Answer:
pulling
Explanation:
When stretching, the right way to stretch is to stretch until one feels the tension pull in the muscle. This pull is then held and sustained for a period of about 15 to 60 seconds. This considered the safest way to stretch, and it gives the muscles and connective tissue time to “reset” the stretch reflex.
How balance of oxygen and carbon dioxide in the atmosphere is maintained?
Answer: The balance of oxygen and carbondioxide is made due to respreration and photosinthesis. As we leave carbon dioxide and take in oxygen the ballance of carbon dioxide and oxygen is made. And during the photosinthesis of plants the balance of carbon dioxide and oxygen is made.
how can energy and matter connected?
Answer:
Energy is a property that matter has. The same amount matter can have different amounts of energy and so represent different states of matter. For example, if you add energy to an ice cube made of water, it becomes liquid water, and if you add even more energy, it becomes steam.

Ganymede, one of Jupiter's moons, has a gravitational force of only 0.146 that of Earth. If a space probe with a mass of 126 kg on Earth lands on Ganymede, what would its mass be
Answer:
The mass of the space probe on Ganymede is 126 kg, and its weight is 180.2808 N.
Explanation:
The force of gravity, g, on the earth is 9.8 m/[tex]s^{2}[/tex].
The gravitational force on Ganymede = 0.146 × g
= 0.146 × 9.8
= 1.4308 m/[tex]s^{2}[/tex]
The gravitational force on Ganymede is 1.4308 m/[tex]s^{2}[/tex].
Mass of space probe on Earth is 126 kg.
Weight of the space probe on Earth = m × g
= 126 × 9.8
= 1234.8 kgm/[tex]s^{2}[/tex]
Weight of the space probe on Earth is 1234.8 N.
Since mass is constant, the mass of the space probe on Ganymede is 126 kg.
Weight of the space probe on Ganymede = m × g
= 126 × 1.4308
= 180.2808 kgm/[tex]s^{2}[/tex]
Weight of the space probe on Ganymede is 180.2808 N.
Answer:
126 kg
Explanation:
Mass is a constant for a body, and does not change with location.

in the lab you will use a cart and track to explore various aspects of motion you will measure and record the time it takes the cart to travel certain distances and then complete some calculations
Answer:
Hii! ^^
Explanation:
It is given that by using track and cart we can record the time and the distance travelled and also the speed of the cart can be recorded. With all this data we can solve questions on the laws of motion.
Like using the first law of motion we can determine the force of gravity acting on the cart that has moved a certain distance and the velocity or the speed of card has already been registered and since time is known putting the values in formula would help us calculate the gravitational pull acting on cart.
Happy To Help! ^^

A tennis ball moves 18 meters northward, then 22 meters
southward, then 14 meters northward, and finally 28 meters
southward.
What is the magnitude and direction of the displacement
Answer:
Magnitude = 18 m
Direction = southward
Explanation:
Given that a tennis ball moves 18 meters northward, then 22 meterssouthward, then 14 meters northward, and finally 28 meters
southward.
To calculate the displacement, let the
Northward = positive direction
Southward = negative direction
Displacement = 18 - 22 + 14 - 28
Displacement = 32 - 50
Displacement = - 18
Since the answer is negative,
The magnitude will be 18 m and direction of the displacement is southward

A cyclist moves a distance of 30 m from points A to B in a straught line towards East with a speed of 10 m/s. He then moves a distance of 40 m from points B to C in a straight line towards North with a speed of 20 m/s. Calculate the cyclist's (1) Average Speed, (2) Average Velocity, for the whole journey
Answer:
Average speed is 14 m/s and average velocity is 10 m/s.
Explanation:
The time consumed to travel from A to B = Distance / Speed = 30 / 10 = 3 seconds
The time consumed to travel from B to C = Distance / Speed = 40 / 20 = 2 seconds
Now, we find the average speed by using the below formula.
Average speed = total distance / total time
Average speed = (30 +40) / (3 + 2)
Avergae speed = 70 / 5 = 14 m/s.
Now find the average velocity.
Average velocity = displacement / time
Displacement, distance between A to C = [(30)^2 + (40)^2]^1/2 = 50 m
Average velocity = 50 / (3+2) = 10 m/s

A billion years ago, Earth and its moon were just 200000 kilometers apart. Express this distance in meters.
Answer:
The value is [tex]x = 200000000 \ m[/tex]
Explanation:
From the question we are told that
The distance between the earth and the moon is [tex]d = 200000 \ km[/tex]
Generally ,
[tex]1 \ km = 1000 \ m[/tex]
[tex]200000 \ km \to x \ m[/tex]
=> [tex]x = \frac{200000 * 1000}{1 }[/tex]
=> [tex]x = 200000000 \ m[/tex]
How long does it take an automobile traveling 66.7 km/h to become even with a car that is traveling in another lane at 52.7 km/h if the cars' front bumpers are initially 119 m apart?
Answer:
The time taken is [tex]t = 32.5 \ s[/tex]
Explanation:
From the question we are told that
The speed of first car is [tex]v_1 = 66.7 \ km/h = 18.3 \ m/s[/tex]
The speed of second car is [tex]v_2 = 52.7 \ km/h = 14.64 \ m/s[/tex]
The initial distance of separation is [tex]d = 119 \ m[/tex]
The distance covered by first car is mathematically represented as
[tex]d_t = d_i + d_f[/tex]
Here [tex]d_i[/tex] is the initial distance which is 0 m/s
and [tex]d_f[/tex] is the final distance covered which is evaluated as [tex]d_f = v_1 * t[/tex]
So
[tex]d_t = 0 \ m/s + (v_1 * t )[/tex]
[tex]d_t = 0 \ m/s + (18.3 * t )[/tex]
The distance covered by second car is mathematically represented as
[tex]d_t = d_i + d_f[/tex]
Here [tex]d_i[/tex] is the initial distance which is 119 m
and [tex]d_f[/tex] is the final distance covered which is evaluated as [tex]d_f = v_2* t[/tex]
[tex]d_t = 119 + 14.64 * t[/tex]
Given that the two car are now in the same position we have that
[tex]119 + 14.64 * t = 0 + (18.3 * t )[/tex]
[tex]t = 32.5 \ s[/tex]

A train goes 25000 m East in 1500 sec and then turns around and travels 29,000 m West for 1740 sec. Determine the distance, speed, displacement, and velocity.
Answer:
scalar d = 54000 m , v_average = 16,667 m / s
vector d = -4000 m , moved 4000 to the west
v_average = 0
Explanation:
his is a uniform motion exercise, but we must be careful with quantities that are scalars and vector quantities
The distance traveled is a scalar
d = d₁ + d₂
d = 25000 + 29000
d = 54000 m
the speed is a scalar, in the exercise it is not specified if the speed of each trajectory or the average speed. Therefore we will calculate the two
v₁ = d₁ / t₁
v₁ = 25000/1500
v₁ = 16,667 m / s
v₂ = 29000/1740
v₂ = 16,667 m / s
Since the two speeds are equal, the average speed is
v = (v1 + v2) / 2
v_average = 16,667 m / s
now let's calculate the displacement that is a vector, so it has direction in addition to modules
suppose the eastward direction is positive and the bold are vectors
d = d₁ - d₂
d = 25000 - 29000
d = -4000 m
this means that it moved 4000 to the west
velocity is a vector, we assume positive eastward movement
v₁ = 16,667 m / s
v₂ = - 16,667 m / s
v_average = (v1 -v2) / 2
v_average = 0

Can some please help me ? Thank you!
Answer:
Hey ! I think I can help with this question.
In the diagram you were given the speed which is 5.25m/s and you were also given distance which is 950metres.
So the formula which will be suitable in my own way will be speed=distance/time....Since you weren't given the time,then you can place the numbers in their respectively places which will be 5.25=950/time....Then you will cross multiply which will be 5.25t=950....Then 950÷5.25=180.952381 which is approximately 181. then don't forget to add your unit, time is measured in seconds so the answer is going to be 181seconds.This is what I know...I hope this helps you.....Thank you for the question

While John is traveling along a straight inter-
state highway, he notices that the mile marker
reads 257 km. John travels until he reaches
the 145 km marker and then retraces his path
to the 175 km marker.
What is John's resultant displacement from
the 257 km marker?
Answer in units of km.
Answer:
Explanation:
The first displacement when the mile reading changes from 257 to 145
= 257 - 145
= 112 km
Then he turns back . This time the displacement will be negative .
The mile reading changes from 145 to 175
displacement = - ( 175 - 145 )
= - 30 km
Final displacement = 112 - 30
= 82 km .
