if Circle one 100 g (least massive) and 200 g (most massive) have the same material then the least massive i.e 100g heat faster.
what is specific heat?The amount of heat required to raise the temperature of an object is proportional to its mass. Specifically, the heat required is given by,
the formula
Q = m × c × ΔT
Where Q= is the amount of heat required
m= is the mass of the object
c= is the specific heat capacity of the material, and ΔT is the change in temperature.
If the two samples are made of the same material and have the same initial temperature, their specific heat capacities and the change in temperature will be the same.
Then, the amount of heat required to raise the temperature of the 100 g sample will be half that of the 200 g sample. This means that the 100 g sample will heat up more than the 200 g sample, as it requires less heat to raise its temperature.
Therefore, The sample with 100 g (least massive) will heat up faster than the sample with 200 g (most massive) if both samples are made of the same material and have the same initial temperature.

How high will the ball go? I would really appreciate a step by step answer!
Answer:
y = 3.26 [m]
Explanation:
In order to solve this problem, we must use the following equation of kinematics.
[tex]v_{f}^{2}= v_{o}^{2}-2*g*y[/tex]
where:
Vf = final velocity = 0
Vo = initial velocity = 8 [m/s]
g = gravity acceleration = 9.81 [m/s²]
y = elevation [m]
Note: The negative sign in the equation above represents that the movement is againts the direction of the gravity acceleration.
Now replacing:
[tex]0=8^{2} -2*9.81*y\\19.62*y=64\\y=3.26 [m][/tex]

Answer:
6km
Explanation:
For this graph to the right, what is the
velocity of the object? Show your work.
I dont see a mark where it is, if there was a line it would be marking the constant speed of it. There is just time(s) which probably stands for speed, and position(m) which probably stands for miles. There is a measurement of 50, down to 10.

Selective breeding has been used to create plants that are more resistant to disease. Of what is this an example? A an organism being used as part of a technological process B an organism being changed through technological methods C a new technology inspired by the natural structure of a living organism D a new technology being directly developed from the structure of an organism
Answer:
B. an organism being changed through technological methods
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments. One of the most important branch of science is bioengineering. Bioengineering can be defined as a high-tech process which avail scientists the opportunity or ability to modify, remove, replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
Selective breeding has been used to create plants that are more resistant to disease. Thus, this is an example of an organism being changed through technological methods.

The density of molten copper is 7900 kg/m3.
Explain this difference in density by referring to the particle model and the arrangement of
atoms in the two states. (2)
Explanation:
The density of a solid copper is 8960kg/m^3 while the density of a molten copper is 7900kg/m^3 this is due to the difference in the state of matter, the solid copper is in solid state while the molten copper is in form of a liquid. In the solid copper atoms are tightly pack while they atom are not tightly packed.

What is the relationship between the force of gravity and the distance between the two objects involved?
Answer:
They are inversely proportional
Explanation:
The force of gravity and the distance between two objects involved are inversely proportional to one another.
According to newton's law of universal gravitation "the force of gravity between two bodies is a product of their masses and inversely proportional to the distances between them".
The force of gravity and distance between two bodies are inversely related. The larger the distance between two bodies the lesser the force of gravity between them.Gravity and inertia are the two forces that keep Earth in its orbit as it travels around the Sun. What would happen if the force of inertia disappeared?
A.
Earth would leave the solar system.
B.
There would be no changes in Earth's orbital path.
C.
Earth would break apart.
D.
Earth would be pulled into the sun.

How are electromagnetic waves different from sound or water waves?
Explanation:
Electromagnetic waves are different from sound or water waves in such a way that water and sound waves are called mechanical waves that requires a material medium for their propagation.
Electromagnetic waves do no require a material medium for propagation.
Electromagnetic waves are carried or transported by radiation and this can be passed through vacuums and different other materials. But mechanical waves such as water and sound waves requires a material medium for their propagation. They cannot pass through a vacuum.calculate the density of gold if 96500kg mass of gold is adjusted in the volume of 5m cube

What is the connection to Canadian technology/development with the Kepler space telescope?
Answer:One of this country's most notable achievements will be spending Canada Day weekend marking its own milestone anniversary in a unique place, floating up in space.
After 10 years in the ether, several times farther from Earth than the International Space Station, it remains the world's smallest space telescope.
MOST was also Canada's first-ever space telescope when it was launched into space on June 30, 2003.
It has helped make Canada a leader in the field of micro satellites.
But Matthews is particularly enthused about all the other possibilities that might be opened up by the 60-kilogram MOST.
The colorful University of British Columbia astrophysicist firmly believes there is life outside our solar system.
"Certainly simple forms of life like microbial life is probably very common — and I hope complex life," Matthews said in a recent interview. "If it's out there, we're finding the places where it's most likely to live."
I have no Idea if this helps but hope it does.

Zach drives his car around a circular section of a road having a radius of 50 meters at a constant speed of 20 m/s. What is the centripetal acceleration of Zach's car?
Answer:
Centripetal acceleration = 8m/s²
Explanation:
Given the following data;
Radius, r = 50m
Velocity, v = 20m/s
To find centripetal acceleration;
Centripetal acceleration = v²/r
Centripetal acceleration = 20²/50
Centripetal acceleration = 400/50
Centripetal acceleration = 8m/s²
Therefore, the centripetal acceleration of Zach's car is 8 meters per seconds square.
In what direction do the velocity vectors point in circular motion?
The velocity vector is always perpendicular to the radius. By radius, I mean the inward centripetal force that pulls the object to continue on its curved path. Without this inward force, the object would continue on a straight path tangential to the curve it was previously on.

Missy's favorite ride at the Topsfield Fair is the rotor, which has a radius of 4.0 m. The ride
takes 2.0 s to make one full revolution. a) What is Missy's linear speed on the rotor? b) What is
Missy's centripetal acceleration on the rotor? If her mass is 50-Kg, how is the centripetal force
compare to her weight?
Answer:
a. 12.57 m/s b. 39.5 m/s² c. Her centripetal force is four times her weight.
Explanation:
a. What is Missy's linear speed on the rotor?
Missy's linear speed v = 2πr/T where r = radius = 4.0 m and T = time it takes to complete one revolution = 2.0 s
So, v = 2πr/T
= 2π(4.0 m)/2.0 s
= 4π m/s
= 12.57 m/s
b. What is Missy's centripetal acceleration on the rotor?
Missy's centripetal acceleration, a = v²/r where v = linear velocity = 12.57 m/s and r = radius = 4.0 m
a = v²/r
= (12.57 m/s)²/4.0 m
= 158.01 m²/s² ÷ 4.0 m
= 39.5 m/s²
c. If her mass is 50-Kg, how is the centripetal force compare to her weight?
Her centripetal force F = ma where m = mass = 50 kg and a = centripetal acceleration = 39.5 m/s².
Her weight W = mg where m = mass = 50 kg and g = acceleration due to gravity = 9.8 m/s².
So, comparing her centripetal force to her weight, we have
F/W = ma/mg
= a/g
= 39.5 m/s² ÷ 9.8 m/s²
= 4.03
≅ 4
So her centripetal force is four times her weight.
