Answer:
102564.103 C
Explanation:
From the question given above, the following data were obtained:
Energy (E) = 4000 J
Potential difference (V) = 0.078 V
Charge (Q) =?
Thus, we can obtain the charge as illustrated below:
E = ½QV
4000 = ½ × Q × 0.078
4000 = Q × 0.039
Divide both side by 4000
Q = 4000 / 0.039
Q = 102564.103 C
Thus, the charge is 102564.103 C.
Memories
by matthew smith
I remember when I met you
the smile on your face,
Seems like a million years ago -
a different time and place
I remember when I kissed you
the warmth inside my heart,
I thought it'd last a lifetime
I swore we'd never part
I thought about the future
I started making plans,
Forever you'd be my woman
forever I'd be your man
We went together places
so that everyone could see,
The women that I want to share
the rest of my life with me
I told you that I loved you
I told you that I cared,
I told you if you were falling
just look back and I'd be there
I know I didn't have all the answers
sometimes I only guessed,
But, through it all I have to say
"I always tried my best"
I wasn't always perfect
I wasn't always right,
I know sometimes I wasn't
even worthy in your sight
I know I took for granted
the love you had to share,
All I ever wanted was
for you to know I cared
Our lives have changed directions
as sometimes lovers do,
Often time and change
and pave a path that's new
Sometimes I often wondered
just what lies ahead,
Sometimes I'd like to turn back time
and take back what I said
We've both gone different places
we've both gone different ways,
I know sometimes I let you down
when trouble came our way
I know sometimes I did things
you didn't comprehend,
But, through the years and all the tears
our memories will never end........

. How much power is used to move a 5 kg mass 28 meters in 8 seconds?
Answer:
171.5Watts
Explanation:
Given parameters:
Mass = 5kg
Distance = 28m
Time = 8s
Unknown:
Power = ?
Solution:
Power is the rate at which work is done;
Power = [tex]\frac{work done }{time taken}[/tex]
Work done = force x distance = mg x d =
m is the mass
g is the acceleration due to gravity
d is the distance
Work done = 5 x 9.8 x 28 = 1372J
Power = [tex]\frac{1372}{8}[/tex] = 171.5Watts
Why magnet is more powerful in poles than middle?
Answer:
The magnetic force or attraction is is greater where the field lines are crowded. Since all the magnetic field lines generate from the poles, the crowd of field lines is maximum near pole.
3. When should we perform stretching in relation to exercise (before, after or during), and what type of stretching should we be performing?
There is some evidence that regular static stretching outside periods of exercise may increase power and speed, and reduce injury. The best time to stretch is when the muscles are warm and pliable. This could be during a yoga or pilates class, or just after exercising.
What happens when the force of friction is more than the force of a moving object?
The object will slow down.
The object will be unaffected.
The object will continue at the same speed.
The object will speed up.
Inertia is a force which brings all objects to a rest position. Fast-moving objects have more inertia than slow-moving objects. False - The speed of an object has no impact upon the amount of inertia that it has. Mostly True - Two objects of the same mass can weigh differently if they are located in different locations.

A teacher walks back and forth in front of the room during a lesson. He starts at one end of the desk and walk from the door to the window a distance of 4.0m in 5 s. Then he stops, turn around and walk 2.0 m back toward the door in 3 s. He stops here for 10 s and then walk 3 meters toward the door in 6 s. Deduce the average speed of the teacher over the entire 24 s interval?
Answer:
0.375 m/s
Explanation:
The average speed of an object or a body is given by:
total distance traveled/total time taken
In the case of the teacher who walked back and fort:
Total distance traveled = 4.0 + 2.0 + 3 = 9 meters
Total time taken= 24 s
Hence,
Average speed of the teacher = 9/24
= 0.375 m/s

Calculate the pressure exerted by mercury column of 76cm high at its bottom. Given that the density of mercury is 13600kg/m³ and g=9.8 m/s².
Answer:
P = 101292.8
Explanation:
Use
Pressure p = H D g
H = height ( in metric)
D = density ( in metric )
g = gravity
So
H = 76 cm = 0.76 m
D = 13600 kg/m3
And g = 9.8
P = HDg
= 0.76× 13600×9.8
= 101292.8 pascal
Or = 1.012928 × 10^5

This is due today and I’m confused on this question
Answer: 5.4 kg
Explanation:"Recall that force is the result when we multiply the values of an object's mass and acceleration. Mathematically, we have
F = ma
where F is the force (in Newtons, N), m is the mass (in kilograms, kg), and a is the acceleration (in m/s²).
Since we know that the eagle was accelerating at 22.35 m/s² with a force of 120N, we can solve for the eagle's mass as shown below.
m = F/a
m = (120)/(22.35) ≈ 5.4 kg
Hence, the eagle has a mass of approximately 5.4 kg."

Byron measured the mass of a bag of cookies that he bought at the store and found that they were 45 grams. He set the cookies on the counter, but his little brother found them. His brother could not get the bag open so he smashed them to little pieces. What could Byron expect to find when he measured the mass of the cookies again?
Group of answer choices
They would be more than 45 grams since there are more pieces.
They would be 45 grams since they have the same mass.
They would be less than 45 grams since they were in little pieces.
The mass of the cookies would been reduced by 5 grams.
Answer:
They would be 45 grams since they have the same mass

4. A hiker leaves camp and using a compass walks 4 km East, 6 km South, 3 km East, 5 km North, 10 km West, 8 km North and 3 km South. What is his total displacement?
Answer:
Because the hiker walked directly west and then directly north the two legs of the hike forms a right triangle. Therefore we can use the Pythagorean Theorem to solve this problem.
c=5
The hiker is 5km from camp and should head in a generally south-east direction

which two changes would increase the electric force between two charged particles
In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.

the diagram below shows different weights on the see-saw. Will the see-saw move?
Answer:
yes it will
Explanation:
As the net torque on the see-saw is not equal to zero, the see-saw in the given diagram will move.
What is torque?The force that can cause an object to rotate along an axis is measured as torque. In linear kinematics, force is what drives an object's acceleration. Similar to this, an angular acceleration is brought on by torque.
As a result, torque can be thought of as the rotational counterpart to force. Torque is referred to using a variety of terms, including moment and moment of force. The moment arm or lever arm is the measurement of the separation between the point of application of force and the axis of rotation.
The net torque on the see-saw = 3 N × 1.20m - 8 N × 0.50 m
= - 0.4 N-m.
As the net torque on the see-saw is not equal to zero, the see-saw move will move.

In the middle of a thunderstorm, a lightning bolt flashes. It takes Roberto 5 seconds to
hear the thunder afterwards. How far is the source of lightning from Roberto? The temperature is 22° C.
Speed of sound at 22°C = ?
d = ?
You will be reported if you didn't answer properly
Answer:
v = 344.1 m / s
d = 1720.5 m
Explanation:
For this problem we must calculate the speed of sound in air at 22ºC
v = 331 RA (1+ T / 273)
we calculate
v = 331 RA (1 + 22/273)
v = 344.1 m / s
the speed of the wave is constant,
v = d / t
d = v t
we calculate
d = 344.1 5
d = 1720.5 m
