The correct answer to the question is : 
EXPLANATION :
As per the question, the specific heat of gold is given as c = 
The heat given to the gold dQ = 195 J
The mass of the gold is given as m = 15 gram.
We are asked to calculate the change in temperature.
Let the change in temperature is dT.
We know that dQ = mcdT

[ANS]
Hence, the change in temperature is 100 degree celsius.
Answer:
4.8 watts
Explanation:
power = voltage * current = 12.0 * 0.40 = 4.8 watts
Answer:
Glucose - from the food we eat, then the food is broken down into another type of sugar called glucose.
Amino Acid - animal proteins such as meat, eggs and poultry. When you eat protein, it is broken down into amino acids.
Oxygen - we get oxygen by breathing in fresh air.
Answer: part a: 19.62m
part b: 19.62 m/s
part a: 2.83 secs
Explanation:If the air resistance is ignored then the swimmer experience free fall under gravity hence
u=0
a=9.81 m/s2
t=2 secs

s=h

Part b

Part c
now we have h=2*19.62=39.24
