To solve this problem it is necessary to apply the concepts related to the Force from Hook's law as well as the definition of the period provided by the same definition.
We know that the Force can be defined as
Where
k = Spring constant
x = Displacement
g = Gravity
m = mass
At the same time the period of a spring mass system is defined as
Where
m = Mass
k = Spring constant
Our values are given as,
m = 0.404kg
x = 0.666m
Replacing to find the value of the Spring constant we have that
Now using the formula of the period we know that
Finally, if the oscillation was 0.359m
The maximum height will be determined by the total length of that oscillation being equivalent to
I mean it’s alaska so i’m assuming B but i could be very wrong
Answer: total mechanical energy of -4.6 x 10^10 j.
Explanation: the planet express is in a circular orbit around the earth and has a total mechanical energy of -4.6 x 10^10 j.
The total mechanical energy is the sum of potential energy and the kinetic energy.
For the rocket to experience the escape from earth, the total work done will be equal to maximum kinetic energy.
According to conservative of energy, maximum kinetic energy is equal to the total mechanical energy.
The work must be provided by the planet expresss rockets in order to completley escape earth will be equal to total mechanical energy of -4.6 x 10^10 j.
Answer:
L = 169.5 m
Explanation:
Using Ohm's Law:
V = IR
where,
V = Voltage = 1.5 V
I = Current = 10 mA = 0.01 A
R = Resistance = ?
Therefore,
1.5 V = (0.01 A)R
R = 150 Ω
But the resistance of a wire is given by the following formula:
where,
ρ = resistivity = 1 x 10⁻⁶ Ω.m
L = length of wire = ?
A = cross-sectional area of wire = πr² = π(0.6 mm)² = π(0.6 x 10⁻³ m)²
A = 1.13 x 10⁻⁶ m²
Therefore,
<u>L = 169.5 m</u>
