Speed (often abbreviated as "s") is a scalar variable that describes how much an object's location changes over time or how much it changes per unit of time. The average speed of an item in a period of time is the distance traveled by the object divided by the duration of the period.

Time divided by distance are the speed-related metrics.. The meter per second (m/s) is the SI unit of speed, while the kilometer per hour (kph) is the most often used unit of speed in daily life.

Avrage acc= ◆velocity/ ◆Time

Av acc =25-10/6-0

Av acc = 15/6= 2.5 m/s^2

The final kinetic energy will it have just before hitting the ground is 5.8755 KJ.

Mass of the ball, M = 40 kg

Height of the ledge, S = 15 m

Initial velocity, u = 0 m/s (at rest)

Using equation of motion we get,

V² = u² + 2aS

V² = 0 + 2 × 9.8 × 15

V² = 294

v = 17.14m/s

kinetic enrgy is calculated as :

E = 1/2 × mass × v²

for initial velocity (u =0) kinetic energy is

E = 1/2 × 40 × 0²

E = 0J

for final velocity (v) kinetic energy is :

E = 1/2 × 40 × (17.14)²

E = 5,875.5 J

E = 5.8755 KJ

The final kinetic energy will it have just before hitting the ground is 5.8755 KJ.

Answer:

Explanation:

To start with, an electric generator uses an A.C circuit power supply which means the current alternates throughout. Firstly, the magnetic field/direction produced by the magnets (N-pole and S-pole) cause the rectangular coil between to turn (you can figure out the direction of the force and current using Fleming's Right Hand Dynamo rule). Alongside, as the coil turns, it cuts through the produced magnetic field by the magnets to induce E.M.F (electromotive force) and then the voltage/current travels to the secondary coil where it is either stepped up or down as needed hence transforming the input voltage.

The calculated magnitude of force is 47.04 N. Second Law of Motion by Newton (Force) An object's acceleration is determined by its mass and the force being applied.

All objects on Earth experience weight, or a gravitational pull that is proportionate to their mass and is imposed by the planet's mass. The acceleration that gravity gives to objects falling freely serves as a gauge of its strength. The acceleration of gravity at Earth's surface is approximately 9.8 meters (32 feet) per second every second. The magnitudes of the object's weight and the normal force are equal when the object is resting on a horizontal surface and there are no other vertically acting forces; that is, Therefore, the normal force in this case is 26 N, which is much greater than the box's weight.

The CO2 molecules move at a root-mean-square speed of 339 m/s.

CO2 molecules have an average kinetic energy of 4.2 x 1021 J.

Kinetic energy is a property of motion that an object or particle can employ to move. An object accelerates and acquires kinetic energy when work is done by applying a net force, which transfers energy.

When an object is moving, it has kinetic energy. If we want to accelerate any item, a force must be applied. Applying force requires effort on our part. Once the process is complete and energy has in fact been transferred to the item, it will be travelling at a new constant speed.

Answer: Yes

Explanation: The block moves a distance d under the influence of the force, so work is done by the force. Note that since the object is not accelerating, there is another force present, most likely friction.

b.

Ignoring the Friction, the Acceleration of the block would be 2 [tex]ms^{-2}[/tex].

The relation of force with mass and acceleration is given by :

Force = Mass  *  Acceleration

Here the Force is 10N and the mass of the block is 5 Kg so substituting the values in the formula we get

Acceleration =  [tex]\frac{Force}{Mass}[/tex]  =  [tex]\frac{10}{5}[/tex] = 2 [tex]ms^{-2}[/tex] .

What is force-

According to physics. A force can cause an object with mass to accelerate when it changes its velocity, for as when it moves away from rest. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction. It is calculated using the newton SI unit (N). Force is denoted by the letter F. (formerly P).

b) 1.0 seconds is  50.1 m.

c) 1.5 seconds is 45.475 m.

d) 2.0 seconds is 30.4 m.

Given parameters:

Height of the tower; h₀ = 60 m.

Initial velocity, u = 5 m/s.

We know that,

acceleration due to gravity, g = 9.8 m/s².

applied formula is :

h = h₀ - ( ut + 1/2gt²)

a)So, stone's position from the ground after:

.5 seconds:

h = h₀ - ( ut + 1/2gt²)

= 60m - ( 5*0.5 + 1/2*9.8*0.5²) m

= 56.275 m.

b)So, stone's position from the ground after:

1.0 seconds:

h = h₀ - ( ut + 1/2gt²)

= 60m - ( 5*1.0 + 1/2*9.8*1.0²) m

= 50.1 m.

c)So, stone's position from the ground after:

1.5 seconds:

h = h₀ - ( ut + 1/2gt²)

= 60m - ( 5*1.5 + 1/2*9.8*1.5²) m

= 45.475 m.

d)So, stone's position from the ground after:

2.0 seconds:

h = h₀ - ( ut + 1/2gt²)

= 60m - ( 5*2.0 + 1/2*9.8*2.0²) m

The relative ability of a bonded atom to attract shared electron pairs is called its electronegativity. This ability increases as the size of the atom decreases because for a smaller atom the shared electrons will be closer to the nucleus.

The electronegativity of an atom is a measure of how strongly it attracts electrons to itself. The higher the electronegativity of an atom, the more it will pull electrons away from other atoms.The electronegativity of an atom increases as the size of the atom decreases. This is because the electrons are closer to the nucleus in a smaller atom, and the nucleus has a greater pull on the electrons.

The electronegativity of an atom also depends on the number of protons in the nucleus. The more protons an atom has, the greater the electronegativity. Electronegativity is an important property in determining the chemical properties of atoms and molecules. Atoms with high electronegativities will tend to form bonds with other atoms that have low electronegativities. This is because the high electronegativity atom will pull the electrons away from the other atom, making the bond between the two atoms stronger.

The electronegativity of an atom is determined by the ability of the atom to attract electrons to itself. The higher the electronegativity of an atom, the more it will pull electrons away from other atoms.The size of an atom plays a role in its electronegativity. Smaller atoms have a higher electronegativity than larger atoms because the electrons are closer to the nucleus. This means that the smaller atom can more easily pull electrons away from the larger atom.

The trend in electronegativity is that it increases as you go from left to right across the periodic table. This is because the atoms get smaller as you go from left to right. The smaller atoms have a higher electronegativity than the larger atoms.The trend in electronegativity is also that it increases as you go from bottom to top of the periodic table.

The calculated answer is 2α. You must (a) increase the angular acceleration in order to increase the moment of inertia of a body about an axis.

The rotational rate of the body, measured in radians per second, is used to define the angular velocity of a rotating body about a fixed axis as (rad/s). In linear kinematics, force is what drives an object's acceleration. Similar to this, an angular acceleration is brought on by torque. As a result, torque can be thought of as the rotational counterpart to force. The force that can cause an object to rotate along an axis is measured as torque.

X will lift faster and easier than Y because of X lift with maximum speed with minimum energy consumption.

First we have to find from that we get to know that which windlass will lift faster,

For windlass X,

Torque(X)=weight x radius of drum

                 =50x9.81x0.25=122.625 Nm

Torque (Y)=weight x radius of drum

                  =50x9.81x0.375=183.93 Nm

As we know that,

Equation of Power= Torque x Angular velocity

And Angular velocity (w)= 2 x pi x N/60

Therefore Torque is inversely proportional to speed. Thus, when speed of the car is increasing , decreaseing of torque will start.According to above sentence ,windlass X have maximum speed of lift and windlass Y have comparatively low speed.Also power is directly proportional to Torque, so maximum torque used maximum energy and vice versa.

Therefore X lift with maximum speed with minimum energy consumption.

A car retains a pace of 20 meters according to second because it acts in a straight line for five seconds and is in consistent motion.

An object has a consistent speed while both the value and direction of the charge at which such an object is changing its role continue to be steady. In different words, for an object to have consistent speed, its movement has to no longer alternate guidelines through the years and the object should have steady speed as properly.
