Answer:
The amplitude is a measure of its change in a single period (such as time or spatial period)
what is amplitude?
Answer:A periodic variable's amplitude is a measure of its change across a single period, such as time or space. Amplitude is defined in a variety of ways, but they're all based on the size of the disparities between the variable's extreme values. The amplitude of a periodic function is sometimes referred to as the phase in older writings texts.

Adding salt
variable)
causes the boiling temperature of the water
variable) to increase.
When salt is added, it makes it harder for the water molecules to escape from the pot and enter the gas phase, which happens when water boils, Giddings said. This gives salt water a higher boiling point, she said.
Answer:
Explanation:
Adding salt (independent variable) causes the boiling temperature of the water (dependent variable) to increase.
albert jumps toward with an acceleration of 1.0 m/s^2 while he is in an elevator that is accelerating upwards of a rate of 1.5 m/s^2. what's alberts total acceleration
The Alberts' total acceleration will be +0.5 m/s².The total acceleration is the algebraic sum of all the acceleration.
What is acceleration?The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.
The total acceleration is the algebraic sum of all the acceleration.
When Albert is jumped toward the elevator the net acceleration is acting downward taken as a negative and the elevator is accelerating upwards the acceleration is taken as positive.
The total acceleration is found as;
[tex]\rm a_{net}= +1.5 m/s^2-1.0 \ m/s^2 \\\\ a_{net}=+0.5 \ m/s^2[/tex]
Hence, the Alberts' total acceleration will be +0.5 m/s².

What will be the ME of a machine that produces a 240 N work with a 300
N work input?
Given:
Solution:
Answer:
Answer:
Efficiency = 80%
Explanation:
Given the following data;
Work output = 240 N
Work Input = 300 N
To find the mechanical efficiency of a machine;
[tex] Efficiency = \frac {Out-put \; work}{In-put \; work} * 100 [/tex]
Substituting into the equation, we have;
[tex] Efficiency = \frac {240}{300} * 100 [/tex]
[tex] Efficiency = 0.8 * 100 [/tex]
Efficiency = 80%
Therefore, the mechanical efficiency of the machine is 80 percent.

An elevator car weighs 5500 N. If the car accelerates upwards at a rate of 4.0 m/s2, what is the tension in the support cable lifting the car? Use g = 10 m/s².
Answer:
Explanation:
The equation for this, since we are talking about weight on an elevator, is Newton's 2nd Law adjusted to fit our needs:
[tex]F_n=ma+w[/tex] where the Normal Force needed to lift that elevator car is the tension. So the equation then becomes
T = ma + w where T is the tension in the cable to lift the elevator, m is the mass of the elevator (which we have to solve for), a is the acceleration of the elevator (positive since it's going up), and w is the weight of the elevator (which we have as 5500 N). Solving first for mass:
w = mg and
5500 =- m(10) so
m = 550 kg. Now we have what we need to solve for the tension:
T = 550(4.0) + 5500 and
T = 2200 + 5500 so
T = 7700 N
Tension in the support cable which is lifting the car is 7700 N. The tension is a type of pulling force developed on a string or cable which is lifting the car.
What is Tension?
Tension is defined as the pulling force which is transmitted axially by the means of a string of an elevator. This tension is a result of action-reaction pair of forces which act at each end of the elements.
The weight on an elevator can be calculated by Newton's 2nd Law of motion:
w = mg
where, w = weight of the object,
m = mass of the object,
g = acceleration due to gravity
Here the Normal Force is needed to lift that elevator car is the tension. So, the tension can be calculated by the equation as follows:
T = ma + w
where, T = tension in the cable to lift the elevator,
m = mass of the elevator,
a = acceleration of the elevator,
w = weight of the elevator
By substituting the values in this equation:
w = mg
5500 = m(10)
m = 550 kg
The tension in the support is
T = 550(4.0) + 5500
T = (2200 + 5500)
T = 7700 N
Therefore, the value of tension on the cable is 7700 N.

with a wavelength of 2.5 x 102 m.
Calculate the frequency of the radio waves.
Answer:
1.2×10⁶ Hz
Explanation:
Applying,
v = λf............. Equation 1
Where v = speed of wave, λ = wavelength, f = frequency.
make f the subject of the equation
f = v/λ............... Equation 2
From the question,
Given: v = 3.0×10⁸ m/s, λ = 2.5×10² m
Substitute these values into equation 2
f = 3.0×10⁸/2.5×10²

The image shown is an illustration of Kepler’s second law. An illustration with a circle representing the sun and a smaller circle representing a planet. The sun is at a focus of a draw ellipse that the planet is on. There are lines drawn radially out from the Sun to the elliptical path of the planet. The planet is at the part of the ellipse that is closest to the sun. The position of the planet is labeled W and the position opposite the planet is labeled Z. The line closest to W is labeled X and the line closest to Z is labeld Y. Which conclusion is best supported by the image? The gravitational force at W is less than the gravitational force at Y. The time needed to travel from W to X is the same as the time needed to travel from Y to Z. The gravitational force at W is the same as the gravitational force at Y. The time needed to travel from W to X is greater than the time needed to travel from Y to Z.
Answer:
B; the time needed to travel from W to X is the same as the time needed to travel from Y to Z.

Please answer ASAP
We know that,
p = mv
Where p is momentum,m is mass & v is velocity.From ques. we have;
mass = 50 kgVelocity = 8 m/sSo,
p = 50 × 8
p = 400 kg m/s
p = mv
Clearly, now just put the values
