Answer:
height=2
Explanation:
MA= input/output
MA= 5
input = 10 (the ramp)
output=x (the height)
5=10/x
x=2
B) because the air pressure is significantly higher when it is colder
C) because the molecules in the balloon have slowed down with the temperature
D) because the molecules shrink in size when exposed to the colder, outside air
Answer: Option (C) is the correct answer.
Explanation:
When the balloon was placed inside Tamika's classroom then the temperature was high as compared to the temperature outside the classroom.
As a result, gas molecules were in rapid motion but when balloon was placed outside the classroom then due to cold, there was decrease in temperature.
Therefore, the movement of gas molecules will slow down and the molecules will come slightly close to each other.
Hence, there will be shrinkage in the size of balloon.
Thus, we can conclude that the balloon has gotten a little bit smaller because the molecules in the balloon have slowed down with the temperature.
The speed of an object is the distance divided by the time of travel. The speed of the person running 400 meters in 2 minutes is 3.3 m/s.
Speed is a physical quantity used to measure the distance covered per unit time. Speed is a scalar quantity thus, having magnitude only. The rate of speed is called velocity. Velocity is a vector quantity.
Speed in physics is the ratio of the distance covered per unit time. Thus, speed can have the units m/s, Km/hr, ft/s miles/s etc. As the time of the travel increases, speed is said to be decreasing.
The distance covered = 400 meters.
time = 2 minutes = 2 × 60 s = 120 s
Speed = distance / time
= 400 m/ 120 s
= 3.3 m/s.
Therefore, the speed is 3.3 m/s.

Answer:
3.3m/s
Explanation:
speed =Distance /Time
x=400m
t=2mintues=2min*60sec/min=120seconds
S=400m/120s
S=3.33333...
therefore speed = 3.3m/s
b. inertia
c. average force
d. force of gravity
all planets look as though they lie along a flattened circular plane or disk
the Sun and planets rotate in the same direction
all moons orbit planets in a counterclockwise direction
Our solar system is made up of an ordinary star known as the Sun. All moons orbit planets in a counterclockwise direction are not one of the observed characteristics of our solarsystem.
Our solar system is made up of an ordinary star known as the sun, as well as the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
It contains the planets' satellites, as well as countless comets, asteroids, and meteoroids, as well as the interplanetarymedium.
When viewed from the Northpole or the North star Polaris, the Moon and all other typical non-asteroid size moons in our solar system orbit their host planet in a counter-clockwise manner.
