58775.51 J kinetic energy is lost,
Energy lost = 0.5*mv²
= 0.5*8000/9.8 * 12*12
= 58775.51 J
To calculate the energy loss of a moving object, subtract the initial kinetic energy from the final kinetic energy, where the initial and final kinetic energies are calculated using the formula 1/2*M*V^2.
When energy is transformed from one form to another or moved from one area to any other, or from one device to another there's energy loss. This means whilst energy is converted to a different form, some of the entering energy is become an especially disordered form of energy, like heat.

Explanation:
<u>Dynamics of System of Masses</u>
We are given the characteristics of a system where two masses are connected by a massless string. The acceleration under these conditions is common to both objects. By analyzing the acting forces on each mass, we can find both the common acceleration and tension of the string.
Let's analyze the forces acting upon mass m1: To the right, we have the tension of the string that tries to move it in that direction. Opposite to the intent to move is the friction force to the left. Applying the Newton's second law, we have
Where
Thus
Now for the mass m2, in the vertical direction
Note that the sign of the acceleration is downwards since the mass m1 tends to move to the right and both masses are tied. W2 is the weight of the mass 2, thus
Replacing the value of T obtained above
Solving for a
Plugging in the given values:
Computing the tension of the string
Answer: Covalent Bonds or Covalent Bonding Electrons
Explanation:
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
Hi lamy
we know ΔU=qΔV
solving for potential difference ΔV
we get ΔV=ΔU/q
ΔV= (Ub-Ua)/q
Ub is potential energy at b
Ua is potential energy at a
q is the charge of the particle
plug in and find out
Answer:
The increase in amount of ozone layer in stratosphere, will be beneficial in preventing the intense and harmful radiations, such as Ultra Violet Rays, to reach the surface of earth.
Explanation:
Ozone layer is formed when a single atom of oxygen (O) reacts with a molecule of oxygen (O₂) to form O₃ (Ozone). The ozone layer in the stratosphere is formed by the reaction of oxygen molecule (O₂) with a single atom of oxygen (O), which is formed by splitting up of an oxygen molecule, by the sunlight.
This ozone layer in stratosphere absorbs harmful radiations, such as Ultra Violet Rays and prevents them to reach the earth. If these rays reach the surface of earth, they can cause life damage to human bodies.
<u>Thus, the increase in amount of ozone layer in stratosphere, will be beneficial in preventing the intense and harmful radiations to reach the surface of earth.</u>
