Answer:
254
Explanation:
use the formula "final Velocity- initial velocity / time = acceleration"
so "X - 14 /4 = 60"
60 x 4 = X - 14
240 +14 = X
X = 254
Answer:
7.745 feet
Explanation:
Data provided:
Length of the pole, L = 6 feet
Distance between the stake from the bottom of the pole, B = 4 feet
let the length of the rope be 'x'
Now,
The top of the pole, the bottom of the pole and the stake forms a right angled triangle.
Thus,
Using the concept of Pythagoras theorem,
we have
length of the pole as perpendicular, Distance between the stake from the bottom of the pole as base and length of the rope as hypotenuse
therefore,
L² + B² = x²
on substituting the values, we get
6² + 4² = x²
or
x = √60
or
x = 7.745 feet
You haven't told us what the passing percentage is on the exam,
or what the passing percentage is for the semester, or any of that.
Explanation:
u=40
v=?
h=?
v²-u²=2gs
0²-40²=2×10×s
160=20s
s=160/20
=80m/s
total distance= upward distance ×downward distance
=80+80
=160m
total displacement=0 because u and v is the same.
Answer:
The Nucleus
Explanation:
The nucleus contains the majority of an atom's mass because protons and neutrons are much heavier than electrons, whereas electrons occupy almost all of an atom's volume. I hope this helps you :D
