Work done by me for using force of 4 N to push an object 3 m away is 12 J.
<u>Explanation:</u>
Work done on any object is defined as the force required to displace that object from its original position. In other terms, the work done is the measure of force utilized for moving an object. So mathematically it is represented as the product of force with the displacement of the object due to that force.
Then, here it is given that force of about 4 N is used to displace the object to 3m. Thus,
So, 12 J of work is done by me to push an object 3 m away with the force of 4 N.
Answer:the answer is A I think, tell me if I’m wrong
Explanation:
A wave is a disturbance that carries energy from one place to another. Matter is NOT carried with the wave! A wave can move through matter (a medium). If it must have a medium, it is called a mechanical wave.
Answer:
radio telescope
Explanation:
We use radio telescopes to study naturally occurring radio light from stars, galaxies, black holes, and other astronomical objects. We can also use them to transmit and reflect radio light off of planetary bodies in our solar system.
A suitable hypothesis might be that temperature affects the rate of chemical modification, and the independent variable is temperature.
<h3>What is a hypothesis?</h3>
A hypothesis is a given explanation about a question that emerged by observing form the real world.
In this case, the dependent variable is the rate of chemical modification because this variable is modified in the experiment.
In conclusion, a suitable hypothesis might be that temperature affects the rate of chemical modification, and the independent variable is temperature.
