Explain the difference in polarity between co2 and h2o by referring to the polarity of the bonds and the shape of the molecules

2 answers:

Both H2O and CO2 have polar covalent bondings (O is more electronegative than H or C) . The main molecular difference arises from their different geometry.

CO2 is a linear molecule so despite of having to dipolar bonds they add up and exactly cancel each other rendering the molecule non-polar.

Answer:

The net force is 21 N, and the bag will go to the right.

Explanation:

You can find the net force by adding both values of the boy and the girl, and then subtracting four from it. You can also figure out which direction its moving by looking at which side is exerting the most force, which would be the right side.

Hope it helps!

A light bulb is rated at 25 W when operated at 120 V. How much charge enters (and leaves) the light bulb in 1. 0 min?

aleksklad [387]

The amount of charge enters (and leaves) is 12 Coulomb.

<h3 /><h3>How can we find the value of the amount of charge enters (and leaves)?</h3>

Here we are using the formula,

$I=\frac{P}{V}$ and $Q= I \times t$

We are given,

P = Power of the light bulb = 25 Watt.

V = The amount of voltage where the light bulb operated = 120 Volt.

t= The time when charge enters (and leaves) the light bulb = 1.0 min = $(1 \times 60) second$ = 60 S

We have to find,

I= The amount of current flows in the light bulb.

Q= The amount of charge enters (and leaves) the light bulb.

Now we substitute the values of known parameters in the first equation, we find that,

$I=\frac{P}{V}=\frac{25}{120}$

Or, $I= 0.20 A$

The amount of current flows in the light bulb is 0.20 Ampere.

Now, we put the value of I in the second equation,

$Q= I \times t= 0.20 \times 60$

Or, $Q=12 C$

So, from the above calculations we can see that the amount of charge enters (and leaves) the light bulb is 12 Coulomb.

Plzzzz urgent solve this

Answer:

$\large{ \tt{☄ \: EXPLANATION}} :$

Before solving , You'll have to know - When an object starts from the state of rest , in this case , initial velocity ( u ) = 0

Notice that we're provided the time ( t ) in minutes. So , first thing we have to do is convert the minutes into seconds. It would be - Time ( t ) = 5 minutes = 5 × 60 sec = 300 sec [ 1 min = 60 sec ]

Here , We're provided - Initial velocity ( u ) = 0 , Final velocity ( v ) = 60 m / s , Time taken ( t ) = 300 seconds & We're asked to find out the acceleration ( a ) & distance covered by the jeep ( s ) .
