What happens if there is no transformation of energy in the world ?
Answer:
If there were no transformation of energy in the world, everything would come to a standstill.
Explanation:
Energy is required for all processes and interactions to occur, including movement and chemical reactions. Without energy, matter would not be able to move or change in any way. This would mean that living organisms would not be able to survive, as they rely on energy to carry out metabolic processes and maintain their body's functions.
The sun would not shine, the wind would not blow and the water would not flow, as they are all driven by energy transformations. The weather would not change, and there would be no seasons. The temperature would not vary and the weather patterns would not change.
Machines and technology would not work, as they also rely on energy to operate. There would be no electricity, transportation, or communication. The economy would come to a standstill as all the industry, trade, and commerce would stop.
In short, without energy transformation, the world would be a static, lifeless place, and life as we know it would not be possible.

A sculptor uses a constant volume of modeling clay to form a cylinder with a large height and a relatively small radius. The clay is molded in such a way that the height of the clay increases as the radius decreases, but it retains its cylindrical shape.

A sculptor uses a constant volume of modeling clay to form a cylinder with a large height and a relatively small radius.

At time t=c, the height of the clay is 8 inches, the radius of the clay is 3 inches, and the radius of the clay is decreasing at a rate of 12 inch per minute. The expression for the rate of change of the radius of the clay with respect to the height of the clay in terms of height h and radius r is dr/dh =- r/2h
The following formula determines a cylinder's volume:
V = πr²h,
where V is the volume, r is the cylinder's radius, and h is the cylinder's height.
In terms of height h and radius r, we must express the rate at which the clay's radius changes in relation to its height.
That means that height h and radius r are used to express dr / dh. To accomplish this, we must first compare the volume to the height, or find dV / dh:
V = πr²h
dv/dh = d/dh ( πr²h)
dv/dh =πr²+2 πrh dr/dh
The volume constance dV/dh = 0
dv/dh =πr²+2 πrh dr/dh
0=πr²+2 πrh dr/dh

dr/dh = - -πr² / 2 πrh

if there are two waves A and B with their amplituds 3 cm and 4 cm respectively compared it's loudness and tell which one is more louder
Wave B will be louder than wave A.
Let the amplitude of wave A be a1 and the amplitude of wave B be a2.
Similarly, let the loudness of wave A be L1 and the loudness of wave B be L2.
We know,
[tex]\frac{L1}{L2}[/tex] = [tex]\frac{a1^{2} }{a2^{2} }[/tex]
By substitution we see:
[tex]\frac{L1}{L2}[/tex] = [tex]\frac{3^{2} }{4^{2} }[/tex]
We get:
[tex]\frac{L1}{L2}[/tex] = [tex]\frac{9}{16}[/tex] .

The speed of countershaft drive gear is 225 RPM. To find it, you have to compare both STM value.
How to calculate the speed of that countershaft drive gear?To calculate the the speed of countershaft drive, we use the formula of the surface teeth per minute (STM) where the formula is:
the surface teeth per minute (STM) = Speed x number of teeth
Because of the main drive gear is connected with the countershaft drive gear, the STM of both are equivalent. So.
Main gear speed x Main gear number of teeth = countershaft speed x countershaft number of speed

Figure 4 shows balls 1 and 2 before and after a collision.
Ball 1 initially travels with a velocity of u m/s. Ball 2 is stationary and has a mass of 0.2 kg.
Ball 1 collides with ball 2 and this collision lasts for 0.1 s. Afterwards, both balls move in
the direction of ball 1's initial velocity. Each ball has a different final velocity.
During the collision, a force of -6N is exerted on ball 1 by ball 2
Calculate the velocity of ball 2 after the collision
According to the question, the velocity of ball 2 after the collision is 30 m/s.
What is velocity?
Velocity is a vector quantity that describes the rate and direction of an object's motion. It is the displacement of an object over a period of time and is usually expressed in terms of distance (meters, feet, or kilometers) divided by time (seconds). It can also be expressed as the speed of an object in a particular direction. Velocity is a key factor in describing the motion of objects, as it accounts for both the speed and direction of an object's motion. It is an important concept in physics, and it is used to calculate forces and potential energy.
From the laws of conservation of momentum, the final velocity of ball 2 can be calculated as follows:
m1u + m2v = m1v1 + m2v2
0.2 x u + 0.2 x v = 0.2 x u + 0.2 x v2
v2 = u - (6N x 0.1s)/0.2kg
v2 = u - 30 m/s

Answer:
W = - 16450 J
Explanation:
Force of friction = - 329 N ( Friction acts opposite to the direction of motion )
Displacement = 50 m
W = F s
= - 329 × 50
W = - 16450 J
∴ The work done by the force of the friction is - 16450 J .
The work done on the car to stop it by the frictional force of 329 N over 50 m is 16450 J.
What is frictional force?Friction is a type of force which resists the motion of an object. Thus friction opposes the force that make the object moving. When a force is making a displacement on object or make it stop.
The work done in physics is the product of the force acting on it to stop or displace and the displacement.
Given displacement = 50 m
friction force = 329 N
Work done = Force × displacement
