Answer:
To go from 20.0 to 30.0 m/s, that is a velocity change of 10.0 m/s.
From the definition of acceleration,
a = (velocity change)/(time required)
In this case you know that a = 5.0 m/s^2, so
time = (10.0 m/s)/(5.0 m/s^2)
= 2.0 seconds
Answer:
The force is inversely proportional to the square of radial distance and the mass of the lemon is compensated.
Explanation:
- It is true that our body is composed mostly of water (precisely 75% of the body mass) which is influenced by the gravitational forces. This gravitational force in the water bodies cause tides.
We know that mathematically gravitational force is given as:
where:
R = radial distance between the masses
we observe that:
The force is inversely proportional to the square of radial distance.
- And the radial distance between the moon and a human on the earth is much greater than the distance between a lemon of low mass on the head of a human.
Answer: Chloroplast
Explanation: Chloroplasts work to convert the Sun's light energy into sugars that cells can use. It's like a solar panel that converts energy from sunlight into electric power.
