The amoeba is having a asexual reproduction and the two birds are not. The two birds are having a sexual reproduction.
Answer:
It's displacement would be 25 km.
Explanation:
That is because you would subtract 10 from 35 to get the distance away from the starting point.
Density = mass ÷ volume
D= 44g ÷ 8 cm^3
D = 5,5 (round it) 6 g/cm^3
Answer:
Explanation:
In order to solve this problem we need to make a free body diagram of the book and the forces that interact on it. In the picture below you can see the free body diagram with these forces.
The person holding the book is compressing it with his hands, thus exerting a couple of forces of equal magnitude and opposite direction with value F.
Now the key to solving this problem is to analyze the equilibrium condition (Newton's third law) on the x & y axes.
To find the weight of the book we simply multiply the mass of the book by gravity.
W = m*g
W = 1.3[kg] * 9.81[m/s^2]
W = 12.75 [N]
