It can help with measurements and when you want to add measurements to a cylinder or a beaker so ya
Answer:
c. length of the wall or column and the rate of placement of the concrete
Explanation:
when designing for wall and column form-works, it is of utmost important to know the length of the wall and the type of concrete placement to be used.
Concrete placement has methods and precaution to be taken when doing the form work
if the concrete placement is manually (hand or funnel) the form work height should not be more than 1 m to enable easy compaction and vibration of concrete in the form.
Also, if the form work length is too long and it is not well reinforced, it tends to burg if the force apply during concrete placement or during vibration is much.
Answer:
0 m/sec
Explanation:
b/c they were at rest and initial means at rest ,at rest means 0 HOPE THIS HELPS
Explanation:
It is given that,
Length of solenoid, l = 28 cm = 0.28 m
Area of cross section, A = 0.475 cm² = 4.75 × 10⁻⁵ m²
Current, I = 85 A
(a) The inductance of the solenoid is given by :
L = 0.0000886 H
(b) Energy contained in the coil's magnetic field is given by :
U = 0.3200675 Joules
or
U = 0.321 Joules
Hence, this is the required solution.
