Answer:
X Component is 183.85N
Explanation:
The x component of the force on the block due to the rope;
X = F cos @ where if is the force, @ is the angle mad with the block.
X = F cos @
X = 240 cos 40
Cos 40= 0.7660, so
X = 240 × 0.7660
X component= 183.85N// rounded to two decimal places.
In a quarter of an hour it will travel 1/4 x 90 = 22.5Km
Answer:
.
Fusion powers the Sun and stars as hydrogen atoms fuse together to form helium, and matter is converted into energy.
nuclear fission reactors include the possibility of radiation-releasing nuclear accidents, the problems of radioactive waste disposal, and the possibility of contributing to nuclear weapon proliferation
Answer: The combined velocity = 0.413m/a
Maximum angle Ø = 54.7
Explanation: Please find the attached files for the solution
So, the energy change that occurs is 190.512 J.
<h3>Introduction</h3>
Hello ! I am Deva from Brainly Indonesia will help you regarding energy and its transformation. In this case, it's the use of energy from the lifter to be equivalent to the change in the object's potential energy. Why potential energy? Because the box undergoes a change in height and the potential energy specializes at a certain height. Work (W) due to change in potential energy (
) can be realized in the equation :



With the following condition :
- W = work of subject (J)
= change of potential energy (J)- m = mass (kg)
- g = acceleration of the gravity (m/s²)
= final height (m)
= initial height (m)
<h3>Problem Solving</h3>
We know that :
- m = mass = 3.6 kg
- g = acceleration of the gravity = 9.8 m/s²
= final height = 5.4 m
= initial height = 0 m
What was asked :
- W = work of subject = ... J
Step by step :





So, the energy change that occurs is 190.512 J.
