Answer:
Therefore, the spring constant of each spring = 1.6 × 10⁻⁶ kg/s².
Explanation:
The period (T) of a spring in oscillation = 2π √(m/k)............. equation 1
Where m = mass acting on the spring (kg), k = spring constant of the spring (kg/s²).
Making k the subject of equation 1
k = T²/(4π²×m) .......................... equation 2
From the question, F = 4.42 Hz,
since T = 1/F
then, T = 1/F = 1/4.42 =0.226 s, π = 3.143
since the weight of the mass is evenly distributed over the four identical spring, Hence
m = 1450/4 = 362.5 kg
Substituting these values into equation 2
k = 0.226/{(4×3.143²)362.5}
k = 0.226/(14323.751)
k = 0.0000016 kg/s²
k = 1.6 × 10⁻⁶ kg/s².
Therefore, the spring constant of each spring = 1.6 × 10⁻⁶ kg/s².
What happens is that if u put gas in a ball and placed in a hot climate it will start burning Bc u have gas inside the ball
Answer:
The electrical potential energy is 0.027 Joules.
Explanation:
The values from the question are
charge (q) = 
Electric Field strength (E) = 
Distance from source (d) = 0.030 m
Now the formula for the electrical potential energy (U) is given by
So now insert the values to find the answer

Answer:
563.86 N
Explanation:
We know the buoyant force F = weight of air displaced by the balloon.
F = ρgV where ρ = density of air = 1.29 kg/m³, g = acceleration due to gravity = 9.8 m/s² and V = volume of balloon = 4πr/3 (since it is a sphere) where r = radius of balloon = 2.20 m
So, F = ρgV = ρg4πr³/3
substituting the values of the variables into the equation, we have
F = 1.29 kg/m³ × 9.8 m/s² × 4π × (2.20 m)³/3
= 1691.58 N/3
= 563.86 N
Answer:
The correct option is;
Biochemist → Archivist → Civil Engineer → Engineering Technician
Explanation:
1) Biochemist require the completion of a science degree or applied science degree, while biochemist usually hold a PhD to perform research independently, while entry level positions in the profession require a masters or bachelors degree
The PhDs usually require about 5 years to complete, after obtaining the masters degree
2) The general educational requirement to become an archivist is a master's degree in the fields of library science, history, public administration, political science, or archival science, which requires the completion of a bachelors degree followed by the completion of the masters degree which is thus 4 to 6 years
3) Civil engineer title is awarded to holders of a bachelors degree in Civil Engineering which gives the strong mathematical and science background required in the profession usually. The Civil Engineering program duration is five years
4) The engineering technician consist of 8.2% with masters degree, 42.0% have bachelors degree, while it is also possible to become an engineering technician with a GED or a high school degree
Therefore, the usual duration of study to become an engineering technician is two years of an associate degree program.
