Answer:
- Calculate the time (in minutes) that it would take for the jet to cover the distance at the given speed.
- Multiply the time with the rate of burning of fuel by the jet.
Explanation:
<em>A military jet cruising at an altitude of 12.0 km and speed of 1200 km/h burns fuel at the rate of 80.1 L/min. How would you calculate the amount of fuel the jet consumes on a 750 km mission?</em>
In order to calculate the amount of fuel that would be consumed, <u>first, there is a need to find the time it will take to complete the 750 km mission</u>.
Recall that: speed = distance/time, at a speed of 1200 km/h, the time taken to cover a distance of 750 km would be;
time = distance/speed
= 750/1200 = 0.625 h
The rate of fuel burning is 80.1 Liters in a minute, there are 60 minutes in 1 hr;
1 hr = 60 minutes
0.625 h = 0.625 x 60 = 37.5 minutes
It takes 37.5 minutes to cover 750 km and the fuel burning rate is 80.1 liters per minute, hence, <u>the amount of fuel consumed by the jet would be;</u>
80.1 x 37.5 = 3000 liters
The bin will not move because the frictional force is greater than the net force acting on the bin.
<h3>What is the net force acting on the bin?</h3>
The net force acting on the bin is obtained by subtracting the force acting on the Easterly direction from that acting in the Westerly direction.
Net force = 110 N - 52 N
Net force = 58 N
The frictional force acting on the bin is determined as well using the given formula:
Frictional force = coefficient of static friction * normal reaction
Norma reaction = 26 * 9.81
Normal reaction = 255.06 N
coefficient of static friction = 0.25
Frictional force = 0.25 * 255.06
Frictional force = 63.8 N
Since the frictional force is greater than the net force acting on the bin, the bin will not move.
In conclusion, the frictional force is the force that opposes relative between two objects at their surface of contact.

The Solar electricity source of
energy comes from the sun’s rays. It is more often in the form of a panel known
as the solar panel. It has a photovoltaic system that generates and supplies
energy in commercial and residential areas. Countries are using this type of
electricity to save electric-induced power.
A gas stove uses chemical energy.

Answer:
Explanation:
Given that,
Charge density is λ = 12 nC/m
And radius 3cm
r=0.03m.
The charge density of a along a circular arc is given as
λ= Q/πr
Then, Q=πrλ
Q=π×0.03×12×10^-9
Q=1.131×10^-9 C
Q=1.131 nC
Then, electric field along x axis is symmetrical and if cancels out
Now, Ey is in the negative direction
Electric field is given as,
Ey=-2kQ/πr²
K is constant =9×10^9Nm²/C²
Ey=-2×9×10^9×1.131×10^-9/(π ×0.03²)
Ey=7200 N/C.
The direction is negative direction of y axis, check attachment for diagram.
b. Electric potential at the origin is given as
V=Ed
d=r=0.03
V=7200×0.03
V=216V
