Thermal energy quantifies the amount of heat present in the body and is calculated through the equation,
H = mcpdT
where H is the heat, m is the mass, cp is the specific heat, and dT is the temperature difference. If all things are constant, and the thermal energy is halved then, dT should also be reduced to half.
Answer:
Explanation:
Using second degree taylor polynomials
let
be position function and set ![S(0)=0](https://tex.z-dn.net/?f=S%280%29%3D0)
where S(0) is the initial position
Then
and ![a(t)=S^{ii}(t)](https://tex.z-dn.net/?f=a%28t%29%3DS%5E%7Bii%7D%28t%29)
we have
, ![a(0) = 4m/s^2](https://tex.z-dn.net/?f=a%280%29%20%3D%204m%2Fs%5E2)
so ![T_{2}(t) =S(0)+v(0)t+\frac{a(0)}{2} t^2\\\\\\=0+60t+\frac{4}{2} t^2\\\\T_{2}(t)=60t+2t^2\\\\S(1)=T_{2}(1)=60+2=62m](https://tex.z-dn.net/?f=T_%7B2%7D%28t%29%20%3DS%280%29%2Bv%280%29t%2B%5Cfrac%7Ba%280%29%7D%7B2%7D%20t%5E2%5C%5C%5C%5C%5C%5C%3D0%2B60t%2B%5Cfrac%7B4%7D%7B2%7D%20t%5E2%5C%5C%5C%5CT_%7B2%7D%28t%29%3D60t%2B2t%5E2%5C%5C%5C%5CS%281%29%3DT_%7B2%7D%281%29%3D60%2B2%3D62m)

I think it is a parabola.
Answer:
![i = 4.9 A](https://tex.z-dn.net/?f=i%20%3D%204.9%20A)
Explanation:
Force on a current carrying rod due to magnetic field is given as
![F = iLB](https://tex.z-dn.net/?f=F%20%3D%20iLB)
here we know that
current in the rod
![B = 0.10 T](https://tex.z-dn.net/?f=B%20%3D%200.10%20T)
![L = 1.0 m](https://tex.z-dn.net/?f=L%20%3D%201.0%20m)
now magnetic force is balanced by the weight of the rod
so we will have
![iLB = mg](https://tex.z-dn.net/?f=iLB%20%3D%20mg)
![i(1.0)(0.10) = 0.05 \times 9.8](https://tex.z-dn.net/?f=i%281.0%29%280.10%29%20%3D%200.05%20%5Ctimes%209.8)
![i = 4.9 A](https://tex.z-dn.net/?f=i%20%3D%204.9%20A)
