Answer: Beta, alpha and gamma ray
Explanation: The component being deflected to the positive side is the beta radiation because it is negatively charged and thus is attracted by the positive terminal of the Electric Field.
The component being deflected to the negative side is the alpha radiation, it's is positively charged and thus being attracted by the negative part of the Electric Field.
The component that went straight down without deflection is the gamma radiation. It is neutral and possess no charge and thus is not deflected.
Answer:
the amount of heat that gets through both the wires will be same.
Explanation:
By the Fourier's law of conduction we have:

where:
= rate of heat transfer
k = thermal conductivity of the material
A = area of the material
dT = temperature difference across the length dx
According to the question, the system to be analysed is isolated from the surrounding.
Until the thermal equilibrium is established between aluminium and copper wires the amount of heat that gets through both the wires will be same.
<em>But the rate of heat transfer through the aluminium will be greater as it has double the thermal conductivity of copper.</em>
Answer:
Because nuclear decay releases ionizing radiation (alpha, beta, and gamma radiation) we call such compounds radioactive.
Explanation:
I think it would be plum pudding, solid ball, solar system.
Answer:
496.57492 kg/m³
Explanation:
= Atmospheric pressure = 101300 Pa
= Density of water = 1000 kg/m^3
= Height of water = 21.8 cm
= Height of fluid = 30 cm
g = Acceleration due to gravity = 9.81 m/s²
= Density of the unknown fluid
Absolute pressure at the bottom

The density of the unknown fluid is 496.57492 kg/m³
