How far apart do you mark the perimeter of a minefield?
How far apart do you mark the perimeter of a minefield?
For conventional minefields, ensure that the perimeter fence is at least 15 meters outside the nearest mine or cluster.
What is EOR quizlet?
Explosive Ordnance Reconnaissance (EOR)
What does a low order explosive material resemble?
What substance does a low-order explosive resemble when exposed to air and sunlight? dark brown rocks.
What is a true statement about projectiles?
The horizontal velocity of a projectile is constant during its flight. This statement is true because there is no accelerating force…
What is the path of a projectile called?
Projectile motion is a form of motion where an object moves in parabolic path; the path that the object follows is called its trajectory.
What force keeps an object from reaching the ground?
What if I push an object which is already moving horizontally?
Thus, force would cause. acceleration in horizontal motion.
What happens when two objects collide?
In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).
Why do you need to use force in moving a ball up a ramp?
(C) is the answer because when ball is rolling up the plane then gravitational force acting opposite to the motion of ball and responsible for the reducing velocity of centre of mass of ball while frictional force acting up the plane at contact point of ball responsible for reducing rotational velocity of ball.So both …
Is a Force push or pull?
A force is a push or pull upon an object resulting from the object’s interaction with another object.
How do you explain push and pull?
Basically, objects move through force. All forces are either push or pull. When force moves an object away from something, that is a push. When force brings an object closer, that is a pull.
What are examples of push and pull?
Push and pull are the forces that are used to put an object into motion….Examples
- Thumb Pins.
- Opening and Closing a Door.
- Pushing a Car.
- Pulling a Cart.
- Inserting and Removing a Plug.
- Water Dispensers.
- Pulling Curtains and Blinds.
What are examples of push?
Push is defined as an action or a force which causes an object to move from its place or from the state of rest.
- Moving a car which has stopped working.
- Squeezing wet clothes.
- Closing a door.
- Moving objects across a plank.
- Inserting a bell pin to file papers together.
- Inserting a plug into a socket.
What are 3 push factors?
3) Push Factor: Freedom from Political Oppression, Conflict, and Chaos: British political activists of the early 19th century, the German “Forty-eighters” in the middle of that century, and Cuban and Hungarian dissidents in the 1950s, are examples of a few of the groups that tried to reform the governments of their …
What is force explain with two examples?
A force involves an interaction between two or more objects, and it causes a push or pull between the objects. Good examples of opposing force include drag due to interaction with an air mass and the force due to friction between two objects.
What are the 10 types of forces?
Types of Forces
|Contact Forces||Action-at-a-Distance Forces|
|Frictional Force||Gravitational Force|
|Tension Force||Electrical Force|
|Normal Force||Magnetic Force|
|Air Resistance Force|
What are 4 examples of force?
Common Examples of force are:
- Electric force.
- Magnetic Force.
- Nuclear force.
- Frictional force.
- Normal force.
- Force of Gravity.
What are the two types of forces?
There are 2 types of forces, contact forces and act at a distance force. Every day you are using forces. Force is basically push and pull. When you push and pull you are applying a force to an object.
What are the 3 types of non contact forces?
The three types of non-contact forces are gravitational force, magnetic force, electrostatic and nuclear force.
What are two natural forces?
Natural forces introduction
- Gravitational force.
- Electromagnetic force.
- Strong nuclear force.
- Weak nuclear force.
How many different forces are there?
The four basic forces are the gravitational force, the electromagnetic force, the weak nuclear force, and the strong nuclear force. Their properties are summarized in Table 1.
What are the four main types of resistance forces?
The four main resistance forces are objects with mass, inertia, and momentum; friction; gravity; and air resistance.
What are the two forces acting on the box?
Answer. Explanation: the force of gravity and the normal force.
Are the two forces acting on the box balanced?
The two forces are balanced. forces that are acting in the same direction, add them together. For example, if you pull on a box with a force of 25 newtons (N) while your friend pushes the box (in the same direction you are pulling) with a force of 30 N, the net force applied to the box in that direction is 55 newtons.
What is the normal force acting on the box?
We can immediately determine that our answer will also have one significant figure however, to maintain accuracy, we will only round for precision after the final calculation. The normal force acting on box is equal and opposite to the weight of the box.
Does a balanced force have direction?
Balanced forces are those that are opposite in direction and equal in size. Balanced forces are considered to be in a state of equilibrium. When forces are balanced there is no change in direction. Balance forces cannot change the motion or direction of an object.
What are 3 examples of balanced forces?
Here are some examples of situations involving balanced forces.
- Hanging objects. The forces on this hanging crate are equal in size but act in opposite directions.
- Floating in water. Objects float in water when their weight is balanced by the upthrust from the water.
- Standing on the ground.
