Answer:
Explanation:
Given the following :
Speed (V) = speed of 2.30×10^7 m/s
Acceleration (a) = 1.70×10^13 m/s^2
Using the right hand rule provided by Lorentz law:
B = F / qvSinΘ
Where B = magnitude of the magnetic field
v = speed of the particle
Θ = 90° (perpendicular to the field)
q = charge of the particle
SinΘ = sin90° = 1
Note F = ma
Therefore,
B = ma / qvSinΘ
Mass of proton = 1.67 × 10^-27
Charge = 1.6 × 10^-19 C
B = [(1.67 × 10^-27) × (1.70 × 10^13)] / (1.6 × 10^-19) × (2.30 × 10^7) × 1
B = 2.839 × 10^-14 / 3.68 × 10^-12
B = 0.7715 × 10^-2
B = 7.72 × 10^-3 T
2) Magnetic field will be in the negative y direction according to the right hand thumb rule.
Since Velocity is in the positive z- direction, acceleration in the positive x - direction, then magnetic field must be in the negative y-direction.
Answer:
24 kgm/s
Explanation:
Momentum (p) = mass x velocity
Mass = 3kg , velocity 8m/s
momentum (p) = 3kg x 8m/s
= 24kgm/s
Answer:
Explanation:
The main reason for doing this is to get the attention of the tertiary institutions early. There are thousands of students that apply to these institutions every year, depending on the strictness of the acceptance of these institutions it may or may not be difficult for you to enter. Applying while at grade 11 gives you more chances of getting in as you are catching the attention of the institution and showing a high level of interest. This also allows you more chances to enter, since if you are denied you can try again next year. Aside from this, some institutions have specific requirements, applying early can allow you to know what you are missing as they will tell you if you get denied. You can then work towards obtaining these requirements and apply next year.
Explanation:
In this case, it is required to match the following terms with their definitions.
1. Amplitude : the maximum displacement of particles (positive or negative) during wave motion.
2. Crest : the high point of a wave.
3. Frequency : The number of oscillations that occur in a given time period.
4. Hertz : the unit for the frequency of a wave; the number of waves per second.
5. Period : the time required for one wavelength to pass.
6. Stiffness : degree to which a medium resists being compressed.
7. Trough : the low point of a wave.
The above parameters are the characteristics of a wave. A wave is defined by the above parameters. Hence, this is the required solution.
