300/8 = 37.5
37.5 x 12 = 450
New temp. = 450 K
Hope this helps!

Why don't the present shapes of the continents fit perfectly into the supercontinent?
kirza4 [7]
<span>The reason why the shapes of the continents as of today do not perfectly fi into to super continent because long time ago the super continent was scattered into pieces. And as times go by, those smaller parts of super continents undergo soil erosion caused by the water and other way that causes their original shapes change.  
Thus, if we are going to judge now if those smaller part of super continent, they’re no longer gonna fit perfectly because through time their original form changed</span>

A piano wire with mass 2.60g and length 84.0 cm is stretched with a tension of 25.0 N. A wave with frequency 120.0 Hz and amplit
likoan [24]

Answer:

Power will be 0.2023 watt

And when amplitude is halved then power will be 0.0505 watt

Explanation:

We have given mass of the Piano wire m = 2.60 gram = 0.0026 kg

Length of wire l = 84 cm = 0.84 m

So mass density \mu =\frac{m}{l}=\frac{0.0026}{0.84}=0.0031kg/m

Tension in the wire T = 25 N

Frequency f = 120 Hz

So angular frequency \omega =2\pi f=2\times 3.14\times 120=753.6rad/sec

And amplitude A = 1.6 mm = 0.0016 m

We have to find the generated power

Power is given by P=\frac{1}{2}\sqrt{\mu T}\omega ^2A^2=\frac{1}{2}\times \sqrt{0.0031\times 25}\times 753.6^2\times 0.0016^2=0.2023watt

From the relation we can see that power P\ \propto\ A^2

So if amplitude is halved then power will be \frac{1}{4} times

So power will be equal to \frac{0.2023}{2}=0.0505watt

A plastic rod that has been charged to -21 nc touches a metal sphere. afterward, the rod's charge is -8 nc. (a) what kind of cha
otez555 [7]
The rod transferred negatively charged particle to the metal sphere. The rod becomes less negatively charged than it was originally (originally it was charged to -21 nc, now it has -8, and -8>-21), so it must have moved 13 nc of negative charge to the sphere.

A spaceship travels at a constant speed from earth to a planet orbiting another star. When the spacecraft arrives, 12 years have
tigry1 [53]

Answer:

7.2878\times10^{16} m

Explanation:

Time elapsed on Earth d_{t}= 12 years

Time elapsed on board the shipd_{t_o} = 9.2 years

now r= \frac{d_{t} }{d_t_o}= 12/9.2= 1.3043

v= c \sqrt{1-\frac{1}{r^2}}

v= 3\times10^8 \sqrt{1-\frac{1}{1.3043^2}}

v= 1.9258\times10^8

therefore distance L=  d_{t}\times v

putting value we get

=12\times\times1.9258\times10^8

=12\times\times365\times24\times3600\times1.9258\times10^8

= 7.2878\times10^{16} m
