The upstroke is a mechanism that helps to raise the plunger and downstroke helps to help lower the plunger. On the up-stroke of the plunger, the lower valve opens and the upper valve is closed. Whereas, on the downstroke, the lower valve closes and the upper one opens.

Answer:

3000

Explanation:

Basic kinematics (also probably one of the first formulas in your physics textbook):

Velocity=Distance÷Time

Time=2sec

Velocity=1500 m/s

Distance=??

Rearrange the variables to find the last unknown:

Distance=Velocity×Time

=1500×2

=3000 m

For the coin that is flipped straight up we have:

a. The velocity at the top of its trajectory (at the maximum height) is 0.

b. When it reaches a high point of 0.25 m above where it was released, the initial velocity is 2.21 m/s.

c. The time that the coin spends on the air is 0.44 s.

a. The velocity of the coin at the top of its trajectory is zero because in the maximum height the ball will stop and then will start to move down.

b. When the coin reaches a high point of 0.25 m above where it was released, the initial velocity can be calculated as follows:

[tex] v_{f}^{2} = v_{0}^{2} - 2gh [/tex]

Where:

[tex] v_{f}[/tex]: is the final velocity = 0 (at the maximum height)

[tex] v_{0}[/tex]: is the initial velocity =?

g: is the acceleration due to gravity = 9.81 m/s² (it is negative because its direction is the opposite to the direction of motion of the coin)

h: is the height = 0.25 m

Hence, the initial velocity of the coin is:

[tex] v_{0} = \sqrt{2gh} = \sqrt{2*9.81 m/s^{2}*0.25 m} = 2.21 m/s [/tex]

c. The time that the coin spends on the air is given by the sum of the rise time and the fall time:

Rise time

[tex] t_{s} = -\frac{v_{f} - v_{0}}{g} = -\frac{0 - 2.21 m/s}{9.81 m/s^{2}} = 0.22 s [/tex]

Since the ball is caught at the same height as it was released, the rise time is the same as the fall time, so the total time is:

[tex] t = 0.22 s*2 = 0.44 s [/tex]  

Therefore, the coin spend 0.44 seconds in the air.

Hey there, hope my answer helps :)

Answer: D) Any object that has motion has kinetic energy, while any object not in motion but with the potential to do work has potential energy.

Answer:

The sun is considered as the main source of energy since it is the source of nearly all the earth's energy. Plants produce food using sunlight, and the food we get from plants and animals also has its primary sunlight source.

Hoped it helps you.

Answer:

It is because it supplies most of our energy that we use today, directly or indirectly. It radiates light and heat or solar energy, which makes it possible to exist life on earth.

Answer: Ionic bonds usually occur between metal and nonmetal ions.

Explanation:

Hey there! Here's your answer:

10 km

Here's why:

The bus's displacement has two components, a number of km and the direction of the final position from the initial position.

The bus's displacement is the hypotenuse of the triangle, 10 km southeast of the initial position.

But southeast is only a rough estimate of the direction.

The tangent of the angle is 6/8 or .75, so the amount of angle to the east of south is 37 degrees.

South (180 degrees) minus 37 degrees is 143 degrees.

The car’s displacement is more accurately called 10 km in a direction of 143 degrees from the initial point.

Have a good day!

Explanation:

There are two forces acting upon the book. One force - the Earth's gravitational pull - exerts a downward force. The other force - the push of the table on the book (sometimes referred to as a normal force) - pushes upward on the book.

There are mainly 3 forces which acts on a book.

Listed below are the forces and their points:-

• Earth's Gravitational force of attraction- Usually, we may not consider or notice this force, but when a book falls, we understand this, because the book falls due to this gravitational force.

• Force exerted on book while pushing it- While we push a book, we apply Push Force, due to which the book moves on the pushing it on a table.

• Frictional Force- We notice that while pushing a book, it does not continuously move in motion. At a certain distance, this Frictional force increases and therefore, the book comes to a halt.

Location- Opposite of exerted force in all directions

The man on the ground in standing position has more pressure. This is because when he stands, only his legs are in contact with the ground. While lying, his body is more in contact with the ground, therefore, he exerts less pressure.

To the point, a manin standing position on the ground had more pressure.

More is the area of contact, less is the pressure efforted.

Answer:

Inertia is the tendency of an object to continue in uniform motion or remain in its state of rest. Mass is a measure of inertia,so the more huge the mass of an object is the more inertia it has.

Inertia is the tendency of an object to resist a change in its motion. Because of inertia, a resting object will remain at rest, and a moving object will keep moving. Objects with greater mass have greater inertia.

Answer:

An ionic bond is likely because they will want to give away two valence electrons in order to become stable.

Considering the octet rule and the definition of ionic bond,   the correct option is the second option: "An ionic bond is likely because they will want to give away two valence electrons in order to become stable."

Consider first the octet rule, which states that atoms combine or form ions with the goal of obtaining 8 electrons at their last level. In this way, an electronic configuration similar to that of the closest noble gas in the periodic table is reached. This happens because this configuration, of full electronic level, is very stable from the energy point of view

On the other hand, an ionic bond is a type of chemical bond that occurs when one atom gives up an electron to the other, in order for both to achieve electronic stability.

This union normally occurs between metal and nonmetal elements with different electronegativity, which means that the elements have different capacity to attract electrons. In general, metal elements are willing to donate an electron while nonmetals are willing to receive it.

In summary, an ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.

Finally,  the correct option is the second option: "An ionic bond is likely because they will want to give away two valence electrons in order to become stable."
