Answer
given,
mass of the solid door = 22 Kg
dimension of door = 220 cm x 91 cm
moment of inertia about the hinge
r is the distance from the one edge which is equal to 91 cm or 0.91 m
Moment of inertia about center for rectangular gate is equal to
moment of inertia for rotation about a vertical axis inside the door, 15 cm from one edge
The force is 1.5N acting downward or -1.5N.
Why?
To answer this question, we need to remember the Newton's Third Law. This Law states that for every force applied upon an object, there is an equal force acting in the opposite direction. This Law is also called "action-reaction Law".
So, if the force of the players heads applied on the ball is equal to 1.5N (upward), the force applied by the force on the players heads will be exactly equal, but with opposite direction, or -1.5N (downward).
Have a nice day!
Physical education is one of if not the most important aspect of school, and something we can immediately transfer over to our lives. Personally, I think physical education is a must in every school and every grade level. Children are becoming more obese due to the delicious taste of fast food and how easy it is to sit on video games for hours. Kids need to know that you should not be eating at mcdonald’s every day, and instead, meal prepping. The benefits of nutrition are phenomenal including but not limited to, increased muscle size and mass, a decrease chance of heart attack, decreased chance of major artery failure etc. If you take care of your body now, you won’t have to face the consequences when you are older, and if you adopt a healthy, active lifestyle now, not only will your heart thank you, but so will your future self, for those extra few years of life you got to spend happy, and fulfilled. — I hope this is what you were looking for!
Answer:
Oblique surface
Explanation:
Surfaces or lines situated at an angle in relation to all the main projection planes are oblique. An oblique surface never appears in any of the main perspectives as a line or true size area. It's Tipped to all main projection planes. doesn't quite appear on the edge of every standard view. doesn't quite show up in any view in true size.it has always been foreshortened.
