Calcium is the #1 material needed for bone development
Answer:
a = 10 m/s²
F = 2000 N
m = 8.57 Kg
Explanation:
1) What is the acceleration of a 40 kg object pushed with a force of 400 N?
Acceleration of object = ?
Mass of object = 40 Kg
Force on object = 400 N
Solution:
Formula:
F = ma
by putting values,
400 N = 40 Kg × a
a = 400 N/ 40 Kg ( N = Kg.m /s²)
a = 10 m/s²
2) What is the force on an 800 kg rock being thrown at 2.5 m/s2?
Acceleration of object = 2.5 m/s²
Mass of object = 800 Kg
Force on object = ?
Solution:
Formula:
F = ma
by putting values,
F = 800 Kg × 2.5 m/s²
F = 2000 Kg. m/s² ( N = Kg.m /s²)
F = 2000 N
3) What is the mass of a ball being rolled at 3.5 m/s2 from a 30 N force?
Acceleration of object = 3.5 m/s²
Mass of object = ?
Force on object = 30 N
Solution:
Formula:
F = ma
by putting values,
30 N = m × 3.5 m/s²
m = 30 N / 3.5 m/s² ( N = Kg.m /s²)
m = 8.57 Kg
What this student is doing is collecting data. So, he wants to check how many life forms there are in the waters nearby. In order to do so, he has to take a sample, and look at it through a microscope so as to determine the number. So, he collected a sample which is his data. He is not drawing conclusions yet, but rather counting these organisms. He is not making a peer review - his peers aren't even mentioned here. He is not forming a hypothesis because he is just counting at this point.
Answer:
R (capital letter) is the dominant allele so the phenotype is the same
