Given that,
Acceleration due to gravity = g
Time period :
Time period is defined as,

Where, l = length of pendulum
g = acceleration due to gravity
We need to calculate the value of g
Using formula of time period


Where, T = time period
l = length of pendulum
Hence, The value of g is 
Answer:
692 J/kg/°C
Explanation:
Electric energy added = amount of heat
Power × time = mass × SHC × increase in temperature
Pt = mCΔT
(15 V × 3 A) (10 min × 60 s/min) = (0.6 kg) C (85°C − 20°C)
C = 692 J/kg/°C
The law looks at the forces created between two charged objects. As distance increases, the forces and electric fields decrease. Positive and negative charges like to move towards each other. Similar charges such as two positive or two negative push away from each other.
