Answer:
It has producer-consumer relationship with sugar-maple trees because it gets food from the trees.
Explanation:
The mourning bird is primarily a seed eater and not an insect eater. Since it is a seed eater, it will directly from the sugar-maple tree which is the producer.
In an ecosystem, the producers are plants which can trap energy directly from the sun during photosynthesis. This energy is passed on to the consumers.
Hence, the mourning bird has producer-consumer relationship with sugar-maple trees because it gets food from the trees.

An egg sinks in fresh water but floats on concentrated salt solution
the salt solution exerts a greater up thrust on the egg which balances the weight of the egg, so the egg floats in a strong salt solution but sinks in fresh water

PLEASE HELP ME,, I WOULD BE SO HAPPY
You push against a wall with all your might and generate an insane 2500N of force. However, the wall doesn't move. How much work did you do?PLEASE HELP ME,, I WOULD BE SO HAPPY You push against a wall with all your might and generate an insane 2500N of force. However, the wall doesn't move. How much work did you do?
Answer: None
Explanation:
Since the wall did not move, it does not matter how much force you generated. You did no work in the physics sense.
Work is calculated by multiplying the displacement by the force. Since there was no displacement (no movement) we put the value as 0. 0 times anything is still 0, as shown below.
2500 N * 0 = 0.
You did no work, or 0 J of work.

What is the acceleration of a car that goes from Om/s to 60m/s in 6 seconds?
10m/s !!!!!!!!!!!!!!!!!!!!!!!
A car of mass 800 kg goes round a corner of radius 65 m at a
speed of 10 m/s.
a) What size force is needed to achieve this?
b) Suggest how this force is likely to be obtained.
c) What force would be needed if the driver approached the
bend at twice the speed?
Answer:
a. Centrifugal force = 1230.77 Newton.
b. Centrifugal force = mv²/r
c. Centrifugal force = 4923.08 Newton.
Explanation:
Given the following data;
Mass = 800kg
Radius = 65m
Velocity = 10m/s
a. To find the force;
Centrifugal force = (800*10²)/65
Centrifugal force = (800*100)/65
Centrifugal force = 80000/65
Centrifugal force = 1230.77 Newton.
b. The force associated with the car is generally referred to as centrifugal force because it's the force required to keep the car in a curved or circular path. It can be calculated using the formula;
Centrifugal force = mv²/r
c. To find the force at twice the speed;
Velocity = 2 * 10 = 20m/s
Centrifugal force = (800*20²)/65
Centrifugal force = (800*400)/65
Centrifugal force = 320000/65
Centrifugal force = 4923.08 Newton.
a. To achieve a car of mass 800 kg goes round a corner of radius 65 m at a speed of 10 m/s , needed 1230.77 Newton centripetal forces.
b. When an object goes round a corner then centripetal forces keep that object moving in a curved path.
c. When speed is twice. then, 4923.07 Newton centripetal forces needed.
a. Given that car of mass 800 kg goes round a corner of radius 65 m at a
speed of 10 m/s.
Centripetal force ,[tex]F=\frac{mv^{2} }{r}[/tex]
Where m is mass, v is speed of object and r is radius.
Substituting all values in above equation.
[tex]F=\frac{800*10^{2} }{65} =1230.77Newton[/tex]
b. Centripetal force is defined as, the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation.
As a car makes a turn, the force of friction acting upon the turned wheels of the car provides centripetal force required for circular motion.
c. When speed is twice, then [tex]v=10*2=20m/s[/tex]
Centripetal force,[tex]F=\frac{800*20^{2} }{65} =4923.08Newton[/tex]

Explanation:
Consider two cylinders that start down identical inclines from rest except that one is frictionless. Thus one cylinder rolls without slipping, while the other slides frictionlessly without rolling. They both travel a short distance at the bottom and then start up another incline. (a) Show that they both reach the same height on the other incline, and that this height is equal to their original height. (b) Find the ratio of the time the rolling cylinder takes to reach the height on the second incline to the time the sliding cylinder takes to reach the height on the second incline. (c) Explain why the time for the rolling motion is greater than that for the sliding motion.
Answer:
a) m*g*hi = m*g*hf [tex]_{f}[/tex]
h[tex]_{i}[/tex] = h
b) ratio = 1.22
c) the potential energy is converted to both rotational kinetic energy and translational kinetic energy
Explanation:
For a frictionless system : initial energy = final energy
i.e. Ei = Ef
a) Prove
Total Initial energy for First cylinder ( Ei ) = m*g*hi
The final energy of the first cylinder ( Ef ) = m*g*hf
and this energies are purely potential energies
According to conservation of energy :
m*g*hi = m*g*hf
hi = hf ( and this holds for both cylinders because they where both kept at the same height initially )
i.e. initial height = final height ( hence it is proved that both cylinders will reach their initial heights )
b) Determine the ratio of the time taken by both cylinders
lets assume height of incline ( h ) = Lsin[tex]\beta[/tex]
where L = distance covered by cylinder
Final velocity of first cylinder ( V1 ) = [tex]\sqrt{\frac{4}{3} gLsin\beta }[/tex]
Final velocity of second cylinder ( V2 ) = [tex]\sqrt{2gLsin\beta }[/tex]
( following the application of the law of conservation of energy )
Given that ; Time taken = displacement / velocity
hence the ratio = ( h / v1 ) / ( h / v2 )
where h = Lsin[tex]\beta[/tex]
the ratio = 1.22
c) The time for the rolling motion is greater than the time for the sliding motion because the potential energy is converted to both rotational kinetic energy and translational kinetic energy

A rock is thrown straight up with an initial speed of 15.5 m/s . It is caught at the same distance above the ground . How high does the ball rise? How long does the ball remain in the air?
Answer:
The height risen by the rock is 12.26 mThe time spent in air by the rock is 3.16 sExplanation:
Given;
initial velocity of the rock, u = 15.5 m/s
at maximum height the final velocity of the rock, v = 0
The height risen by the rock is calculated as follows;
v² = u² - 2gh
0 = u² - 2gh
2gh = u²
h = u² / 2g
h = (15.5²) / (2 x 9.8)
h = 12.26 m
The time spent in air by the rock is known as time of flight, which is calculated as follows;
v = u - gt
0 = u - gt
gt = u
t = u/g
where;
t is the time to reach maximum height
t = 15.5 / 9.8
t = 1.58 s
Time of flight (time spent in air) is calculated as;
T = 2t
T = 2 x 1.58 s
T = 3.16 s.

When the C4 key on a piano keyboard is pressed, a string inside the piano is struck by a hammer and begins vibrating back and forth at approximately 260 cycles per second.
a. What is the frequency in Hertz of the sound wave?
b. What is the wavelength of the wave?
Answer:
Frequency = 260 Hz and wavelength = 1.31 m
Explanation:
Given that,
A hammer begins vibrating back and forth at approximately 260 cycles per second.
(a) The frequency of an object is the number of vibrations per unit time. The frequency of the sound wave is 260 Hz.
(b) The speed of sound in air is 343 m/s. So,
[tex]v=f\lambda\\\\\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{343}{260}\\\\\lambda=1.31\ m[/tex]

Answer:
1Burning of fossil fuel
2Deforestation
3Waste disposal in landfills
Explanation: took test:)
Human activities intensify the greenhouse effect as:
Deforestation -destroys natural carbon sinks, leading to more CO₂ in the air
Burning fossil fuels - the primary cause of human-created carbon emissions
Waste disposal in landfills - emits methane from decomposing matter
What is the greenhouse effect?The greenhouse effect can be defined as a process that occurs when energy heats the planet's surface, but greenhouse gases in the atmosphere stop the heat from returning directly to space and warm the earth.
The natural greenhouse effect retains the earth from freezing at the below-freezing temperature that it will freeze if there were no greenhouse gases. Human activities increase greenhouse gases and trap larger amounts of heat, which cause the Earth's temperature to grow warmer over time.
The Sun delivers most of its energy as visible light and near-infrared light, while the average surface temperature of the Earth emits longer-wavelength infrared IR and radiant heat. These gases emit radiant heat in all directions, traveling heat to the air and warming other greenhouse gases in the atmosphere.
