Answer:
A sea breeze describes a wind that blows from the ocean inland towards land. ... However, water heats up much more slowly than land and so the air above the land will be warmer compared to the air over the ocean. The warm air over the land will rise throughout the day, causing low pressure at the surface.

This should be right!

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?
Answers
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
. How much power is used to move a 5 kg mass 28 meters in 8 seconds?
Answers
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
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.
Answers
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.

Do you think scientists should continue to explore nuclear energy as a source of electricity? Explain your opinion and provide reasons. Include an opposing opinion about another energy source.
Answers
Answer:
See explanation
Explanation:
Nuclear energy refers to energy trapped in the nucleus of atoms. Nuclear energy holds the greatest promise for large scale electricity generation. For instance, the amount of energy released by a given mass of uranium is 2.5 million times the energy released by combustion of an equal mass of carbon.One gram of uranium produces the same energy as 1 ton of coal, 17000 cubic feet of natural gas, 5000 pounds of wood and 149 gallons of oil.
Nuclear energy does not pollute the atmosphere as fossil fuels do. However, the challenges of effective control of the nuclear reactor and disposal of radioactive waste still remain a serious concern.
However, exploitation of nuclear energy as a source of electricity remain expensive and it is not quite easy to set up a nuclear power plant. Not many countries can afford to pay for the services of experts who operate nuclear energy plants talk more of providing the required equipment.
the diagram below shows different weights on the see-saw. Will the see-saw move?
Answers
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.

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?
Answers
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

Speed of sound at 22°C = ?
d = ?
You will be reported if you didn't answer properly
Answers
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

(c) Why is the telescope adjusted for a distant object in a spectrometer
Answers
Answer:
The telescope is adjusted to receive parallel rays by turning it towards a distant object and adjusting the distance between the objective lens and the eyepiece to get a clear image on the cross wire.
The telescope is turned towards a far-off object, and the distance between the objective lens and the eyepiece is adjusted to produce a clear image on the cross wire.
What is telescope?A telescope is a tool for creating enlarged views of far-off things. The telescope is without a doubt the most significant research tool in astronomy. It offers a way to gather and examine radiation coming from astronomical objects, even those at the edge of the cosmos.
When Galileo used the telescope to investigate alien bodies in the early 17th century, he revolutionized astronomy.
Magnification tools had never been employed for this purpose before until that point. The distance between the objective lens and the eyepiece is adjusted to provide a crisp image on the cross wire as the telescope is pointed towards a distant object.

Memories

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........

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.
Answers
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
