Two blocks of aluminum (specific heat c=0.22 cal/g Celsius) with masses of 1000 g and 100 g are at a temperature of 70 c. Which
Liula [17]

Internal thermal energy is given as

Q = mCT

so it will depend on the product of mass, specific heat capacity and temperature.

so here we know that both blocks are identical with same initial temperature

So the block with larger mass must have more internal energy

So here the correct answer would be the block with mass 1000g

block with mass 1000 g must have more internal energy

When a person holds a ball above earth's surface, where is this potential energy stored?​
inn [45]

Answer:

in the ball

Explanation:

potential energy is where an object has energy, always, but it isn't always moving, and when you drop the ball, it has kinetic energy.

What was the first evidence that gravity outside our solar system worked the same way as it does inside?
Julli [10]

The first evidence that gravity outside our solar system worked the same way as it does inside is that Herschel measured the two stars that make up the Castor system moved around each other

<h3>What is a Solar system ?</h3>

The Sun, eight planets, their moons, comets, asteroids, meteoroids, and dwarf planets make up a solar system, which revolves around the Sun. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune are the eight planets that revolve in a particular order around the Sun.

  • Although there are more than 3,200 other stars in our galaxy with planets around them, our solar system is the only one that is formally referred to as a "solar system."

  • The closest stellar system to our solar system, Alpha Centauri, is one of the brightest stars in the southern skies and is only 4.3 light-years away.

Assume that the mass has been moving along its circular path for some time. You start timing its motion with a stopwatch when it
lesya692 [45]

Answer:

v = R\omega(-sin\omega t \hat i + cos\omega t \hat j)

Explanation:

As we know that the mass is revolving with constant angular speed in the circle of radius R

So we will have

\theta = \omega t

now the position vector at a given time is

r = Rcos\theta \hat i + R sin\theta \hat j

now the linear velocity is given as

v = \frac{dr}{dt}

v = (-R sin\theta \hat i + R cos\theta \hat j)\frac{d\theta}{dt}

v = R\omega(-sin\omega t \hat i + cos\omega t \hat j)
