A force of 45 newtons is applied on an object, moving it 12 meters away in the same direction as the force. What is the magnitud
1 answer:
<h2>Answer: 540 J</h2>
Explanation:
The Work done by a Force
refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path.
Now, when the applied force is constant and the direction of the force and the direction of the movement are parallel, the equation to calculate it is:
(1)
In this case both (the force and the distance in the path) are parallel (this means they are in the same direction), so the work performed is the product of the force exerted to push the box
by the distance traveled
.
Hence:
(2)

Explanation:
Now this question is a tricky one because all of these options are somehow involved in radioactive decay; however, in this case the SYMBOL is required NOT the elements. There are three symbols involved in radioactive decay, which are:
1. α for alpha decay
2. β for beta decay
3. γ for gamma decay
In the options only one symbol is present which is gamma. Hence option (D) Gamma ( ) is the correct answer.

Answer:
Explanation:
From the question we are told that
Velocity v=28m/s
Distance d=280
Generally the Newtons equation for motion is mathematically given as
Acceleration
Answer:
The velocity is
Explanation:
From the question we are told that
The electric field is
The magnetic field is
Generally the force experienced by the electron due to the magnetic field is
Generally the force experienced by the electron due to the electric field is
Since from the question the net force is zero then
=>
Substituting values
