Answer:
The new speed of the ball is 176.43 m/s
Explanation:
Given;
mass of the ball, m = 7 kg
initial speed of the ball, u = 5 m/s
applied force, F = 300 N
time of force action on the ball, t = 4 s
Apply Newton's second law of motion;
where;
v is new speed of the ball
Therefore, the new speed of the ball is 176.43 m/s
Answer:
false
Explanation:
As both parents contribute half of the new organism's genetic material, the offspring will have traits of both parents, but will not be exactly like either parent
The crust is less dense than the core because the crust isn't under pressure like the core is.
Explanation:
the formula is given by :
F=<u>Gm'•m"/</u> r²
where F is the force pulling them towards each other
G is the universal gravitational constant
m'andm" are the masses in contact
and r is the separation between the balls
so we just need to substitute the values and find r ,the gravitational constant is 6.67x10-¹¹. r=Gm'm"/F
