Answer:
The types of solenoids are: AC Laminated Solenoid
, DC Solenoid
, Linear Solenoid
,and Rotary Solenoid. 
Explanation:
- The main purpose of solenoid is to generate the controlled magnetic field that can be used in many forms.
- The most common use of solenoid is done in the pinball game.
- The Flipper solenoid that uses the two coil are used in the mechanism of pinball machines.
- One coil of the solenoid is supplied with high electric current where as other one has the weak current flowing through it.

Answer:
"Narrow the focus of research question"
Explanation:
O Narrow the focus of research question 
     This is good! You can still use your question, but focus in on something so you have a proper research project.
O Add another research question 
     Would adding another question to an already broad question help? No.
O Use the very first source you find for your project 
     If your question is too broad, you should not use whatever you see first as it may be incorrect or does not answer the question
O Change the scope of your project     
     You could, but if you have a set scope for your project (a) you might not be able to change it (b) you don't need to restart
Have a nice day!

Answer with Explanation:
We are given that 
Mass of box=35 kg
Coefficient of static friction between box and truck bed=0.202
Acceleration due to gravity=
a.We have to find the force by which the box accelerates forward.
Force by which box accelerates=
Force by which box accelerates=
b.We have to find the maximum acceleration can the truck have before the box slides.
Force =friction force 


Hence, the truck can have maximum acceleration before the box slide=
 
        
             
        
        
        
Answer:
 shirt is little attached to the body, it can come off and fly away
Explanation:
In electrostatics, charges of different signs attract and charges of the same sign repel.
In this case, when a negative charge is placed on it, both the inventor and the shirt are charged, therefore there is a repulsive force, also there is an attraction between the positive charge of the roof attracts the negative charge, such as the shirt. of weak the two forces not greater than the resistance of the walk.
As the shirt is little attached to the body, it can come off and fly away
