I searched it up:

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"

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.

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

Answer:

v₀ = 3.77 [m/s]

Explanation:

This problem can be solved in a simple way by means of the following equation of kinematics.

[tex]y=y_{o}+v_{o}*t+\frac{1}{2}*g*t^{2}[/tex]

where:

y - yo = 0.441 [m]

Vo = initial velocity [m/s]

g = gravity acceleration = 9.81 [m/s²]

t = time = 0.625 [s]

[tex]0.441 = v_{o}*(0.625)-\frac{1}{2} *9.81*(0.625)^{2} \\2.357 = v_{o}*0.625\\v_{o}=3.77[m/s][/tex]

Note: The sign of the acceleration is negative since the movement of the basketball player is against of the gravity acceleration.

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:

The formula for weight goes- Weight=Mass*Gravity

We need to re arrange the formula in order to find the mass

so, mass=w/g

~If the person is on Earth then we can substitue the official the value of gravity as 9.8m/s^2 (this value is fixed)

~ The weight given in this question is 7,056 kN , but we need the weight to be in Newtons for the formula to acc work. So converting  7,056 kN to newtons would give 7056000N. (Newton = Kilonewton * 1000)

Now all we need to do is compute these values-

M=  7056000/9.8

M=720000kg

Well, thats the ans

Answer:

20Kilowatt

Explanation:

Power is the rate of work done per time. It can be calculated using the formula:

Power = Energy/time

Energy = mass × acceleration due to gravity × height ÷ time

Power = mgh/t

Where;

m = mass (1000kg)

g = acceleration due to gravity (10m/s²)

h = height (10m)

t = time (s)

Power = 1000 × 10 × 10 ÷ 5

Power = 20000 watt

In kilowatt = 1000watt, the power is:

20Kilowatt or 20Kw

Answer:

0.1 L

Explanation:

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

Initial volume (V₁) = 0.05 L

Initial Pressure (P₁) = 207 KPa

Final pressure (P₂) = 101 KPa

Final volume (V₂) =?

We can obtain the new volume (i.e the final volume) of the gas by using the Boyle's law equation as illustrated below:

P₁V₁ = P₂V₂

207 × 0.05 = 101 × V₂

10.35 = 101 × V₂

Divide both side by 101

V₂ = 10.35 / 101

V₂ = 0.1 L

Thus, the new volume of the gas is 0.1 L

Answer:

I think It's induced magnet

Explanation:

Because a magnet and non magnet can be chicken nuggets

If a magnet causes the atoms in a non-magnetic metal to line up and act like a magnet, the non magnet is said to be an induced magnet by the magnetic induction by a permanent magnet.

A permanent magnet is made of ferromagnetic materials which are having permanent magnetic properties. The magnetic field lines from permanent magnet always align with an applied magnet.

As in the case of dipole molecules capable of inducing a polarity to a nonpolar molecule, a magnetic field by a strong magnet can induce a magnetic property to a nonmagnet.

The induced magnetic field only reside in the object as long as the induction source is there. For example the a rotating electric filed causes magnetic moment in a nonmagnet.

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.

The water hits the wall at a height of 5.38 m

Explanation:

Projectile Motion

It's the type of motion that experiences an object projected near the Earth's surface and moves along a curved path exclusively under the action of gravity.

The object describes a parabolic path given by the equation:

[tex]{\displaystyle y=\tan(\theta )\cdot x-{\frac {g}{2v_{0}^{2}\cos ^{2}\theta }}\cdot x^{2}}[/tex]

Where:

y   = vertical displacement

x   = horizontal displacement

θ   = Elevation angle

vo = Initial speed

The hose projects a water current upwards at an angle of θ=40° at a speed vo=20 m/s.

The height at which the water hits a wall located at x=8 m from the hose is:

[tex]{\displaystyle y=\tan40^\circ\cdot 8-{\frac {9.8}{2*20^{2}\cos ^{2}40^\circ }}\cdot 8^{2}}[/tex]

Calculating:

y = 5.38 m

The water hits the wall at a height of 5.38 m

Answer:1342

Explanation:

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.
