Any form of stored energy is called ______ energy
what is in the blank
Answer: Potential energy
Explanation:
Any form of stored energy is called potential energy. (option b)
Potential energy can come in various forms. Gravitational potential energy is associated with an object's position concerning the Earth's gravitational field. The higher the object, the more potential energy it possesses. Elastic potential energy is stored in objects like springs or rubber bands when they are compressed or stretched. Chemical potential energy is stored in the bonds between atoms and molecules in substances like food or fuel.
Remember, potential energy is a concept that helps us understand the ability of an object or a system to perform work or change its state based on its position or condition.
Hence the correct option is (b).

10. When a car turns, its front wheels do not turn by the same amount. In order that the car turn around a common point, the wheel on the side to which the car is turning, turns more than the other. Which of these correctly shows the alignment of a car's wheels when it is turning to its right?
Answer:
The front wheels are aligned towards the right.
Explanation:
Wheel alignment is very important. It ensures proper maintenance of the car's wheel. When a car turns around a common point, the wheel on that side to which the car turns, the turning is more than the other.
The wheel alignment consists of adjusting the wheel's angles so as to stay perpendicular to the surface of the road and to ensure proper tract to the tires. It also provides maximum life to the tire. The front wheels are aligned to the right when the car makes a right turn and the wheel leans in towards the center of the car.

is given
to the work done
per conlomb of charge
passing between two points?
Electric potential difference is named to the work done per coulomb of charge passing between two points.
What is electric potential?An object's electrical potential energy is determined by two factors: the charge the thing carries internally, and the position of the object in relation to other electrically charged objects. The amount of effort required to move an object from one location to another against an electric field determines the strength of the electric potential.
The total potential energy that a unit charge would have if it were positioned everywhere in space is known as electric potential energy.
The energy gained when an object moves against an electric field is known as the electric potential energy. The electric potential is calculated for any charge by dividing the potential energy by the charge.

How far does an object travel if it starts from rest and accelerates at a rate of 2.0 meters per second2 for 6.5 seconds?
Answer:
42.25 m
Explanation:
According to the question;
u = 0 m/s (journey started from rest)
a = 2 m/s^2
t = 6.5 secs
Given that;
s = ut + 1/2at^2
s = (0 * 6.5) + 1/2 * 2 * (6.5)^2
s = 0 + 42.25
s = 42.25 m

Answer:
D. The General Adaptation Syndrome
Explanation:
Hans Selye, an endocrinologist, developed the "Stress Theory." He showed the relationship of "stress" to the person's development of disease.
Under stress, a person's body experiences changes. The person tries to cope with these through three stages: Alarm Reaction Stage, Resistance Stage and Exhaustion Stage. It is at the last stage that a person's immune system is placed at a huge risk. Once the person is exposed to a stressor for a period of time, he becomes hopeless and his body tends to give up coping. He then succumbs to stress-related illness.
A 1232 kg car moving north at 25.6 m/s collides with a 2028 kg car moving north at 17.5 m/s . They stick together. In what direction and at what speed do they move after the collision?
Answer:
I. Angle = 41.7° Northeast.
II. Vr = 7.08m/s
Explanation:
Let the two cars be denoted by A and B
Given the following data;
Mass of car A = 1232 Kg
Velocity of car A = 25.6 m/s
Mass of car B = 2028 Kg
Velocity of car B = 17.5m/s
First of all, we would solve for momentum;
Momentum = mass × velocity
Momentum, M1 = 1232 × 25.6
Momentum, M1 = 31539.2 Kgm/s
Momentum, M2 = 2028 × 17.5
Momentum, M2 = 35490 Kgm/s
Now, let's find the resultant momentum using the Pythagoras theorem;
R² = M1² + M2²
R² = 31539.2² + 35490²
R² = 994721136.6 + 1259540100
R² = 2254261237
Taking the square root of both sides, we have
Resultant momentum, R = 47479.06 Kgm/s
To find the direction;
Angle = tan¯¹(M1/M2)
Angle = tan¯¹(31539.2/35490)
Angle = tan¯¹(0.89)
Angle = 41.7° Northeast.
To find the speed;
R = (M1 + M2)Vr
47479.06 = (31539.2 + 35490)Vr
47479.06 = 67029.2Vr
Vr = 47479.06/67029.2
Vr = 7.08m/s

Please show the work and steps. The answer is (3.3 s, 15 m/s)
Answer:
t = 3.3 s and V = 15 m/s
Explanation:
Given that,
Distance covered by the car, d = 50 m
Initial speed, u = 5 m/s
Final speed, v = 25 m/s
Firstly we can find the acceleration of the car using third equation of motion. i.e.
[tex]v^2-u^2=2as\\\\a=\dfrac{v^2-u^2}{2d}\\\\a=\dfrac{(25)^2-(5)^2}{2(50)}\\\\a=6\ m/s^2[/tex]
Let t is the time taken by the car to occur this.
[tex]t=\dfrac{v-u}{a}\\\\t=\dfrac{25-5}{6}\\\\t=3.3\ s[/tex]
Let v is the average velocity of the car. It can be calculated as follows :
[tex]V=\dfrac{u+v}{2}\\\\V=\dfrac{25+5}{2}\\\\V=\dfrac{30}{2}\\\\V=15\ m/s[/tex]
So, the time taken by the car to occur this is 3.3 seconds and the average velocity of the car is 15 m/s.

Why can a device never be 100% efficient? Explain.
Answer:
No machine is free from the effects of gravity, and even with wonderful lubrication, friction always exists. The energy a machine produces is always less than the energy put into it (energy input). ... That is why 100% efficiency in machines shall not be possible.
Answer:The output work is always less than the input work because some of the input work is used to overcome friction. Therefore, efficiency is always less than 100 percent.

what should be angle between force and displacement to get the maximum work
Answer:
0°
Explanation:
The angle between force and displacement should be 0° in order to get the maximum work done.
Work done = Force x dcosФ°
Ф is the angle between force and displacement
When Ф is zero, the maximum work done is attained
When Ф is 90, the minimum work is done, in fact, work done is 0

Four atoms of hydrogen combine with one carbon atom to form CH4, but only two hydrogen atoms combine with one oxygen atom to form H2O. Which of the following helps to explain why?
Hydrogen has one valence electron.
Oxygen has two vacancies in its electron shell, but carbon has four vacancies.
Metallic bonds form between positively charged metal ions and delocalized electrons.
Atoms may share electrons in order to fill their electron shells.
Answer:
Oxygen has two vacancies in its electron shell, but carbon has four vacancies.
Explanation:
Oxygen has vacant space for two electrons in its outermost shell. Hence, it can accommodate two electrons from two hydrogen atoms. This leads to the formation of the H₂O molecule. On the other hand, the Carbon atom has vacant space for four electrons. Hence, it can accommodate four electrons from four hydrogen atoms. This leads to the formation of the CH₄ molecule.
In this way the explanation can be provided by the following statement:
Oxygen has two vacancies in its electron shell, but carbon has four vacancies.
Answer:
-Atoms may share electrons in order to fill their electron shells.
- Hydrogen has one valence electron.
- Oxygen has two vacancies in its electron shell, but carbon has four vacancies.
