Answer: 4.98 m/s
Explanation:
You solve these kinetic energy, potential energy problems by using the fact P.E.+ K.E. = a constant as long as friction is ignored.
PEi = 0 in this case
KEi = ½mVi² = PEf+KEf = mghf + ½mVf²
½1210*8.31² = 1210*9.8*2.26 + ½1210*Vf²
½1210*Vf² = ½1210*8.31² - 1210*9.8*2.26
Vf² = 8.31² - 2*9.8*2.26 = 4.98² so Vf = 4.98m/s
Explanation:
<h3>p = mv</h3>
- <em>p</em> denotes momentum
- <em>m</em> denotes mass
- <em>v</em> denotes velocity
→ p = 3 kg × 3 m/s
→ <u>p</u><u> </u><u>=</u><u> </u><u>9</u><u> </u><u>kg</u><u>.</u><u>m</u><u>/</u><u>s</u>
<u>Option</u><u> </u><u>D</u><u> </u><u>is</u><u> </u><u>corre</u><u>ct</u><u>.</u>
Traits are basically your phenotype. They include things like hair color, height, and eye color. Alleles are versions of genes. ... This is a pretty basic idea of how traits and alleles are related.
Answer:4.34 miles
Explanation:
first Elevation =
After 1 minute Elevation changes to 
Ditsance travelled in 1 minute =
=10 mile
Now
tan59=
H=xtan59
tan19=
H=
Equating H
we get
1.319x=10tan19
x=2.61 miles
H=
=4.34 miles
Answer:
from
force =mass x acceleration
mass = force/acceleration
m = f/a
m = 7.5/15
m=0.5kg
