We can't look at Figure 4. We don't know where a and b are. We can't see the blue shaded area. We don't know what our method above was. We can't see the green skinny rectangle.
Answer:
Vector Quantity: A physical quantity is said to be a vector quantity when it has both magnitude and direction. The scalar quantities are distance, mass, time, volume, density, speed, temperature, and energy, The vector quantities are weight, velocity, acceleration, and force.
Explanation:
Mark me brainleist PLZZZZ
-- Volume . . . made out of 3 dimensions of length
-- Density . . . made out of mass, and 3 dimensions of length
-- Area . . . made out of 2 dimensions of length
-- Acceleration . . . made out of length and time
<em>Mass</em> is not made out of anything else. It's fundamental. A few other fundamental things are length, time, and electric charge.
If the jars are all the same size, and there's the same AMOUNT of liquid in
each jar, then the most dense liquid is the one that's in the heaviest jar.
A)
Q=606 J
<span> W = 418 J
</span><span> From first law of thermodynamics,
</span><span> [ Uf - Ui ] = Q - W
</span><span> [ Uf - Ui ]=606 -418=188 J
</span><span> [ Uf - Ui ]= 188 J
</span><span>
b )
W2 = 1212 J
</span><span> Q2 = ?
</span><span> Ui2=Uf =Ui +188
</span><span> Uf2=Ui
</span> [ Uf2 - Ui2 ]<span>=Ui-(Ui+188)
</span><span> -188 J
</span><span> Q2=W2+(Uf2 -Uf1)
</span><span> Q2 =1212 -188=1024 J
</span><span> Q added in second step (b) so that internal energy is equal to initial internal energy of step (a)=1024 J</span>
