Answer:
The SI units of A, B and C are :
[tex]m,\ m/s\ and\ m/s^2[/tex]
Explanation:
The position x, in meters, of an object is given by the equation:
[tex]x=A+Bt+Ct^2[/tex]
Where
t is time in seconds
We know that the unit of x is meters, such that the units of A, Bt and [tex]Ct^2[/tex] must be meters. So,
- [tex]A=m[/tex]
- [tex]bt=m[/tex]
[tex]b=\dfrac{m}{s}=m/s[/tex]
- [tex]Ct^2=m[/tex]
[tex]C=m/s^2[/tex]
So, the SI units of A, B and C are :
[tex]m,\ m/s\ and\ m/s^2[/tex]
So, the correct option is (B).
The SI units of A, B, and C is option B [tex]m, m/s, m/s^2[/tex]
- The calculation is as follows;
The position x, in meters, of an object is provided by the equation:
[tex]x = A + Bt + Ct^2[/tex]
Here
t should be t in seconds
As We know that the unit of x should be in meters, in such a way that the units of A, Bt and must be meters.
So,
A = m
bt = m
[tex]b = m\div s = m/s\\\\ Ct^2 = m\\\\ C = m/s^2[/tex]
