1. A sailboat accelerates uniformly from 3.0 m/s to 12.0 m/s at a rate of 1.5 m/s2. What distance does the boat travel?​

Answers

Answer 1

Answer:

45 m

Explanation:

Use the equations of motion.

We know that:

S= the unknown

U=3 m/s

V=12 m/s

A=1.5 m/s

T= we won't need it

The equation used: [tex]v^2=u^2+2as[/tex]

Subsitute the values: [tex]12^2=3^2+2*1.5*s\\[/tex]

Solve the equation:

[tex]144=9+3s[/tex]

[tex]135=3s[/tex]

[tex]s=45 m[/tex]

Answers

Answer:

' In layman's terms, the k variable in Hooke's law (F = -kx) indicates stiffness and strength. The higher the value of k, the more force is needed to stretch an object to a given length. This value is dependent on the object's material alongside its shape and Proportons

by the formula, S=ut+½at².

S=[166×8.6+½.×9.8×(8.6)²]. ...by calculation

S = 1427.6+362.404

S=1790.004m

what supports a white dwarf against the crush of gravity?

Answers

Answer:  In particular, electron degeneracy pressure is what supports white dwarfs against gravitational collapse, and the Chandrasekhar limit (the maximum mass a white dwarf can attain) arises naturally due to the physics of electron degeneracy.

Explanation:

Degeneracy pressure keeps a white dwarf from collapsing under its own gravity.

What is Degeneracy pressure?

Electron degeneracy pressure is a particular manifestation of the more general phenomenon of quantum degeneracy pressure.

The maximum mass that a white dwarf can support against collapse is 1.4 solar masses due to the Chandrasekhar limit.

Habiba and selehadin have measured the voltage across a resistor to be 5.26V and the current flowing through in to be 0.41A they work out the resistance .

habiba says the resistance is 12.8 ohms .selehadin disagrees and says that is 13 ohm .

who is correct?.​

Answers

Considering the definitipn of current, voltage, power, and Ohm's law,

Current

The flow of electricity through an object, such as a wire, is known as current (I). Its unit of measurement is amps (A). So current is a measure of the speed at which the load passes through a given reference point in a specified direction.

Voltage

The conductive force (electrical pressure) behind the flow of a current is known as voltage and is measured in volts (V) (voltage can also be referred to as the potential difference or electromotive force). That is, voltage is a measure of the work required to move a charge from one point to another.

Resistance

Resistance (R) refers to the resistance or opposition that an element has to the passage of electric current. It is represented by the symbol Ω and indicates the resistance that an element offers to the passage of electricity.

This means that the greater the resistance to the passage of current, the lower the intensity or amount of electricity that passes through this conductor.

The resistance that is measured in ohms.

Ohm's law

Ohm's law indicates that the current through a circuit is directly proportional to its voltage or voltage and inversely proportional to the resistance it presents.

Mathematically, Watt's law is expressed:

[tex]I=\frac{V}{R}[/tex]

So if you want to find resistance, the expression for its calculation is:

[tex]R=\frac{V}{I}[/tex]

This case

In this case, you know:

V= 5.26 VI= 0.41 A

Replacing:

[tex]R=\frac{5.26 V}{0.41 A}[/tex]

Solving:

R= 12.8 ohms

Habiba is right. The resistance is 12.8 ohms.
