Answer:
Invitational Workshop
An invitational workshop is what many of us know. It’s what Lucy Calkins has made famous through the Reading and Writing Workshop. In the invitational workshop, the instructor usually hosts a minilesson. This minilesson is intended to meet the needs of the majority of children in the classroom. Afterward, the children are “invited” to employ the skills or strategy for the minilesson during workshop time, where students work independently or in small groups
Explanation:
Compression ring prevents pressurized refrigerant from blowing past the piston into the crankcase is the false statement.
Answer: Option A
<u>Explanation:</u>
Compression rings seal the combustion chamber from crankcase and then transfer heat to the cylinder from the piston. The piston rings are present in an internal combustion engine or steam engine with multi functions. The functions of piston rings are,
- Ensuring the combustion chamber is tightly sealed as to reduce the loss of gas to crankcase
.
- Promoting heat transfer from the piston to cylinder wall
.
- Controlling engine oil consumption
.
- Optimizing the proper quantity of oil between piston and cylinder wall.
Answer:
22.90 × 10⁸ kg
Explanation:
Given:
Diameter, d = 0.02 m
ωₙ = 0.95 rad/sec
Time period, T = 0.35 sec
Now, we know
T= 
where, L is the length of the steel cable
g is the acceleration due to gravity
0.35= 
or
L = 0.0304 m
Now,
The stiffness, K is given as:
K = 
Where, A is the area
E is the elastic modulus of the steel = 2 × 10¹¹ N/m²
or
K = 
or
K = 20.66 × 10⁸ N
Also,
Natural frequency, ωₙ = 
or
mass, m = 
or
mass, m = 
mass, m = 22.90 × 10⁸ kg
