Answer:

Heat Capacity = E / T.

- Find the difference in temperature for changes of multiple degrees.

- Add the appropriate units to your answer to give it meaning.

- Know that this equation works for cooling objects as well.

- Know that specific heat refers to the energy needed to raise one gram by one degree.

How many hydrogen atoms are found in two molecules of hydroxylamine, 2NH2OH?

Bogdan [553]

It would be six because in every one molecule, there are three atoms of hydrogen, so just double that and you have six.

Force F=2.0N i - 3.0N k acts on a pebble with position vectorr=0.50m j - 2.0m k relative to the origin. In unit vector notation,

klasskru [66]

Answer with Explanation:

We are given that

Force acts on a pebble= $2\hat{i}-3\hat{k}$ N

Position vector= $r=0.5\hat{j}-2\hat{k}$ m

a.We have to find the resulting torque on the pebble about origin.

Torque= $r\times F$

Substitute the values then we get

$Torque= (0.5j-2k)\times (2i-3k)$

Torque= $-k-1.5i-4j$ N-m

By using $i\times j=k,j\times k=i,k\times i=j,j\times i=-k,k\times j=-i,i\times k=-j,i\times i=j\times j=k\times k=0$

b. $r=2i-3k$

$r-r_1=(0.5j-2k)-(2i-3k)=-2i+0.5j+k$

Torque about point (2,0,-3)

$\tau=(-2i+0.5j+k)\times (2i-3k)$

$\tau=-6j-k-1.5i+2j=-1.5i-4j-k$ N-m

Explanation:

Let the required velocity of rocket be v .

We shall use the formula of time dilation to find the velocity of rocket .

t = $\frac{t'}{\sqrt{1-\frac{v^2}{c^2} } }$

t = 430

t' = 38

$430=\frac{38}{\sqrt{1-\frac{v^2}{c^2} } }$

$\sqrt{1-\frac{v^2}{c^2} } }=\frac{38}{430}$

$1-\frac{v^2}{c^2}$ = .0078

$\frac{v^2}{c^2}$ =.9922

$\frac{v}{c}$ = .996

v = .996 x 3 x 10⁸ m /s

= 2.988 x 10⁸ m /s

B )

Kinetic energy of rocket

= 1/2 m v²

= .5 x 20000 x (2.988 x 10⁸ )²

= 8.9 x 10²⁰ J .

C )

This energy is 8.9 times the energy requirement of United states in the year 2005 .
