omega=\dfrac{v}{r}

K_i=mv^2

K_i=96\times (0.24)^2=5.529\ J

Finally it stops, so the final energy of the hoop will be, K_f=0

The work done by the hoop is equal to the change in kinetic energy as :

W=K_f-K_i

W = -5.529 Joules

So, the work done by the hoop is equal to 5.529 Joules. Therefore, this is the required solution.

It takes 8 seconds for a pulley system to lift a load that weights 400N to a height of 10 m. How much power is required?.
mariarad [96]

Answer:

C. 500 watts

Explanation:

power is defined as the rate of work done

power=\frac{work.done}{time}

When a force causes a object to move, work is being done on the object by the force.

work.done=force*displacement\\=400*10\\=4000J

power=\frac{4000J}{8s}\\=500 W

Determine Force. 589J of work was accomplished over a distance of 1100m, how much force was exerted? Include the correct units.
LiRa [457]

Answer:

Explanation:

Given:

A = 589 J

D = 1 100 m

____________

F - ?

A = F·D

F = A / D = 589 / 1100 ≈ 0.54 N
