In Newton’s second law, if the net force acting on object doubles. The object’s Will also double
Answer: Explanation:
If the net force on an object is doubled, its acceleration will double If the mass of an object is doubled, the acceleration will be halved .
In Newton’s second law, if the net force acting on object doubles then either acceleration is double or mass is double.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
According to Newtons second law force is product of mass and acceleration.
F = ma
In Newton’s second law, if the net force acting on object doubles then either acceleration is double or mass is double.

What are the relationships between the different wave properties (frequency, wavelength, wave speed, period, amplitude)
Ex) As ___ increases, ___ increases/decreases/remains the same.
Answer:
As frequency (cycles per second) increases the wavelength decreases.
As frequency increases the period also decreases
If wave speed or velocity increases, so too does the frequency
Amplitude of a wave is totally independent of frequency, period etc. So it remains the same as frequency shifts. Like FM radio the amplitude remains the same as the frequency of the broadcast modulates.
Explanation:
F= 1/t Frequency is inversely proportional to time (wavelength)
Period is the time it takes for one wave cycle to complete Period is 1/f
++++++++++++++++++++++++++++++++++++
vw=λT Speed of propagation vw= wavelength x T time
vw=fλ Knowing frequency multiply times wavelength to get wave speed.
++++++++++++++++++++++++++++++++
Amplitude varies only as the energy applied varies. Like transmission power, in a 60 hz power feed the amplitude can be 120, 230, 460 volts (note these nominal amplitudes are RMS root mean squared or .707 of the peak of the waveform).

An object launched at 65 degrees from the horizontal would have the same range
(distance travelled) as an object launched from? Write only the WHOLE number with
no units (example: 65)
Answer:
An object launched from 65° will have the same range as an object launched from 25°
Explanation:
The formula for the horizontal range, R, is given as follows;
[tex]R = \dfrac{v \times sin(2\cdot \theta)}{g}[/tex]
Therefore, given that sinθ increases from 0 to 1 for θ values from 0 to 90° and decreases from 1 to 0 for θ values from 90° to 180°, and that the values of sin(θ) are positive in the first and second quadrant, we have that for the given angle, θ = 65°, the range is therefore;
[tex]R = \dfrac{v \times sin(2\times 65 ^{\circ})}{g} = \dfrac{v \times sin(130 ^{\circ})}{g}[/tex]
The location of 130° = Second quadrant
A rotation of 130° in the counterclockwise is equivalent to a rotation of 50° in the clockwise direction
Therefore, we have sin(130°) = sin(50°)
Therefore, the range for 130°/2 = 65° is the same as the range for 50°/2 = 25° and an object launched from 65° will have the same range as an object launched from 25°.

sports car accelerates from rest to 26.8 m/s (roughly 60 mi/h) in 5.1 seconds. What is the acceleration of the car?
One minute after takeoff, a rocket carrying the space shuttle into outer space reaches a speed of 447 m/s. What was the average acceleration of the rocket during that initial minute?
Answer:
5.3m/[tex]s^{2}[/tex]; 7.45m/[tex]s^{2}[/tex]
Explanation:
the magnitude of a=(change in speed)/(the time took to accelerate to the speed above)
So for that sports car, a=(26.8m/s-0m/s)/(5.1s)=5.2549m/[tex]s^{2}[/tex], knowing from the question that the sig fig of this question depend on "5.1 seconds", so the answer should be 5.3 m/[tex]s^{2}[/tex]
For the rocket, a=(447m/s-0m/s)/(1 minute)=(447m/s)/(60s)=7.45m/[tex]s^{2}[/tex]

For a substance to change from a liquid to a solid, what must happen to its
particles?
O A. They must lose enough of their kinetic energy that their movement
is influenced by the attractions between them.
B. They must gain enough kinetic energy to allow them to move
freely while still being attracted to one another.
C. They must lose enough of their kinetic energy so that the
attractions between them hold in place as they vibrate.
D. They must gain enough kinetic energy to break out of their rigid
structure and move independently.
Answer:
C. They must lose enough of their kinetic energy so that the attractions between them hold in place as they vibrate.
Explanation:
The "kinetic energy" refers to the energy of an object when it is moving. This is directly proportional to the object's "thermal energy." If the kinetic energy of an object increases, the thermal energy increases and if the kinetic energy decreases, the object's thermal energy decreases as well.
Changing the phase of an object from liquid to solid means that the object will be subjected to low temperature. This means the thermal energy will decrease as well as the kinetic energy. This is known as "freezing." The object needs to lose enough kinetic energy. This results to its particles moving closer together in an attractive force.
So, this explains the answer.

ice floats in water. which must be true. A. Ice molecules have more mass than water molecules. B. Ice molecules have less mass than water molecules. C. A volume of ice has less mass than the same volume of water. D. one gram of ice has less volume than 1 g of water.
Answer:
B
Explanation:
As we all know,mass is the amount of substance a body contains. So because Ice's mass is less than water, that's why it's able to float. In other words,we say ice is less dense than water
A volume of ice has less mass than the same volume of water. Hence, ice floats in water. Option (C) is correct.
What is density?The density of a material indicates the density of that material in a specific area. The density of a material is defined as its mass per unit volume. Density is a measurement of how closely matter is packed together. It is a distinct physical property of a specific object.
Archimedes, a Greek scientist, discovered the density principle. If you know the formula and understand the units, calculating density is simple. Density is represented by the symbol ρ, which can also be represented by the letter D.
Now, ice has less density compare to water. So, a certain volume of ice has less mass than the same volume of water. Hence, option(C) is correct.

A ping pong ball rolls off a 5.Om high table and lands on the floor, 3.0m
away from the table. How long is the ball in the air?
Answer:
The ball was 1.01 seconds in the air
Explanation:
Horizontal Motion
When an object is thrown horizontally with a speed v from a height h, the range or maximum horizontal distance traveled by the object can be calculated as follows:
[tex]\displaystyle d=v\cdot\sqrt{\frac {2h}{g}}[/tex]
If we know the value of d and h, we can solve the equation for v:
[tex]\displaystyle v=d\cdot\sqrt{\frac {g}{2h}}[/tex]
Since the horizontal speed is constant, we can calculate the time the ball was in the air by using the equation:
[tex]\displaystyle t=\frac{d}{v}[/tex]
The ping pong ball rolls from a height of h=5 m and lands on the floor a distance of d= 3 m away from the table. Calculate the speed:
[tex]\displaystyle v=3\cdot\sqrt{\frac {9.8}{2\cdot 5}}[/tex]
[tex]\displaystyle v=3\cdot\sqrt{\frac {9.8}{10}}[/tex]
Calculating:
[tex]v=2.97\ m/s[/tex]
Now calculate the time:
[tex]\displaystyle t=\frac{3}{2.97}[/tex]
[tex]t=1.01\ sec[/tex]
The ball was 1.01 seconds in the air
Note: The time does not depend on the distance d at all. If we borrow the equation from free-fall motion, the time can be calculated with:
[tex]\displaystyle t=\sqrt{\frac {2h}{g}}=\sqrt{\frac {10}{9.8}}=1.01\ sec[/tex]
