F = ma so u can plug in the given numbers and solve:
F = (2)(3)
Answer:
The distance travelled on the freeway is 149.5 miles.
Explanation:
The school bus travels on the freeway at constant speed. According to the statement, we need to calculate the distance travelled by the vehicle by means of the following formula:
(1)
Where:
- Traveled distance, in miles.
- Speed, in miles per hour.
- Time, in hours.
If we know that
and
, then the distance travelled by the school bus is:



The distance travelled on the freeway is 149.5 miles.
Answer:
The time elapses until the boat is first at the trough of a wave is 4.46 seconds.
Explanation:
Speed of the wave, v = 59 km/h = 16.38 m/s
Wavelength of the wave, 
If f is the frequency of the wave. The frequency of a wave is given by :

The time period of the wave is given by :

We need to find the time elapses until the boat is first at the trough of a wave. So, the time will be half of the time period of the wave.

Hence, this is the required solution.
Answer:
discrimination: prejudice towards a person/group based on their race, sex, age, and/or sexual orientation
Explanation:
People of color face discrimination because of the color of their skin.
We know, length of segment wave is half the wavelength .
Let, wavelength of wave is
.
So, length of segment will be
.
Now, it is given that the string vibrates in four segments.
So,

Speed can be given by :

Therefore, the wave speed in the string is 120 m/s.
