Explanation:
1500 m (100cm/m) / 3 cm/yr = 50 000 yrs.
I believe these are the answers
#1- D
#3-B
#4- D
#5- D
#6-A
#7-B
I was able to get everything except #3
I hope this helps though :)
Explanation:
according to Mendel's law taking the color as an example for pea plants.
here the trait for green seed is dominant (G) and the trait for yellow seed (g) are recessive. cross of (G)(G) in generation F1 in order to produce maximum number of off-spring with green seed. look below in the picture
Answer:
true if it is less dense than the liquid its in it will float
Explanation:
Answer:
Assuming air resistance is negligible, all of the potential energy that the object has at the top of the ramp is converted into kinetic energy by the time it gets to the bottom of the ramp. This is because no matter what path the object takes to move the 5m vertically (ie. falling straight down v. sliding on the ramp), gravity does the same amount of work on it.
Thus, calculate the total amount of potential energy at the top of the ramp:
Ep=mgh
Ep=4(9.81)5
Ep=196.2 Joules
Because all of this potential energy is converted into kinetic energy in the object by the bottom of the ramp, the object hits the spring with 196.2J of energy.
By using the formula for elastic potential energy, you can calculate exactly how far the spring compresses.
196.2=(1/2)k(x^2)
392.4=(350)(x^2)
1.1211=x^2
sqrt(1.1211)=x
x=1.059m
As for the last part of the question, after the object compresses the spring fully and stops momentarily, the spring converts it's elastic potential energy back into kinetic energy in the object and pushes it away again.
