Alpha radiation consists of fast-moving helium particles, and Beta radiation consists of electrons. Although helium particles are tiny, and electrons even tinier, these still consistent matter. Alpha and Beta waves consist of matter.
Gamma radiation consists of pure energy in the form of electromagnetic rays, and therefore do not consist of matter.
The answer is A) It does not consist of matter
Answer:
a spinning top
thats the answer and I hope it helps
Answer:
C. C
Explanation:
A wave can be defined as a disturbance in a medium that progressively transports energy from a source location to another location without the transportation of matter.
In Science, there are two (2) types of wave and these include;
I. <u>Electromagnetic waves</u>: it doesn't require a medium for its propagation and as such can travel through an empty space or vacuum. An example of an electromagnetic wave is light.
II. <u>Mechanical waves</u>: it requires a medium for its propagation and as such can't travel through an empty space or vacuum. An example of a mechanical wave is sound.
A crest can be defined as the highest (vertically) point on a waveform.
On a related note, a trough is the lowest (vertically) on a waveform.
An amplitude can be defined as a waveform that's measured from the center line (its origin or equilibrium position) to the bottom of a trough or top of a crest. Thus, the vertical axis (y-axis) is the amplitude of a waveform i.e it's measured vertically.
In this scenario, waveform C which is represented by a blue curvy line has the smallest amplitude in comparison with the other waveforms because it has the minimum height when measured from the origin.
In contrast, waveform A represented by a purple line has the highest amplitude because it has the maximum height when measured from the origin.
Mathematically, the amplitude of a wave is given by the formula;
x = Asin(ωt + ϕ)
<u>Where;</u>
- <em>x is displacement of the wave measured in meters.</em>
- <em>A is the amplitude.</em>
- <em>ω is the angular frequency measured in rad/s.</em>
- <em>t is the time period measured in seconds.</em>
- <em>ϕ is the phase angle.</em>
Answer:
a)
b)
Explanation:
From the question we are told that
Diameter of hole 
Depth of hole 
Diameter of tank 
Generally the equation for pressure is mathematically given as
Where
Generally the level at which the water level will initially drop if the water is not replenished is mathematically given by
Therefore the level at which the water level will initially drop if the water is not replenished
Refer to the diagram shown below.
The net force acting on the vehicle is
F - R = 1060 -1010 = 50 N
The distance traveled is 21 m. Because the force is constant, the work done is
W = (50 N)*(21 m) = 1050 J
Assume that energy is not dissipated by air resistance or otherwise.
Conservation of energy requires that W = KE, where KE is the kinetic energy of the vehicle.
The KE is
KE = (1/2)*(2000 kg)*(v m/s)² = 1000v² J
Equate KE and W to obtain
1000v² = 1050
v² = 1.05
v = 1.025 m/s
Answer: 1.025 m/s
