A bat hits a moving baseball. If the bat delivers a net eastward impulse of 0.80 N-s and the ball starts with an initial horizon
AURORKA [14]

Answer:

0.084 kg

Explanation:

I = 0.80 N-s (East wards) = 0.80 i N-s

u = 3.8 m/s = - 3.8 i m/s

v = 5.7 m/s = 5.7 i m/s

Let m be the mass of bat.

I = m (v - u)

0.8 i = m ( 5.7 i + 3.8 i)

0.8 i = m x 9.5 i

m = 0.084 kg

The percentage of water vapor in the air compared to the maximum amount of water vapor that air can contain at a particular temp
natali 33 [55]

Answer:

Relative humidity %

Explanation:

  • The relative humidity is the percentage of the water vapor content at a particular temperature and pressure to the maximum amount of water vapor content the air can hold at those conditions.
  • When the relative humidity of the air becomes 100% then there occurs precipitation on the earth from the atmosphere (specifically troposphere, which accounts for the weather changes).
  • We might have experienced excessive sweating even on a relatively less hotter day of a summer which is on account of increased relative humidity.

In certain ranges of a piano keyboard, more than one string is tuned to the same note to provide extra loudness. For example, th
diamong [38]

Answer:

3.77 Hz

Explanation:

The beat frequency that is heard can be calculated using the following equation:

f_{b} = f_{1} - f_{2}

<u>Where:</u>

f₁ = 110 Hz

f_{2} = \frac{f_{1}}{\sqrt{\frac{T_{1}}{T_{2}}}}

<u>With:</u>

<em>T₁ = 594 N        </em>

<em>T₂ = 554 N </em>

f_{2} = \frac{f_{1}}{\sqrt{\frac{T_{1}}{T_{2}}}} = \frac{110 Hz}{\sqrt{\frac{594 N}{554 N}}} = 106.23 Hz

Hence, the beat frequency is:        

f_{b} = f_{1} - f_{2} = 110 Hz - 106.23 Hz = 3.77 Hz      

Therefore, the beat frequency that is heard when the hammer strikes the two strings simultaneously is 3.77 Hz.

I hope it helps you!
