Low velocity im pretty sure
Answer:
<em>15 cm</em>
<em></em>
Explanation:
Displacement is the shortest distance between the point of origin of a body in motion to the final stopping positing.
For this ant's aunt's aunt that travels from the 15.00 cm mark to the 85.00 cm mark back to the 30.00 cm mark and then finally to the 30.00 cm mark, the displacement from the starting position is..
displacement = stopping point - starting point
d = 30 cm - 15 cm = <em>15 cm</em>
Answer:
37.5 Seconds
Explanation:
Speed = frequency * Wavelength
We can find the Frequency by the information given, Frequency = waves per second .
40 Waves per second, = 40 Hz
Wavelength = 8cm
Cm = M
8cm/100 = 0.08m
Speed = 40 Hz * 0.08m
Speed = 3.2m/s
Speed = Distance / time taken
Time = Distance / Speed
Time = 120 / 3.2
Time = 37.5 seconds
The acceleration of the bike is
Explanation:
We can solve this problem by using Newton's second law of motion, which states that:
where
F is the net force on an object
m is the mass of the object
a is its acceleration
For the bike in this problem, we have
F = 175 N is the net force
m = 50 kg is the mass
And solving for a, we find the acceleration:

Answer:
0.000000002 m=2.0*10⁻⁹ m
Explanation:
Scientific notation allows us to write very large or very small numbers in abbreviated form. This notation simply consists of multiplying by a power of base 10 with a positive or negative exponent.
A number written in scientific notation has the form:
a*10ⁿ
where:
- the coefficient a has a value such that 1 ≤ a <10
- n is an integer. Represents the number of times the decimal point is shifted. It is always a whole number, positive if it is shifted to the left, negative if it is shifted to the right.
So to write the number 0.000000002 in scientific notation, the following steps are performed:
- The decimal point is moved to the right as many spaces until it reaches the right of the first digit.
- This number is then written, which will be the coefficient a in the expression of the previous product. So a=2.0
- The base 10 is written with the exponent equal to the number of spaces that the comma moves. So n=9. But this is a negative number because the comma shifts to the right.
So, you get: <u><em>0.000000002 m=2.0*10⁻⁹ m</em></u>
