Answer:
W = 0.562 J
Explanation:
Initial potential energy of two point charges is given as
here we have
now we have
now at final position the distance between two charges is given as
Now final energy is given as
Now the work done to change the position of charge is given as
Answer:
a. absorbed
Explanation:
This is because for the internal energy of the sidewalk to increase, its temperature and thus its internal energy must increase. This causes it to heat up and this is done by absorbing energy from the UV wave.
Explanation:
Solution,
- Mass(m)= 60 kg
- Force (F)= 20 N
- Acceleration (a)= ?
We know that,
- F=ma
- a=F/m
- a=20/60
- a=0.333 m/s²
So, her acceleration is 0.333 m/s².
Do the data support or refute the hypothesis, normally, the data for the first part of the experiment support the first hypothesis.
<h3>What is a hypothesis test?</h3>
Hypothesis testing refers to the formal procedures used by statisticians to accept or reject these hypotheses. When trying to make decisions, it is convenient to formulate assumptions or conjectures about the populations of interest, which consist of considerations about their parameters.
As a result of this, we can see that from the complete text, there is a set of data which is used to show the force that is applied to a cart that causes the acceleration of the cart to increase which supports Newton's second law.
