Substance A has twice the specific heat capacity as substance B. If 1000 J of heat are added to 1.0 kg of each substance, compare the change in temperature of each substance.
Answers
Q=mc x delta T
Q= heat energy in Joules
m= mass of substance heated or cooled
c= specific heat
ΔT is change in temp.
Solve for change in temp=. Q/mc
Specific heat and mass are not inversely proportional to heat energy input.
Putting into real world scenario of using water to heat a building.
Specific heat of water is 1.
It takes 1 btu to raise one pound of water 1 degF. at a base of 60 degF
Acetone specific heat is .51
So it takes half the amount of heat input to get a 100 degree ΔT, as compared to water.
You push on a light object (small mass) with a certain amount of force and it moves. If you push just as hard on a heavier object (large mass) it will move _____ the light object. a. Faster than b. slower than c. the same as
Answers
Answer: B
Explanation:
It will move slower than the light the object. The equation is Newton's 2nd Law of F = ma. If the force is constant, and the mass changes to something larger, then the acceleration must become smaller. You could also just do this yourself, push two objects with your hands. The heavier one will move slower assuming you used the same amount of force

Two masses oscillating together with each of their time period as ,'T'
To find↷New time period ,'T'Answer↷Option B
Time period is independent of mass so it will remain same irrespective of the mass on the spring so the new time period would be the exact same as the previous one.Solution↷we know that,
The time period of a mass 'm' on a spring of spring constant 'k' can be strategize by the following equation :
[tex] \huge \rightarrow \: T \: = 2π \sqrt{ \frac{m}{k} } [/tex]
m⇢mass of the body [kg]k⇢spring constant [Nm^-1]According to the question,
The new mass would be 2mThe new spring constant would be 2kso,
The new time period would be
[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{2m}{2k} } [/tex]
[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{m}{k} } [/tex]
[tex] \huge \rightarrow \: T ' \: = T[/tex]
Hence ,option B is correct ✓

explain Newtons Laws
Answers
1) Newton first law of motion: state“If a body is at rest it reamain at rest and if it is in a motion it continu its motion unless a net external force acting on it”
This law also called law of inertia
2) Newton second law of motion: states that ‟acceleration to the force acting on the body and inversky proportional to the mass of the body”
3) Newton's third law of motion: It is not possible to exert a force abody with out the body exerting a forces in the opposite direction.
These forces are called action and reaction forces

why are north and south poles important to magnets
Answers
Answer:
All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

An open pipe on an organ creates
a fundamental frequency at
10500 Hz. How long is the pipe?
Answers
Answer:
L = 1.61 cm
Explanation:
The frequency of open organ pipe is given by :
[tex]f=\dfrac{nv}{2L}[/tex]
Where
n = 1 for fundamental frequency
f = 10500 Hz
L is the length of the pipe
v is the speed of sound, v = 340 m/s
So,
[tex]L=\dfrac{nv}{2f}\\\\L=\dfrac{1\times 340}{2\times 10500 }\\\\L=0.0161\ m\\\\or\\\\L=1.61\ cm[/tex]
So, the length of the pipe is 1.61 cm.
