Answer:

Rotation

Explanation:

When we talk about constant movements that Earth in space, we mainly study two, rotation and translation. In the case of the question, this refers to Rotation, which is the movement where the earth rotates about its own axis. This movement happens counterclockwise and lasts exactly 23 hours 56 minutes 4 seconds and 9 hundredths to complete, being responsible for day and night.

Why are architects and engineers concerned about surface waves

Ainat [17]

Answer:

Because they are the most destruction waves

Explanation:

Surface waves travel just below the earth’s surface. Examples of surface waves are Rayleighs and Long waves. Rayleighs cause ripples on the ground while long waves move the ground horizontally perpendicular to the direction of travel of the wave. Therefore, these waves are capable of destroying the foundations of structures and hence causing their collapse. Studying these waves allow these professionals to design foundations strong enough to withstand these waves.

A sodium-potassium pump _____. moves three potassium ions out of a cell and two sodium ions into a cell while producing an atp f

SVETLANKA909090 [29]

Move three sodium ions out of a cell and two potassium ions into a cell while consuming an atp for each cycle

Explanation:

By pumping three (3) Na+ to the outside and two (2) K+ to the inside of the cell, there is a net positive charge on the outside leaving the inside of the cell electronegative. This process is achieved by the Na+/K+ pump and is a process that consumes ATP energy.

This is much more important in a neuron cell who ¾ of its energy is used to maintain a -70mV resting potential that is important for the nerve to pass impulse when depolarised.

In other cells, the gradient created in important in maintaining the homeostatic osmolarity inside the cell to avoid swelling and lysis of cells due to uptake of excess water by osmosis. The Na+ gradient is also used to import other molecules into the cell such as glucose and amino acids. These molecules are coupled with Na+ and then are absorbed efficiently as the Na+ flow back inside the cell down the Na+ concentration gradient.

1. Which force is being applied by a vendor when he is pushing the pushcart? *

marta [7]

Answer:

1. Muscular force

2. Speed decreases

3. higher than

4. decreases

5. air pressure

6. Inversely proportional to the area of contact

7. 20 N

8. 400 N / m2

9. 150 N

10. friction

Explanation:

1. During pushing the pushcart the person is required to use strength of his arms and legs muscles that will creat a force between the surfaces, hence the force used is muscular force.

2. The speed of car decreases while applying brakes because a friction is generated between the brakes and the wheel that reduces the kinetic energy of vehicle and decreases the speed of the vehicle.

3. The pressure of the water at the bottom of the pond is higher than at the surface of pond because water pressure increases with the depth of the water. Water pressure increases in the depth because weight of water over the body icreases as going deep.

4. At higher altitude the atomspheric pressure decreases because as the height in atmosphere increases the amount of air molecules decreases and so, less oxygen for breathing.

5. Air pressure allows the dropper to fill inks as dropper exerts a force on a surface of ink and due to the low pressure inside the dropper sucks up the liquid.

6. Pressure is defined as the perpendicular force exerted at the surface or it means force per unit area. Pressure is directly proportional to the force and inversely proportional to area of contact.

7. The boys exerts pressure in opposite direction on an object, hence the resultant force will be

resultant force = force 1 - force 2 = 60N−40N=20N.

8. pressure (P) is equal to force (F) per unit area (A)

P = F / A

= 800 / 2

= 400 N / m2

9. Pressure (P) = 300 Pa

Area of Cross-section (A) = 0.5 m²

Force = P × A

= 300 × 0.5

= 150 N

10. Friction is the force that is always applied against or opposite to the moving direction of an object. Friction is responsible to stop the movement of any moving object such as vehicles and sliding objects.

Hence, the correct option of the questions are:

1. Muscular force

2. Speed decreases

3. higher than

4. decreases

5. air pressure

6. Inversely proportional to the area of contact

7. 20 N

8. 400 N / m2

9. 150 N

10. friction

In general the surface of a tree has a harder feel than does the surface of a dog. What cell characteristic of each organism can

Alik [6]

This is because plants has cell wall while dog doesnt have. A cell wall is a structural layer surrounding some types of cells, situated outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.
