Answer:
The helicopter uses 35 gallons to fly for 5 hours.
Explanation:
The amount of gas that a helicopter uses for flying varies directly proportional to the number of hours spent flying.
g ∝ T
where g represents amount of gas and T time of flight.
Then,
The helicopter files 4 hours and uses 28 gallons of fuel.
Here, g₁= 28 gallons, T₁=4 hours
g₂=?, T₂=5 hours.
⇒28×5= g₂×4
⇒ g₂×4=28×5
gallons
The helicopter uses 35 gallons to fly for 5 hours.
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?.

Answer:
L = 3.35 m
Explanation:
given,
mass of the block = 0.2 Kg
spring constant = 1.40 kN/m
until spring compressed = 10 cm
inclination of ramp = 60°
now,
initial potential energy of spring = (work done by friction) + (final gravitational potential energy of block)
L = 3.35 m
