A turntable A is built into a stage for use in a theatrical production. It is observed during a rehearsal that a trunk B starts

Helga [31]

Answer:

μ = 0.03

Explanation:

In order for the trunk not to slide the frictional force between the turntable and the trunk must be equal to the unbalanced force applied on the trunk by the motion of the turntable. Therefore,

Unbalanced Force = Frictional Force

but,

Unbalanced Force = ma (Newton's second law of motion)

Frictional Force = μN = μW = μmg

Therefore,

ma = μmg

a = μg

μ = a/g

where,

μ = coefficient of static friction between the trunk and the turntable = ?

a = tangential acceleration of trunk = 0.3 m/s²

g = 9.8 m/s²

Therefore,

μ = (0.3 m/s²)/(9.8 m/s²)

Calculate the size of the magnetic field 20 m below a high voltage power line. The line carries 450 MW at a voltage of 300,000 V

Stells [14]

Answer:

$1.5 \times 10^{-5} \mathrm{~T}$ .

Explanation:

Power carried by the line $=P=450 \mathrm{MW}=450 \times 10^{6} \mathrm{~W}$

Voltage across the line Volts

Current flowing in the line =i

Size of magnetic field =B

Distance from the line

Formula Used:

Current flowing is given as

$i=\frac{P}{\Delta V}$

Magnetic field by the current carrying wire is given as

$B=\left(\frac{\mu}{4 \pi}\right)\left(\frac{2 i}{r}\right)$

Inserting the values

$B=\left(10^{-7}\right)\left(\frac{2(1500)}{(20)}\right) \\
B=1.5 \times 10^{-5} \mathrm{~T}$

Conclusion:

Thus, the magnetic field comes out to be $1.5 \times 10^{-5} \mathrm{~T}$ .

How can you prevent static sparks while filling your boat's fuel tank?

dangina [55]

To prevent static sparks that could occur while you fill fuel is that, a person who is filling the tank should remember that the nozzle of the fuel pump hose should always be in connected or in contact to the tank. This will prevent static sparks from happening to the boat that is going to be used and prevent harm to the person using or refilling the fuel.

Flowchart symbols

MArishka [77]

Answer:

Option (A)

Explanation:

A flowchart can be described as a representation of a process or an algorithm in a sequential manner (stepwise) in the form of diagrams. These steps are made of symbols that are connected to one another with the help of arrows. These arrows are used to show the direction of the process.

There are mainly four symbols that are used to describe a flow chart, which includes-

Oval or Pill Shape- This type of symbol is used to depict the start or the end of a process.

Rectangle Shape- This type of symbols is used to describe the process .

Diamond Shape- This type of symbol is used to represent decision s.

Parallelogram- This type of symbol is used for the representation of an input or an output.

Thus, the correct answer is option (A).
