Answer:
Explanation:
Given data
Change in velocity Δv=14 m/s
Acceleration a=1000 m/s²
Required
Time t
Solution
We know that the acceleration is given by the velocity change over time interval.Therefore
a=Δv/t
Substitute the given values to find time t
So
Answer:
The presence of dwarf galaxies around the Milky Way supports what picture that our galaxy was formed by a coming together or combination of smaller systems
Momentums equation is just p=mv
mass times velocity so 50x200
p=10,000
Answer:
B. 4a
Explanation:
Force between the charges is inversely proportional to the square of the distance
=> Force will be 4 times and acceleration will be 4a
=> Answer b).
