Balanced Forces =》 If the resultant of several forces acting on a body is zero, the forces are said to be Balanced Forces.

Or

When two forces of equal magnitudes but acting in opposite direction on an object simultaneously then the object continuous in its state of rest all uniform motion in a straight line such forces acting on the object are known as Balanced Forces.

Unbalance Forces =》 If the resultant of several forces acting on a body is not zero, the forces are said to be Unbalanced Forces.

Or

When two forces of unequal magnitudes act in opposite direction on an object simultaneously then object moves in the direction of the force with larger magnitude forces. These force acting on the object are known as Unbalanced Forces.

How does the height of a ramp affect the time it takes for an object to move down the ramp? please explain each one below:

weqwewe [10]

The greater the height of a ramp, the shorter the time it takes for an object to move down the ramp.

The greater the amount of salt, the In addition the larger the longer it takes water to boil.

An increase in volume of water increases the time it takes to boil and vice versa.

Increase in the length of the paper airplane, the farther it will fly.

Jumping Jack increases the heart rate.

<h3>How does the height of a ramp affect the time it takes for an object to move down the ramp?</h3>

A ramp is an inclined plane which is a form of simple machine that is used to lift heavy objects off the floor or to lower heavy objects down.

The greater the height of a ramp, the shorter the time it takes for an object to move down the ramp due to increased acceleration.

<h3>How does the amount of salt affect how long it takes water to boil?</h3>

The addition of solutes to pure solvent raises the boiling point of the solute.

Therefore, the greater the amount of salt, the In addition the larger the longer it takes water to boil.

<h3>How does the volume of water affect how long it will take to boil?</h3>

The mass of water increases with increase in volume of water.

Therefore, an increase in volume of water increases the time it takes to boil and vice versa.

<h3>How does the length of a paper airplane affect how far it will fly?</h3>

For a paper airplane the larger its wings, the greater the lift generated.

The greater the lift, the farther the paper airplane will fly.

Therefore, an increase in the length of the paper airplane, the farther it will fly.

<h3>How do jumping jacks affect your heart rate?</h3>

Exercise increases the heart rate.

Jumping jack is a for of exercise. Therefore, Jumping Jack increases the heart rate.

The titanium shell of an SR-71 airplane would expand when flying at a speed exceeding 3 times the speed of sound. If the skin of

Fed [463]

Answer:

The 10-meter long rod of an SR-71 airplane expands 0.02 meters (2 centimeters) when plane flies at 3 times the speed of sound.

Explanation:

From Physics we get that expansion of the rod portion is found by this formula:

$\Delta l = \alpha\cdot l_{o}\cdot (T_{f}-T_{o})$ (Eq. 1)

Where:

$\Delta l$ - Expansion of the rod portion, measured in meters.

$\alpha$ - Linear coefficient of expansion for titanium, measured in $\frac{1}{^{\circ}C}$ .

$l_{o}$ - Initial length of the rod portion, measured in meters.

$T_{o}$ - Initial temperature of the rod portion, measured in Celsius.

$T_{f}$ - Final temperature of the rod portion, measured in Celsius.

If we know that $\alpha = 5\times 10^{-6}\,\frac{1}{^{\circ}C}$ , $l_{o} = 10\,m$ , $T_{o} = 0\,^{\circ}C$ and $T_{f} = 400\,^{\circ}C$ , the expansion experimented by the rod portion is:

$\Delta l = \left(5\times 10^{-6}\,\frac{1}{^{\circ}C} \right)\cdot (10\,m)\cdot (400\,^{\circ}C-0\,^{\circ}C)$

$\Delta l = 0.02\,m$

The 10-meter long rod of an SR-71 airplane expands 0.02 meters (2 centimeters) when plane flies at 3 times the speed of sound.

The types of waves that transmit cell phone messages are most likely _____ . Choices: radio waves.. . gamma rays.. . ultraviolet

Anastaziya [24]

<span>Radio waves are the type of wave that most likely transmit cell phones messages. Radio waves can be used to transmit data and information at various frequencies. Gamma rays are high frequency and are dangerous to our health. Ultraviolet rays come from the sun. Infrared waves are ones we experience every day, even though it is invisible to the naked eye. This is the heat we feel from the sun. </span>
