B) initial speed (u)=3
final speed (v)=8
time (t)= 10
acceleration (a)=?
v=u+at
8=3+a(10)
5=10a
a=1/2= 0.5 m/s²
c)displacement (s)=?
1st section of journey
v ²=u ²+2as
8 ²=3 ²+2(0.5)s
64=9+1s
s=55meters
2nd section of journey
a=0
t=7
u=8
s=?
s=ut+1/2at²
s=8(7)+1/2(0)(7 ²)
s=56 meters
56+55= 111 meters
(For graph x axis =time (sec) & y axis= velocity (m/s))
The universe is made up of baryonic matter which is a combination of protons, electrons, and neutrons, and also dark matter and dark energy.
Galaxies are comprised of stars, while the universe is comprised of galaxies.
I hope my answer has come to your help. God bless and have a nice day ahead!
The correct option is this: THIS IS THE DEMONSTRATION OF BOYLE'S LAW. AS THE VOLUME INCREASES, THE PRESSURE DECREASES AND THE MARSHMALLOW WILL GROW LARGER.
Boyle's law states that the volume of a gas is inversely proportional to the pressure of the gas at constant temperature. The law explains the relationship between the volume and pressure of a gas at constant temperature.
Answer:something empty depressed
Explanation:
Answer:
A theory changes based on new observations and testing.
Explanation:
A scientific theory is a product of multiple trials and repeated experiments. It usually follows after carefully conducting and testing the validity of the hypothesis.
A scientific theory provides an explanation into how something behaves.
A law just states a finding will not explain it.
Most theories are tenable and can be improved upon when new observations and testing are carried out.
