Answer:
0.0003758 m²
Explanation:
The formula to apply is;
ΔL=1/Y *F/A*L₀
Where ΔL=change in length = 0.412 in
Y=modulus of elasticity=30000000 psi
change psi to Pa
1 psi= 6.894757 kPa
30000000=?
6.894757 *30,000,000 =206842710000 Pa
F=applied force = 12000 lb---change to Newtons
1 lb=4.4482189159 N
12000 lb=? 12000*4.4482189159 =53378.6 N
A=cross-sectional area=?
L₀=original length of the rod= 50 ft ----change to meters
1ft =0.3048
50 ft=50*0.3048=15.24 m
ΔL =0.412 in -----change to meters
1 in =0.0254
0.412 in =? 0.412*0.0254 =0.0104648 m
Applying the formula
ΔL=1/Y *F/A*L₀
0.0104648 =1/206842710000 *(53378.6/A)*15.24
142031994.2=53378.6/A
A=53378.6/142031994.2
A=0.0003758 m²
Answer:
8.62m/s²
Explanation:
the particle is experiencing both translational and circular motion
v=4t²
==8t
at t=1s, =8(1)=8m/s²
=
at t=1, v= 4(1)² = 4m/s
=4²/5
=3.2m/s²
∴ magnitude of total acceleration, a
a=
a=
a=
a=
a=8.62m/s²
A design is a plan or specification for the construction of an object or system or for the implementation of an activity or process, or the result of that plan or specification in the form of a prototype, product or process. The verb to design expresses the process of developing a design.

<h3>
Option A</h3>
In a Series circuit with two identical loads, the voltage across each load will be: the same
<h3><u>
Explanation:</u></h3>
A series circuit is one with total the loads in a row. There is barely ONE path for electricity to pass. If this circuit was a series of flashbulbs, and one left out, the left bulbs would switch off. T
he current in a series circuit is universally the same and the voltage over the circuit is the amount of the unique voltage drops over each component. The voltage referred to as a series circuit is equivalent to the amount of the individual voltage drops.
