Answer:
A stripe of magnetic information that is affixed to the back of a plastic credit or debit card.
Answer:25000/23 N/M^2
Explanation:
P=f/A=30/(0.23×0.12)=25000/23
The acceleration that Andrew experience during his ride is 3.6m/s²
The formula for calculating centripetal acceleration is expressed as:
a = v²/r
v is the speed
r is the radius
Given the following expression
v = 6m/s
r = 10m
Substitute the given parameters into the formula
a = 6²/10
a = 36/10
a = 3.6m/s²
Hence the acceleration that Andrew experience during his ride is 3.6m/s²

Answer;
= 4 m is the length of the man's shadow.
Explanation;
2/x=6/(8+x) cross multiply.
6x=2(8+x)
6x=16+2x
6x-2x=16
4x=16
x=2=16/4
x=4 m. is the length of the man's shadow.
Answer: choices a and b
Explanation:
Telescope can be defined as am optical instrument which is designed to observe the distant objects clear and nearer. It comprises of arrangement of lenses which allow the rays of light to be collected. The collected light is focused and the image so produced is magnified in the form of an image. The telescopes are prepared and manufactured on mountains top as this will help in preventing the distortion of light obtain from the star due to the fluctuation of air mass in the atmosphere. The atmospheric distortion affects the resolution, and affects the vision. The atmospheric pressure is low at the mountain tops so it will help in better observation of the sky.
