Answer:
Explanation:
velocity of vehicle u = 20 m/s
acceleration a = 22 m /s²
distance s = 170 m
time t = ?
s = ut + 1/2 a t²
170 = 20 t + 1/2 x 22 t²
170 = 20t + 11 t²
11 t² + 20 t - 170 = 0
t = 3 s
Answer:
One atom will give electrons to another atom to fill its shell, this is an ionic bond. The atom giving away electrons becomes positive and the one recieving electrons becomes negative.

Answer:
b. the planets are marble-size or smaller and the nearest stars are thousands of miles away
Explanation:
The correct answer for the question is option b because if the distance between sun and Pluto is any scale is made equivalent to a walking distance of some minutes then the size of planets will be equivalent to the size of marbles and the nearest stars that is present in Alpha centauri triple star system(4.5 light years away) will be approximately thousands of miles away from us.
