Explanation:

there's a formula that i definately don't remember but it exists

Answer:

Hydraulic systems work by using pressurized fluid to power an engine. These hydraulic presses put pressure on a small amount of fluid in order to generate a large amount of power. That pressure forces it against a piston on the other side of the container.

Explanation:

"Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements"

A.Bohr

His model postulated the existence of energy levels or shells of electrons. Electrons could only be found in these specific energy levels; in other words, their energy was quantised, and couldn’t take just any value. Electrons could move between these energy levels but had to do so by either absorbing or emitting energy.

Answer: 1 and 2

Explanation:

Answer: So, if the wavelength of a light wave is shorter, that means that the frequency will be higher because one cycle can pass in a shorter amount of time. ... That means that longer wavelengths have a lower frequency. Conclusion: a longer wavelength means a lower frequency, and a shorter wavelength means a higher frequency!

If the wavelength of a wave is short. It is true that the wave will have a lower frequency. A longer wavelength denotes a lower frequency.

A wave is a phenomenon that flows across a material medium without leaving any lasting mark.

Frequency is defined as the number of cycles per second. The time to make one complete cycle is the frequency and the distance between successive crests of a wave is the wavelength.

Thus, a shorter wavelength of a light wave signifies a greater frequency since one cycle may pass in a shorter amount of time. Longer wavelengths have a lower frequency.

Hence  a longer wavelength denotes a lower frequency, whereas a shorter wavelength denotes a higher frequency.

Answer:

1.Sea breeze

2. False

3.

a)Gold nugget

b)Silica sand

Explanation:

1.

The movement of air / wind blowing from the sea to the land is called sea breeze. This occurs due to high temperature differences between the water body and the land. The land is at its maximum heating, causing low pressure zones. High pressure zones in the adjacent water body causes the air to from from the sea to the land to occupy the zones of low pressures created.

2.

Air blows from areas with high pressures to those with low pressures. When an area experiences high temperatures, it causes the environment to have low pressure, creating voids , which are empty spaces that require to be filled. Additionally, the high temperatures heat the air around to cause it to rise creating the voids. Due to low pressure created, air from high pressure zones move in to occupy these zones. Hence air flows from areas with high air pressures to those with low pressures.

3.The ore for Gold is Gold nugget where as that for silicon is silica sand.

Answer:

True

Explanation:

Answer:

19 N

Explanation:

From the question given above, the following data were obtained:

Pressure (P) = 1.9 kPa

Length (L) = 10 cm

Force (F) =?

Next, we shall convert 1.9 KPa to N/m². This can be obtained as follow:

1 KPa = 1000 N/m²

Therefore,

1.9 KPa = 1.9 KPa × 1000 N/m² / 1 KPa

1.9 KPa = 1900 N/m²

Thus, 1.9 KPa is equivalent to 1900 N/m².

Next, we shall convert 10 cm to m. This can be obtained as follow:

100 cm = 1 m

Therefore,

10 cm = 10 cm × 1 m / 100 cm

10 cm = 0.1 m

Thus, 10 cm is equivalent to 0.1 m

Next, we shall determine the area of the square. This can be obtained as follow:

Length (L) = 0.1 m

Area of square (A) =?

A = L²

A = 0.1²

A = 0.01 m²

Thus, the area of the square is 0.01 m².

Finally, we shall determine the force that must be exerted on the sensor in order for it to turn red. This can be obtained as follow:

Pressure (P) = 1900 N/m²

Area (A) = 0.01 m²

Force (F) =?

P = F/A

1900 = F / 0.01

Cross multiply

F = 1900 × 0.01

F = 19 N

Therefore, a force of 19 N must be exerted on the sensor in order for it to turn red.

Velocity is defined as rate of change of displacement wit respect to time.

tangential velocity is  (11/10)πr , where r is radius of circular track.

Since, tangential velocity is,  [tex]=\frac{distance}{time}[/tex]

In one revolution, distance travelled is circumference of circular track.

If radius of circular track is r , then distance travelled in one revolution is, = 2πr  

So, 11 revolutions = 11(2πr) = 22πr

Time taken = 20 second

So, tangential velocity = 22πr/20 = (11/10)πr  meter per second.

Answer:

Under normal conditions, a magnetic material like iron doesn't behave like a magnet because the domains don't have a preferred direction of alignment. On the other hand, the domains of a magnet (or a magnetized iron) are all aligned in s specific direction.

Explanation:

Answer:

The force due to air resistance is 256 N.

Explanation:

Given;

mass of the plane, m = 5 kg

applied force on the plane, Fa = 706 N

the net force on the plane, ∑F= 450 N

Let the force due to air resistance = Fr

The net force on the plane is given as;

Net force = applied force - force due to air resistance

∑F = Fa - Fr

Fr = Fa - ∑F

Fr = 706 - 450

Fr = 256 N.

Therefore, the force due to air resistance is 256 N.

Answer:

199,430Joules

Explanation:

Gravitational potential energy is the energy possessed by a falling object due to virtue of its position.

gravitational potential energy = mass * acceleration due to gravity * height

gravitational potential energy = 55 * 9.8 * 370

gravitational potential energy = 539 * 370

gravitational potential energy = 199,430

Hence the total change in the skier's gravitational potential energy is 199,430Joules

ANSWER:
