Since the piston is forced to slide in a straight path, it experiences rectilinear translation. Given that it will remain horizontal while traveling in a circular motion, the connecting rod goes through curvilinear translation.
What type of motion does the piston make?The piston reciprocates up and down in a straight line as the crank turns. Rotational motion into linear motion is converted via a crank and piston arrangement. According to the guide's orientation, the linear motion can be either vertical or horizontal (or in another direction).
How are rectilinear and curvilinear defined?Rectilinear motion is a motion in a straight line. In this motion, each particle travels the same distance in a straight line in a parallel fashion. Curvilinear Motion: The motion of a curved line.

the distance from earth to the sun is used to measure distances in the solar system and is called a light year. group of answer choices true false
The given statement is flase. The distance from earth to the sun is used to measure distances in the solar system and is not called a light year,but an astronomical unit.
How is distance measured in solar system?When represented in miles and kilometers, the distances between the planets, and especially between the stars, can grow to be cumbersome. We thus transition to whole different sorts of units for cosmic distances, such as astronomical units, light years, and parsecs.
The average distance between Earth and the Sun, or 93 million miles or 8.5 light-minutes, is measured in astronomical units (AU). A light-year is the approximate 6-trillion-mile distance that light travels in a year in a vacuum. Approximately 64,500 times longer than an AU is a light-year.
The Light Year is perfect for determining distances to faraway galaxies or stars, but it is ineffective when determining distances inside our solar system. A light may travel around 10 trillion kilometers, or 106 Km, in a single year.

if my mass on earth is 70 kg, calculate my mass on the moon where the acceleration due to gravity (g) is 1.6 m/s^2. explain your answer.
My mass on the moon would be 44 kg.
This is because mass is a measure of an object's inertia, which is determined by its density and volume. Since the acceleration due to gravity on the moon is 1.6 m/s^2, the force of gravity acting on the object will be less than it is on earth, and therefore the object's mass will be less. To calculate the mass on the moon, we can use the equation m = mg/g, where m is the mass on the moon, m is the mass on earth, and g is the acceleration due to gravity. In this equation, the mass on earth is 70 kg and the acceleration due to gravity on the moon is 1.6 m/s^2, so the mass on the moon would be 70 kg x 1.6 m/s^2/9.8 m/s^2 = 44 kg.
Step 1: Determine the formula to calculate your mass on the moon. The formula to calculate mass on the moon is mass on the moon = mass on earth * (acceleration due to gravity of the moon/acceleration due to gravity of the earth).
Step 2: Insert the values into the formula. Mass on the moon = 70 kg * (1.6 m/s^2 / 9.8 m/s^2)
Step 3: Solve the equation. Mass on the moon = 70 kg * (0.1633) = 11.431 kg
Therefore, your mass on the moon is 11.431 kg.

From what maximum height could a person jump and land rigidly upright on both feet without breaking his legs? assume that all the energy is absorbed in the leg bones in a rigid landing. Neglect any friction.
The maximum height is 4.33m from which a person can jump rigidly without breaking any bones.
We have some data like bone maximum bearable energy is 3000J.Also,mass of person is 70kg.We know that a person cannot be broken until person jump from that height where the potential energy of person due to its position is greater than the bone energy.
It means that we need to equate or potential of person with the bone energy.
We know that potential energy of person is given by =mgh where m is the mass of the body, g is acceleration due to gravity and h is the height of the body.
Therefore, potential energy is =m × g × h
=>potential energy=70×9.8×h---------(eq1)
Now, we have bone energy =3000J -----(eq2)
Equate both equations,we get
=>70×9.8×h=3000
=>h=(3000/(70×9.8)

if the source is stationary, how will the received signal change if the observer is moving towards the source?
The measured frequency rises as the observation gets closer to the static source, exceeding the source rate. The frequency difference between the perceived and source frequencies occurs when an observation is moving further away from a stationary source.
When measuring noise out of a source, the spectator's movement may modify the frequency: A greater frequency is measured by an observation who is traveling to the source. Reduced frequency is measured by an observer who is progressing away from the source. A stationary wavelength is not affected while a source is travelling in its direction.
The observer's velocity will be zero as the source arrives; as both a result, variations in frequency and wavelength will occur. Due to their inverse relationship, when wavelength is increased, frequency drops and conversely. Inquiry shows that 1=[VV5V+O]. Contains a detailed prevalence has nevertheless grown.

the total mass of the sun is about 2x1030 kg of which 75% was hydrogen when the sun formed. however, only about 13% of this hydrogen ever becomes available for fusion in the core. the rest remains in the layers of the sun where the temperature is too low for fusion. c) based on the given information, calculate the total mass of hydrogen available for fusion over the lifetime of the sun.
The total mass of hydrogen accessible for fusion over the sun's lifespan is roughly 1.95x10^28 kg.
What exactly is hydrogen?
Hydrogen is the lightest and most abundant element in the universe. The chemical element H has the atomic number 1 and is represented by the letter H. It is a highly combustible gas that has no flavour, odour, or colour and may be used as fuel. Hydrogen, which is created from a number of feedstocks such as natural gas, coal, and biomass, is commonly utilised as a clean energy source since it only emits water when burned.
According to the issue:
Using the available data, the total amount of hydrogen in the sun must be computed in order to identify the percentage of this mass that is appropriate for fusion in the core.
The entire mass of the sun is stated as 2x10^30 kg, with hydrogen accounting for 75% of this mass when the sun originated. This suggests that the total amount of hydrogen in the sun is (2x10^30 kg) x (75%).
The proportion of this mass accessible for fusion in the core is stated to be 13%. This suggests that the total amount of hydrogen accessible for fusion in the core is 1.95x10^28 kg (1.5x1030 kg) x (13%).
As a result, the total mass of hydrogen accessible for fusion during the sun's lifespan is roughly 1.95x10^28 kg.

t = - 7/ a--- (2)
From the kinematics the displacement is given by the equation:
S= ut +1/2 at ²
Now, put the values of u, S, and t in the above equation.
10 = 7*-7/a +1/2 *a*49/a²
Now, simplify the above equation.
20a = -49
a = -2.45
So, the magnitude of the car's acceleration is 2.45 m/.
