Explanation:

Answer: 300 J

Explanation:

Force = 150 KJ

Distance = 2.0 m

The minimum amount of work done by a hydraulic lift to raise a 150-kg aluminum block 2.0 meters vertically would be 2940 Joules, as the work done is the product of the force applied to the displacement of the object, therefore the correct answer is option B.

The total amount of energy transferred when a force is applied to move an object through some distance

The work done is the multiplication of applied force with displacement.

Work Done = Force × Displacement

As given in the problem we have to find out the minimum amount of work done by a hydraulic lift to raise a 150-kg aluminum block 2.0 meters vertically.

The minimum work done = 150 × 9.8 × 2

                                          = 2940 Joules

Thus, The minimum amount of work done by a hydraulic lift to raise a 150-kg aluminum block 2.0 meters vertically would be 2940 Joules.

Answer:

The answer is below

Explanation:

It has been observed that the strength of electromagnets is based on the electrical current passing through their wires.

However, the number of batteries can affect the strength of electromagnets if only the electromagnet's resistance is what's hindering the current.

This can be observed when multiple batteries are connected thereby increasing the degrees of voltage across the electromagnet.

The required work done will be "6000 kg-m".

Work would be defined as an object's displacement whenever a force would be exerted to that as well, whereas energy is defined as the capacity to accomplish the work.

This then exists throughout a variety of forms, including potential, kinetic, biochemical, thermodynamic, nuclear, as well as direct current.

According to the question,

Mass, m = 500 kg

Distance, d = 12 m

We know the formula,

→ Work = Force x Distance

or,

→ W = F x D

By substituting the given values in the above formula, we get

      = [tex]500\times 12[/tex]

      = [tex]6000[/tex] kg-m

Thus the above answer is correct.

Answer:

work done=392J

Explanation:

work done =Mgh

DATA

M=5kg

g= 9.8

h=8m

W=Mgh

W=5*9.8*8

W=392J

The work done by the gravitational force is equal to -400 J.

The gravitational force can be described as a force that attracts a body towards the center of the earth or any physical object that has mass. Every object has mass and exerts a gravitational pull on another object with mass.

Given, the mass of the container, m = 5 Kg

The height from the ground level, h = 8 m

The work done can be calculated by using the below-mentioned formula:

[tex]W = m\times g\times h[/tex]

Where g is the gravitational acceleration.

As the container is lifted in the upward direction therefore the value of the g will be negative.

Substitute the values of m, g, and h in the above formula:

W =  5 × (-10) × 8

W = -400 J.

The negative sign shows that the work is done against the gravitational force.

Therefore, the work done by the gravitational force is equal to -400 J.

Answer:

A

Explanation:

The correct answer is; The specific heat of water is greater than that of air.

The specific heat capacity of a substance is defined as the quantity of heat required to raise the temperature of a unit mass of that substance by 1°C.

The higher the specific heat capacity of a substance, the higher the energy required to raise its temperature by 1°C.

Water has a very high specific heat capacity compared to air therefore when air around a pool and the water in the pool receive equal amounts of energy from the sun, the air experiences a greater increase in temperature than does the water.

The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.

RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.

Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.

Answer:

Option D. 16 m/s

Explanation:

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

Initial velocity (u) = 0 m/s

Height (h) = 13 m

Acceleration due to gravity (g) = 9.8 m/s²

Final velocity (v) =?

We can determine how fast (i.e final velocity) the ball is traveling when it reaches the ground as illustrated below:

v² = u² – 2gh

v² = 0² – (2 × 9.8 × 13)

v² = 0 – 254.8

v² = 254.8

Take the square root of both side.

v = √254.8

v = 15.96

v ≈ 16 m/s

Thus, the ball is travelling with a velocity of 16 m/s when it reaches the ground

Answer:

[tex]2.33\ m/s^2[/tex]

Explanation:

Net Force

According to the second Newton's law, the net force exerted by an external agent on an object of mass m is:

Fn = m.a

Where a is the acceleration of the object.  The net force is the sum of the individual vector forces applied to the object.

The m=1500 Kg car has two horizontal forces applied: the forward force of 5000 N that causes the movement and the air resistance force of 1250 N that opposes motion.

The net force is Fn = 5000 N - 1500 N = 3500 N

To find the acceleration, we solve the equation for a:

[tex]\displaystyle a=\frac{Fn}{m}[/tex]

[tex]\displaystyle a=\frac{3500}{1500}[/tex]

[tex]\boxed{a = 2.33\ m/s^2}[/tex]

The car's acceleration is [tex]a = 2.33\ m/s^2[/tex]

Answer:

Vba = -20 m/s - 25 m/s = -45 m/s

Vab = 25 m/s + 20 m/s = 45 m/s

Explanation:

Relative Velocity

The relative velocity of object B with respect to object A (Vba) measures the velocity of B in the rest frame of object A.

It's calculated as:

Vba = Vb - Va

The velocity of car B is Vb=-20 m/s and the velocity of car A is Va=90 Km/h.

Converting Va to m/s:

Va = 90 Km/h * 1000/3600 = 25 m/s

Thus, the relative velocity of B with respect to A is:

Vba = -20 m/s - 25 m/s = -45 m/s

And the relative velocity of A with respect to B is:

Vab = 25 m/s + 20 m/s = 45 m/s

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.

Pollution

Climate change

Explanation:

The destruction of the coral reef can be attributed to pollution and climate change.

The pollution of the atmosphere by greenhouse gases such as carbon dioxide causes the average temperature of the planet to increase, a phenomenon that is referred to as global warming. Global warming also causes an increase in the temperature of sea waters which can lead to the death of microscopic algae, causing coral bleaching.

An increase in the concentration of carbon dioxide in the atmosphere also causes ocean acidification which, in turn, reduces the availability of materials required to form the calcium carbonate of the coral reef. In extreme cases, acidification of the ocean can cause the dissolution of the coral skeletons.
