Answer:
4E
Explanation:
4E
Explanation:
From the question given above, the following data were obtained:
Initial elongation (e₁) = 4 cm = 4/100 = 0.04 m
Initial energy (E₁) = E
Final elongation (e₂) = 0.04 + 0.04 = 0.08 m
Final energy (E₂) =?
The energy stored in a s spring is given by:
E = ½Ke²
Where
E => is the energy
K => is the spring constant
e => is the elongation
From:
E = ½Ke²
Energy is directly proportional to the elongation. Thus,
E₁/e₁² = E₂/e₂²
With the above formula, we can obtain the final energy as follow:
Initial elongation (e₁) = 0.04 m
Initial energy (E₁) = E
Final elongation (e₂) = 0.08 m
Final energy (E₂) =?
E₁/e₁² = E₂/e₂²
E / 0.04² = E₂ / 0.08²
E / 0.0016 = E₂ / 0.0064
Cross multiply
0.0016 × E₂ = 0.0064E
Divide both side by 0.0016
E₂ = 0.0064E / 0.0016
E₂ = 4E
Therefore, the final energy is 4 times the initial energy i.e 4E
Answer:
4e is the answer

Which of the following is a clear indicator that the tire is at the end of its legal life?
Select one:
A. Out-of-Balance Conditions
B. Tread depth above the level of built-in wear indicators
C. Low tire pressure
D. Tread depth below the level of built-in wear indicators
Answer:
Option D, Tread depth below the level of built-in wear indicators
Explanation:
The legal life of tire is checked by looking out for tread wear indicators. In general, tread wear indicators are nothing but small bars of width of 5 mm. These bars are built in the main grooves of the tires.
If the tire tread is at the top level of the tread wear indicating bar, then it means that tires have reached the legal limit of tire death (1.6 mm)
Hence, option D is correct

The following are the hazards associated with portable ladders are:
A) Ladder is not positioned correctly
C) Ladder is not tied off correctly
D) Unsteady ladder
What are portable ladders?Portable ladders are those ladders that can be folded and light weighted and made up of plastic or steel. They are portable to be used in homes and indoors.
They are easy to transport and easy to work with because they are lightweight, and they take less space to put them. But as they are lightweight, they will easily fall down.
They contain support behind them, they don't need to tie down and need support, so there are chances of being it unsteady.
Thus, the hazards associated with portable ladders are:
A) Ladder is not positioned correctly
C) Ladder is not tied off correctly
D) Unsteady ladder

When you accelerate, the size of the front tire patch becomes____
Answer:
Larger
Explanation:
When a vehicle is accelerated, the weight of the vehicle and the driver is transferred to the front of the rear of the car.
This transferred weight is nothing but the additional weight that presses the car's suspension in the downward direction thereby affecting tire contact patch in the rear due to which the rear tires loses adhesion.
When you accelerate, the size of the front tire patch becomes larger.
It should be noted that to develop the power to accelerate quickly, an internal combustion engine is vital. When a vehicle is accelerated, the weight of the vehicle and that of the driver will be transferred to the front of the vehicle.
Therefore, when you accelerate, the size of the front tire patch becomes larger since the transferred weight is additional weight.

How is gravitational energy converted into other forms
Answer:
Gravitational potential energy is energy due to an object's position. An object in the air has gravitational potential energy because when released, it will begin to move and convert its stored energy into movement, or kinetic energy. ... Other forms include thermal energy, which we know as heat, and sound.

which statement regarding vessel maintenance is true?
A- When storing a vessel for a long time, it is best to keep it in the sun and uncovered
B- when cleaning a vessel, use regular household detergents and cleaners
C- When replacing electrical parts on a vessel, never use automotive parts
D- When preparing your vessel for cold weather, use antifreeze that contains ethylene glycol
The true statement is that when a person is person is preparing their vessel for cold weather, then it's important to use antifreeze which contains ethylene glycol.
During cold weather, it's common for vessels to have their parts or engine frozen due to the weather.
The freezing of the engine can lead to an accident or spoil the vessel. Therefore, it is advisable to use ethylene glycol since it's an antifreeze and using it can prevent an accident or spoilage of the parts of the vessel.
Therefore, the correct option is D.
