Answer:
brighter
Explanation:
the more light bulbs you add to a series of circuits, the brighter the room will be.
The current is defined as the amount of charge transferred through a certain point in a certain time interval:

where
I is the current
Q is the charge

is the time interval
For the lightning bolt in our problem, Q=6.0 C and

, so the average current during the event is
Answer:
The heat capacity of a sample is 37.7 J/K.
Explanation:
Given that,
Submerged temperature of tissue sample = 275 K
Mass of liquid nitrogen= 2 kg
Temperature = 70 K
Final temperature = 75 K
We need to calculate the heat
Using formula of heat

Put the value into the formula


We need to calculate the heat capacity of a sample
Using formula of heat capacity

Put the value into the formula


Hence, The heat capacity of a sample is 37.7 J/K.
