Answer:
Explanation:
Given that,
A sphere has a volume of V and a radius r
Volume of sphere cam be determine using the formula
V = 4/3 πr³
V = 4πr³ / 3.
If the radius of the sphere is increasing by
dr / dt = 5cm / min
How fast is the volume increasing when r = 10cm
dV / dt =?
From V = 4πr³ / 3
We can calculate dV/dr
dV/dr = 12πr² / 3
dV/dr = 4πr²
Then,
We want to find dV/dt
Using chain rule
dV/dt = dV/dr × dr / dt
dV/dt = 4πr² × 5
dV/dt = 20πr²
So, at r = 10
dV/dt { 20π × 10²
dV/dt = 6283.19 cm/min
The rate at which the volume increase is 6283.19 cm/min
Answer:
co2 would be the best answer and because i just took this
Explanation:
Answer : The correct option is, (c) 
Explanation :
First we have to calculate the energy or heat.
Formula used :
where,
E = energy (in joules)
V = voltage (in volt)
I = current (in ampere)
t = time (in seconds)
Now put all the given values in the above formula, we get:
Now we have to calculate the heat capacity of the calorimeter.
Formula used :
where,
C = heat capacity of the calorimeter
= initial temperature = 
= final temperature = 
Now put all the given values in this formula, we get:
Therefore, the heat capacity of the calorimeter is,
