Answer: 1433.3 m/min
Explanation:
For 86 Km/h converted to a (m/min), convert kilometers to meters, and hour to minutes
So, 86 Km/h means 86 kilometers per 1 hour
- If 1 kilometer = 1000 metres
86 kilometers = 86 x 1000 = 86,000m
- If 1 hour = 60 minute
1 hour = 60 minutes
In m/min: (86,000m / 60 minute)
= 1433.3 m/min
Thus, 86 Km/h convert to 1433.3 m/min
Answer:
To write a number in scientific notation. First write a decimal point in the numbers so that there's only one digit to the left of the decimal point.
Answer:
The relationship between the wave's amplitude and frequency is such that it is inversely proportional to the frequency. The amplitude decreases as the frequency increases. The amplitude increases as the frequency decreases. The higher the energy of a wave, the higher the amplitude. The lower the energy, the lower the amplitude. Energy has no effect on wavelength, speed, or frequency, only the amplitude.

Answer:
Option C.
Impulse = mass × change in velocity
Explanation:
Impulse is defined by the following the following formula:
Impulse = force (F) × time (t)
Impulse = Ft
From Newton's second law of motion,
Force = change in momentum /time
Cross multiply
Force × time = change in momentum
Recall:
Impulse = Force × time
Thus,
Impulse = change in momentum
Recall:
Momentum = mass x velocity
Momentum = mv
Chang in momentum = mass × change in velocity
Change in momentum = mΔv
Thus,
Impulse = change in momentum
Impulse = mass × change in velocity
