Answer:
0.5 m/s²
Explanation:
Applying,
F = ma............... Equation 1
Where F = Force applied to the chair, m = mass of the student, a = acceleration of the chair
make a the subject of the equation
a = F/m............ Equation 2
From the question,
Given: F = 35 N, m = 70 kg
Substitute these values into equation 2
a = 35/70
a = 0.5 m/s²
Hence the new acceleration of the chair is 0.5 m/s²
Answer:
200 K
Explanation:
0 °C = 273 K
-73°C = 273 K - 73 K = 200 K
Answer:
36 minutes
Explanation:
Distance= Time*Speed
Let time taken to go to city be x hours, therefore, time to travel back is (2-x) hours
The distance to and from the city are equal hence
15x=35(2-x)
15x=70-35x
50x=70 hence x=70/50=1.4 hours
Time to drive home will be 2-x=2-1.4=0.6 hours
0.6*60=36 minutes
Therefore, time to travel back home is 36 minutes
Scientist identify the process in which gravity pulled materials together forming the planets in our solar system as accretion.
Accretion is the formation model of planets in our solar system in which gravity pulls materials together forming the planets.
This formation model accounts for the formation of the inner planets made of of dense material such as iron. These planets include Mercury, venus, earth etc.
As the gravity pulls in the more dense material, the less dense material such as ice, liquid and gas colect together to form the outer planets, which include Jupiter, Uranus, etc.
So, Scientist identify the process in which gravity pulled materials together forming the planets in our solar system as accretion.
