Answer:
speed are different at different places
Explanation:
because it's top speed is 50km/h,so it's initial speed may be less. when it covers some distance it's speed changes again. then we have given a mean speed .mean speed means sum of all speed divided by sum of total time.so the mean speed and final speed differs from each other
The rows of the table called periods had eight elements with atomic mass left to right it was a good model cause u can predict to know elements and properties hope this helped
Answer:
356.33 J
Explanation:
Energy: This can be defined as the ability or the capacity to do work. The S.I unit of Energy is Joules (J).
The Energy stored in a capacitor = 1/2CV²
E = 1/2CV².............................. Equation 1.
Where E = Energy stored in a capacitor, C = capacitance of the capacitor, V = potential difference across the plates of the capacitor.
Given: C = 10.5 μF = 10.5×10⁻⁶ F, V = 8250 V.
Substitute into equation 1
E = 1/2(10.5×10⁻⁶)(8250)²
E = 357.33 J.
Thus the energy stored in the defibrillator = 356.33 J
