Dogs dream like humans and about similar things. Many people believe that dogs do dream. Most dog owners have noticed that at various times during their sleep, some dogs may quiver, make leg twitches, or may even growl or snap at some sleep-created phantom, giving the impression that they are dreaming about something.
Explanation:
mass of earth (m1)=5.97×10^24
mass of moon (m2)=7.35×10^22
distance between their center (d)= 3.84×10^8
G=6.67×10^-11
now,
gravitational force =(F)= G(m1×m2)/d²
- 6.67×10^-11(5.97×10^24×7.35×10^22)/(3.84×10^8)
- 19.84×10^19

Answer:
Impulse = 80Ns
Explanation:
Given the following data;
Mass = 3kg
Force = 20N
Time = 4 seconds
To find the impulse experienced by the object;
Impulse = force * time
Impulse = 20*4
Impulse = 80Ns
Therefore, the impulse experienced by the object is 80 Newton-seconds.
