Answer:
Self- Actualization
Explanation:
Understanding your talents and what you can do.
Answer:
13.4 m/s
Explanation:
Write down what you have, so:
V0=8 m/s
a=2.7 m/s^2
t=2 seconds
We are trying to find final velocity, so we will use vf = v0 + at
From there, we plug in the given values.
vf = 8 m/s + (2.7 m/s^2 x 2 seconds)
vf = 13.4 m/s
The centripetal force : F = 293.3125 N

</h3>
Given
mass = 65 kg
v = 9.5 m/s
r = 20 m
Required
the centripetal force
Solution
Centripetal force is a force acting on objects that move in a circle in the direction toward the center of the circle
F = centripetal force, N
m = mass, Kg
v = linear velocity, m / s
r = radius, m
Input the value :
F = 65 x 9.5² / 20
F = 293.3125 N
Answer:
3859 g
Explanation:
1 pound = 0.454 kg
therefore, 8.50 ponds = 0.454*8.50 = 3.859
to covert kilograms into grams you need to multiply it by 1000
=3.859*1000
= 3859 grams
Answer:
2×10⁻⁷ Ωm
Explanation:
From the question,
R = 4ρL/πd².................... Equation 1
Where R = Resistance of the wire, ρ = resistivity of the wire, L = length of the wire, d = diameter of the wire.
Therefore,
ρ = Rπd²/4L............. Equation 2
Given: R = 1 ohm, ρ = 1×10⁻⁷Ωm
1×10⁻⁷ = πd²/4L.................... Equation 3
If the length and the diameter are doubled, and the resistance remaining constant
ρ' = π(2d)²/4(2L)
Where ρ' = new resistivity
ρ' = 4πd²/8L
ρ' = 2πd²/4L = 2ρ
ρ' = 2(1×10⁻⁷)
ρ' = 2×10⁻⁷ Ωm
