How much current must be applied across a 60 Ω light bulb filament in order for it to consume 55 W of power? Unserious answers will be deleted, and reported. (Please show some work)
Answer: current I = 0.96 Ampere
Explanation:
Given that the
Resistance R = 60 Ω
Power = 55 W
Power is the product of current and voltage. That is
P = IV ...... (1)
But voltage V = IR. From ohms law.
Substitutes V in equation (1) power is now
P = I^2R
Substitute the above parameters into the formula to get current I
55 = 60 × I^2
Make I^2 the subject of formula
I^2 = 55/60
I^2 = 0.92
I = sqr(0.92)
I = 0.957 A
Therefore, 0.96 A current must be applied.

Which of the following is NOT an important component of planning ahead?
A figuring out necessary steps
B. setting plausible limits
C. constructing an inflexible plan
D. deciding what you want to accomplish
Answer: B setting plausible limits
Explanation: because when you are planning ahead you must only think how to do the thing correctly if you do all of your steps correctly you won't have any limitations.
Answer:
The correct answer is constructing an inflexible plan. Planning is a huge part in an individual’s life and also the life of a company. Though we want to plan for everything that could possibly happen, there needs to be flexibility as situations can change. Due to the fact planning can have a positive affect on a business for future happenings, it must also have variable and flexible room incase there are changes that need to be made.

An airplane moves in straight level flight at constant velocity. What is the
net force acting on it if the mass of the plane is 1000 kg and the frictional
drag of the air is 1800 N? *
Answer:
Net force = 0
Explanation:
We have, an airplane moves in straight level flight at constant velocity.
Mass of the plane is 1000 kg
The frictional force acting of the air is 1800 N.
It is required to find the net force acting on it. We know that net force is given by the product of mass and acceleration. But here the airplane moves with constant speed, it means its acceleration is equal to 0 such that net force is equal to 0.

What is Wien's displacement law ?Wien's displacement law states that, the black-body radiation curve for different temperatures will have different peaks of wavelengths and the wavelength is inversely proportional to the surface temperature.
Here,
According to Wien's displacement law,
The wavelength of the star is inversely proportional to its surface temperature.
λ [tex]\alpha[/tex] 1/T
where T is the surface temperature.
Therefore, the star with lowest wavelength will have the highest surface temperature.
Consider the wavelengths of each stars given,
The increasing order of their wavelengths can be written as,
λ(Orange) > λ(Yellow) > λ(White) > λ(Blue)
Therefore the increasing order of their surface temperatures will be,
T(Blue) > T(White) > T(Yellow) > T(Orange)
Hence,
The order of the surface temperature of the stars, starting from the highest to the lowest is Y > X > W > Z.

As a ball is thrown into the sky, potential energy increases and kinetic energy decreases. But, the mechanical energy ( that is the sum of the potential and kinetic energy) remains the same....
A girl is bouncing on a trampoline where is her gravitational potential energy a maximum and where is her kinetic energy maximum
Answer:
When you jump down, your kinetic is converted to potential energy of the stretched trampoline. The trampoline's potential energy is converted into kinetic energy, which is transferred to you, making you bounce up. At the top of your jump, all your kinetic energy has been converted into potential energy. Right before you hit the trampoline, all of your potential energy has been converted back into kinetic energy. As you jump up and down your kinetic energy increases and decrease.

In a science experiment showing the splitting of water into Oxygen and hydrogen, two inverted test tubes of water were placed over the site of the reaction. (see the pic) How can you tell which one was catching the oxygen and which one was catching the hydrogen?
The hydrogen is a positive ion and will be located close to the negative terminal of the battery.
The oxygen is a negative ion which will be located next to the negative terminal of the battery.
There are 2 hydrogen atoms for every oxygen atom. The hydrogen will take up more space and is pushing the water lower in the test tube.
The hydrogen, being a smaller atom, will take up less space than the oxygen. It will push the water down less.
Answer:
There are 2 hydrogen atoms for every oxygen atom. The hydrogen will take up more space and is pushing the water lower in the test tube.
Explanation:
Electrolysis refers to the decomposition of a solution (electrolyte) owing to the passage of direct current through the solution.
Water is decomposed into its constituents; hydrogen and oxygen by electrolysis. However, a battery is connected to drive the process and other electrolytes such as dilute acids are added to improve the conductivity of water.
In the electrolysis of water, two moles of hydrogen gas is produced for each mole of oxygen gas produced. Hence the ratio of hydrogen to oxygen gas produced is 2:1 by volume. This implies that the space occupied by oxygen is half the space occupied by hydrogen. The hydrogen will thus occupy more space, pushing the water much lower than oxygen.

Traveling in circle requires a net force
Answer:
Circular motion requires a net inward or "centripetal" force. Without a net centripetal force, an object cannot travel in circular motion. In fact, if the forces are balanced, then an object in motion continues in motion in a straight line at constant speed.
