The answer is a. endothermic.
In endothermic reaction, as the name suggests, the reactants require energy absorption to form and complete the chemical reaction to form products.
And even if you don't know the answer, you can exclude all other answers by scientific logic and you will be left with the correct answer.
Hope this helps.
Answer:
The vertical distance traveled is 3.18 m.
Explanation:
In order to find the vertical distance traveled by a body in free fall motion, starting from rest to a velocity of 7.9 m/s. For this purpose, we use Newton's third equation of motion,
2as = Vf² - Vi²
where,
a = g = 9.8 m/s²
s = vertical distance = Δy = ?
Vf = final velocity = 7.9 m/s
Vi = initial velocity = 0 m/s
Therefore,
2(9.8 m/s²)Δy = (7.9 m/s)² - (0 m/s)²
Δy = (7.9 m/s)²/(2)(9.8 m/s²)
<u>Δy = 3.18 m</u>
Answer:
a) 86 atm
b) 86 atm
c) 645 m/s
Explanation:
See attachment for calculations on how i arrived at the answer
We have that the the scenarios the flux is behavior is as follows:
- Here The -ve charge placed outside the surface will not affect the total flux charge.
- We have that the flux remains constant.
- Here with the <em>negative </em>charge outside, the flux will decrease.
- This will not affect net flux change, whereas if it where inside.It will increase flux.
Generally for each change
A positive charge is placed just inside the surface:
Here The -ve Charge placed outside the surface will not affect the total flux charge.
The charge is moved of-center by an amount equal to half the radius of the spherical surface.
We have that the flux remains constant.
A negative charge is placed just outside the surface.
Here with the <em>negative </em>charge outside, the flux will decrease.
A <u>positive </u><em>charge </em>is placed just outside the surface.
This will not affect net flux change, whereas if it where inside.It will increase flux.

Complete Question
A positive point charge is placed at the center of an imaginary spherical surface. As a result, there is some total electric flux outward through the surface. For each change listed, how would the total outward flux though the surface change?.

- A negative charge is placed just outside the surface.
- A positive charge is placed just outside the surface.
Her weight doesn't change but thats only simply because there is no gravity in space.
