Express each of the following in ms -1 a) 18kmh-1

1 answer:

3 0

1km=1000m; 1hr=3600secs
1km/hr=1000/3600= 5/18m/sec
To convert km/hr into m/sec, multiply the number by 5 and then divide it by 18.

18kmh-1= 18•5=90
90/18=5
5ms-1

The current in resistor Y is..?

Aliun [14]

(A)

Explanation:

We can see that the resistors are connected in parallel so all of them have the same voltage of 100 V. We also know that

$P = VI$

Since resistor Y dissipates 100 W of power, we can solve for the current as

$I = \dfrac{P}{V} = \dfrac{100\:\text{W}}{100\:\text{V}} = 1.0\:\text{A}$

How much heat is needed to raise the temperature of 8g of water by 15oC?

Murrr4er [49]

<h2>Answer: 502.08 J</h2>

Explanation:

The heat (thermal energy) needed in to raise the temperature in a process can be found using the following equation:

$Q=m.C.\Delta T$ (1)

Where:

$Q$ is the heat

$m=8 g$ is the mass of the element (<u>water</u> in this case)

$C$ is the specific heat capacity of the material. In the case of water is $C=4.184\frac{J}{g\°C}$

$\Delta T=15\°C$ is the variation in temperature <u>(which is increased in this case)</u>

Knowing this, let's rewrite (1) with these values:

$Q=(8 g)(4.184\frac{J}{g\°C})(15\°C)$ (2)

Finally:

$Q=502.08 J$
