Two pop cans are at rest on a stand. A firecracker is placed between the cans and lit. The firecracker explodes and exerts equal

and opposite forces on the two cans. Assuming the system of two cans to be isolated, the post-explosion momentum of the system ____.
a. is dependent upon the mass and velocities of the two cans
b. is dependent upon the velocities of the two cans (but not their mass)
c. is typically a very large value
d. can be a positive, negative or zero value
e. is definitely zero

Answer:

e. is definitely zero

Explanation:

Given that

At initial condition the speed of the pop cans is zero.

We know that linear momentum

P = Mass x velocity

P =  m v

At initial condition v = 0

P= 0

If there is no any external force then the linear momentum of the system will be conserve.And given that ,consider the system isolated.

Therefore the answer is e.

Why is everything spinning? Moons, planets and stars all rotate on their axes, moons orbit planets, planets orbit stars, spiral
kow [346]

Answer:

Conservation of angular momentum

Explanation:

When the objects spread in universe after big bang, because of the tremendous force , they gained angular momentum and started to rotate. Since, then the object continue to rotate on their axis because of conservation of angular momentum. In vacuum of space there no other forces that can stop these rotation, therefore, they continue to rotate.

How long does it took for 1000-watt microwave oven to do 20000 joules of work
svp [43]

Answer:

20 seconds

Explanation:

The equation for Power is:

Power = \frac{Work}{time}

Which means...

Time=\frac{Work}{Power}

We can plug in the given values into the equation:

Time = \frac{20000\ J}{1000\ W}

Time=20 \ s

Which statements accurately describe the shape of Earth’s orbit around the Sun? Check all that apply.
damaskus [11]
<span>The Earth’s orbit is a nearly circular ellipse.
</span><span>The Sun is located at one of the two focal points.</span>

The Earth moves around the Sun in an orbit that is almost but not quite circular. As Kepler proved in the seventeenth century, the orbit is actually an ellipse. A parameter called the eccentricity (e) defines the degree of departure from a circle. A value of e=0 would indicate a circle whereas a value of e=0.9 would indicate a very elongated ellipse. The eccentricity of the Earth's orbit is currently e=0.0167.
