3.00 m^3 of water is at 20.0°C.

krok68 [10]

Answer:

9m^3

Explanation:

Given data

volume v1= 3m^3

volume v2= ???

Temperature T1= 20.0°C.

Temperature T2= 60.0°C.

Applying the relation for temperature and volume

V1/T1= V2/T2

substitute

3/20= V2/60

3*60= V2*20

180= 20*V2

180/20= V2

V2= 9m^3

Hence the final volume is 9m^3

What is sonar system ?

Pie

Sonar system is a technique that uses sound propagation for underwater activities.Sonar<span> is simply making use of an echo. When an animal or machine makes a noise, it sends sound waves into the environment around it. Those waves bounce off nearby objects, and some of them reflect back to the object that made the noise.</span>

Finger [1]

Answer:

0.652 mA

Explanation:

According to Faraday's Law :

$Emf = - \frac{d \phi}{dt}$

$= \frac{- \delta \phi }{\delta \ t}$

$|E| = \frac{A ( \delta B)}{\delta t}$

where ;

A = $8.60*10^{-4}$

$\delta B = 3.00 T - 0.5 T = 2.5 T$

$|E| = \frac{8.60*10^{-4}*2.5}{1.10}$

$|E| = 1.96*10^{-3}$

Induced current I = $\frac{|E|}{R}$

= $\frac{1.96*10^{-3}}{3.0}$

= $6.52*10^{-4} A$

= 0.652 mA

Thus, the induced current in the loop of wire over this time = 0.652 A

The distance covered is 30.2 m

Explanation:

The motion of Cynthia is a uniformly accelerated motion (constant acceleration), so we can find the distance covered by using the following suvat equation:
