Speed = distance / time
= 125 miles / 2 hr
= 62.5 mi/h
Convert 65.5 mi/h to km/h
= 65.5 / 5
= 13.1
=13.1 x 8
= 104.8 km/h
Therefore speed equal 104.8 km/h
The energy that will be released will be 8.95×10^(21) Joules
for comparison, the Nagasaki atom bomb released 8.8*10^(13) Joules
so this meteorite is (8.95×10^(21))/(8.8*10^(13))=100×10^6 (100 million) times more destructive
Answer:
correct option is d) 7.0 x 10^-7 N
Explanation:
given data
distance = 175 picometers = 1.75 × m
to find out
electrical force
solution
we know atomic no of uranium is 92
and charge on electron is = 1.6 × C
and electrical force is express as
electrical force = .............1
put here value we get
electrical force =
electrical force = 6.921 × N
so correct option is d) 7.0 x 10^-7 N
Answer:
Distance, S = 110 meters
Explanation:
Given the following data;
Initial velocity = 15 m/s
Acceleration = 4 m/s²
Time = 5 seconds
To find the distance covered, we would use the second equation of motion;
Where;
S is the distance covered or displacement of an object.
u is the initial velocity.
a is the acceleration.
t is the time.
Substituting the values into the equation, we have;
Distance, S = 110 meters
