A baseball bat balances 74.9 cm from one end. If an 0.560-kg glove is attached to that end, the balance point moves 25.3 cm towa

timurjin [86]

Answer:

The mass of the bat is 1.09 kg.

Explanation:

Given that,

The balance point of the glove, x = 74.9 cm

Mass of the glove, m = 0.56 kg

Center of mass of the baseball bat, C = 25.3 cm

Let M is the mass of the bat. The center of mass is given by the formula as :

$C=\dfrac{MX+mx}{M+m}$

X is 0 as it is at a end

$C=\dfrac{mx}{M+m}$

$25.3=\dfrac{0.56\times 74.9}{M+0.56}$

M = 1.09 kg

So, the mass of the bat is 1.09 kg. Hence, this is the required solution.

A viola string with a fundamental frequency of D4 (293 Hz) is generally tuned using a tension of 49.0 N. However, just before a

Alborosie

Answer:

Explanation:

For fundamental frequency in a vibrating string , the formula is

n = 1 / 2L x √ ( T /m₁ )

n is frequency , L is length , T is tension and m₁ is mass per unit length .

For first string ,

293 = 1 / 2L x √ ( 49 N /m₁ )

For second string , let mass per unit length be m₂ .

196 = 1 / 2L x √ ( 49 N /m₂ ) ------ ( 1 )

To bring its frequency back to previous one let tension be T

293 = 1 / 2L x √ ( T /m₂ ) ------- ( 2 )

Dividing

293 / 196 = √ ( T /49 )

1.4948 = √ ( T /49 )

2.2344 = T /49

T = 109.48 N .
