g You are blowing air into a spherical balloon at a rate of 33 cubic inches per second. Given that the radius of the balloon is

Marina CMI [18]

Answer:

$\frac{3}{16\pi}in/sec$

Explanation:

We are given that

$\frac{dv}{dt}=3in^3/s$

r=2 in when t=4 s

We have to find the rate of change of radius.

We know that

Volume of sphere= $V=\frac{4}{3}\pi r^3$

Differentiate w.r.t t

$\frac{dV}{dt}=4\pi r^2\frac{dr}{dt}$

Substitute the values

$3=4\pi(2)^2\times \frac{dr}{dt}$

$\frac{dr}{dt}=\frac{3}{4\pi(2)^2}$

$\frac{dr}{dt}=\frac{3}{16\pi}in/sec$

if a 3.1g ring is heated using 10.0 calories, its temperatures rises 17.9C calculate the specific heat capacity of the ring

Aleksandr-060686 [28]

So what you do is you use the formula shown below:

specific heat capacity = energy required / (mass * change in temperature)

here ,
energy required = 10.0°C Note that cal. is short form for °C
mass (m) = 3.1g
change in temperature (ΔT) = 17.9°C Note that "ΔT" means change in temperature

So, plugging the values into the formula, we get,

Specific heat capacity= $\frac{10}{3.1*17.9}$

= $0.1802126509$

= 0.1802 cal./g°C <span>i rounded the answer to the fourth decimal point
