Answers

Answer 1

Answer: If an object is moving or at work, it is considered to be a particle with kinetic energy. In physics, kinetic energy is thought to be the energy of motion, it is an acquisition of energy of an object through the possession of motion. Other forms of kinetic energy are vibration, rotation, and translation.

Answer 2

Answer:

Answer:

As a person pushes a box across a floor, the energy from the person’s moving arm is transferred to the box, and the box and floor become warm. During this process, energy is conserved.

A ball with a mass of 1.5 kilograms is tied to the end of a rope. The ball is pulled to a height of 0.5 meters above the ground and released.The ball has joules of potential energy at position B. At position A, all of the energy changes to kinetic energy. The velocity of the ball at position A is meters/second. Assume there’s no air resistance. Use g = 9.8 m/s2 , PE = m × g × h, and

Answers

Solve the potential energy at point B

PE = mgh

Where m is the mass

G is the acceleration due to gravity 9.8 m/s2

H is the height

PE = ( 1.5 kg) ( 9.8 m/s2) (0.5 m)

PE = 7.35 J

Solve the velocity using the

KE = 0.5mv^2

Where ke is the kinetic energy

M is the mass

V is the velocity

Since all energy is converted to KE

So KE = PE

7.35 = 0.53(1.5) v^2

V = 3.13 m/s

The velocity of the ball at position A is equal to 3.13 m/s.

Given the following data:

Mass of ball = 1.5 kilograms.

Height = 0.5 meters.

Acceleration due to gravity = 9.8 $m/s^2$

How to calculate potential energy.

Mathematically, potential energy is given by this formula:

$P.E = mgh\n\n$

Where:

m is the mass.

h is the height.

g is acceleration due to gravity.

Substituting the given parameters into the formula, we have;

$P.E = 1.5 * 9.8 * 0.5$

P.E = 7.35 Joules.

Assuming there’s no air resistance, the potential energy would be equal to kinetic energy.

$P.E = K.E\n\n7.35 = (1)/(2) mv^2\n\nmv^2 = 7.35 * 2\n\n1.5v^2 = 14.7\n\nv=\sqrt{(14.7)/(1.5) } \n\nv=√(9.8)$

V = 3.13 m/s.

Ammonia is a weak base because produce ____ ion in solution?

Answers

ammonia is a weak base ( electrolyte) because ammonia reacts with water to produce ammonium and hydroxide ions. When hydroxide ion reacts with ammonium, it results to water and ammonia. it only proves that ammonia is rather a base because of its acceptance of hydrogen ion from water.

Ammonia is a weak base because it produces hydroxide (OH-) ions in solution.

Why is ammonia a weak acid?

Ammonia is a weak base because it produces hydroxide ions (OH-) in solution.

When ammonia dissolves in water, it accepts a proton from water, forming the ammonium ion (NH4+), and leaves hydroxide ions behind. This partial dissociation results in a small concentration of hydroxide ions, causing the solution to be slightly basic.

Unlike strong bases, which fully dissociate and release a large number of hydroxide ions, ammonia's limited ability to produce hydroxide ions makes it a weak base.

What is the motion of a body when only the force of gravity is acting on it

Answers

When only the force of gravity acts on an object,
the situation is called "free fall".

The motion is uniformly accelerated. The object falls
straight toward the center of the other object in whose
gravity it shares, and its speed increases at a constant
rate.

When this happens on or near the surface of the Earth,
the rate is (9.8 meters per second greater) for each
second of falling.

True free-fall is never observed in daily life. Whenever
we see an object falling, it is always falling through air,
which counteracts the force of gravity to a greater or
lesser degree, depending on the object's size, shape,
weight, surface texture, and speed through the air.

Photosphere, convective zone, radiative zone
Convective zone, chromosphere, corona
Radiative zone, corona, convective zone

Answers

The Photosphere, Chromosphere, Transition Region, and Corona are the outer layers. Option A is correct.

What are the layer of sun?

Corona, photosphere, chromosphere are the layers of the sun in the correct order from innermost to outermost.

The distance is measured from the sun's core for the inner layers and from the sun's surface for the outer layers. The Core and Convection Zone, are the inner layers.

The Photosphere, Chromosphere, Transition Region, and Corona are the outer layers.

Hence, option A is correct.
