Answer:
Explanation:
We can use the following kinematics equations to solve this problem:
.
Using the first one to solve for acceleration:
.
Now we can use the second equation to solve for the distance travelled by the airplane:
(three significant figures).
The answers are; air, fuel, back, forward
The jet engine utilizes the principle that for every action force there is an equal reaction force in the opposite direction. When the exhaust from the combustion in the engine is ejected with great force backwards, the reaction force pushes the plane forward with an equivalent force.
Hm pretty much that's all for alpha decay... But always after any alpha or beta decay, gamma photons are released because the daughter products end up in an excited state so they have to release energy through gamma decay
The answer is
-Small f and large D.
The explanation:
-when The car jack is an example of a machine, which is defined as anything that a person can use to make the exertion of force easier.
-So with the small force he exerts on the jack, the distance that the car is lifted up increases
.
and People needs help of machines to increase their force. People cannot lift a car without a machine. Using the leverage or hydraulic principles the machines increase your force.
If you use a large leverage you execute a large movement with little force and as result the other side will move small distances with a greater force.
