The potential energy of the egg when it begins to fall is equal to the kinetic energy of the egg just before touching the ground:
m * g * h = (1/2) * m * v ^ 2
Clearing the speed:
v = root (2 * h * g)
Substituting the values
v = root (2 * (10) * (9.8)) = 14
Then, by definition, we have
F * deltat = m * deltav
Clearing F
F = (m * deltav) / (deltat)
Substituting the values
F = ((0.060) * (14)) / (2) = 0.42
answer
the force exerted on the egg by the floor was 0.42N
Between 12 to 16 weeks, depending on water and food supply, the frog has completed the full growth cycle. So the male frogs grow old at the age(s) of 2-3 years old for breeding.
Answer:
one of the characteristics of a mammal is their several hollow bones another is their three chambered heart and the last is highly developed nervous system
Explanation:
the reason i picked those three is because not all mammals live their life on land and also mammals font have internal fertillization when they are done they take care of their babies and when they grow up they live their own life
Answer:
A
Explanation:
In 5 minutes, they went 10 miles at both 2, 3, and 4 checkpoints. The bus then starts to speed up.
Hope this helps!
