What is the momentum of a baseball with a mass of 0.12 kg being thrown

Physics
1 answer:
Savatey [412]2 years ago
5 0

Answer:

5.4kgm/s towards the hitter.

Explanation:

Given parameters:

Mass  = 0.12kg

Velocity  = 45m/s

Unknown:

Momentum of the baseball  = ?

Solution:

To solve this problem, we  must understand that the momentum of a body is the quantity of motion it possesses.

 Momentum  = mass x velocity

 Now insert the parameters and solve;

 Momentum  = 0.12 x 45  = 5.4kgm/s towards the hitter.

A very good insulator has an R-value of 29. The material's heat transfer coefficient is
Fittoniya [83]

Answer:

b. 0.034

Explanation:

The heat transfer coefficient of a material (U-value) is equal to the reciprocal of its R-value, therefore:

U = \frac{1}{R}

where

R is the R-value of the material

For the insulator in this problem,

R = 29

Substituting into the equation, we find the heat transfer coefficient:

U=\frac{1}{29}=0.034

A guitarist finds that the pitch of one of her strings is slightly flat—the frequency is a bit too low. Should she increase or d
Yuri [45]

Answer:

The guitarist should increase the tension of the string.

Explanation:

The frequency of a vibrating string is determined by fn=(n/(2L))√T/μ. So if the tension in the string increased, the rate at which it vibrates (the frequency) will also increase.

Therefore it is advisable that she increase the tension of the string.
