The cloud chamber, the Geiger counter, and a piece of
photographic film can all reveal the presence of radioactivity. 
Batteries don't.

Answer: Battery

Explanation:

A battery is a source of energy. A battery stores energy in the form of chemical energy and when placed in the circuit, the chemical energy converts to electrical energy. Thus, it is not used to detect radioactivity.

Cloud chamber, Geiger counter  and photographic film are used to detect radioactivity.  A Geiger counter consists of tube filled with gas which gets ionized from radioactive decay. The ionized gas produces electric current which is detected and measured. Photographic film is a photo-sensitive strip which used to detect radiations. Cloud chamber is a particle detector and their trajectories.

Conservation of Momentum Practice
Yakvenalex [24]

Answer:

Before: 0 m/s  

After: -4 m/s

Explanation:

Before: Since you and your beau started at rest, your beau initial velocity is 0 m/s.

After: Since we have to conserve momentum,

momentum before push = momentum after push.

The momentum before push = 0 (since you and your beau are at rest)

momentum after push = m₁v₁ + m₂v₂ were m₁ = your mass = 60 kg, v₁ = your velocity after push = 3 m/s, m₂ = beau's mass = 45 kg and v₂ = beau's velocity.

So, m₁v₁ + m₂v₂ = 0

m₁v₁ = -m₂v₂

v₂ = -m₁v₁/m₂ = -60 kg × 3 m/s ÷ 45 kg = -4 m/s

So beau moves with a velocity of 4 m/s in the opposite direction

A particle is moving in a circular path of radius r . The displacement after half a circle would be
Art [367]

Answer:

2r

Explanation:

As we know that

The displacement is the total distance measured between the initial or start and final or destination point

If particle cover half path of the circle, the displacement can easily find out by considering the distance between the start and destination point

We attached the diagram for better understanding

As per the diagram.

The displacement after half-circle is

AB = OA + OB

= r + r

= 2r

5. Calculate the speed of Charlie who runs to the store 5 kilometers away in 40<br> minutes
exis [7]
This depends on what units you need to convert to, but the answer would be approximately 2.083 m/s.

5km/40min = 5000m/40min = 5000m/2400s = 2.083 m/s
