insens350 [35]3 years ago
7 0

Answer:

0.31s

Explanation:

Given parameters:

Frequency of the ocean waves  = 3.2Hz

Unknown:

Period of the waves  = ?

Solution:

The period of a wave is the inverse of the frequency of a wave;

       Period  = \frac{1}{Frequency}

Now insert the parameters and solve;

       Period  = \frac{1}{3.2}   = 0.31s

As light shines from air to water (n = 1.33) at an incident angle of 45.0 degrees what is the angle of refraction
erma4kov [3.2K]
Using Snell's law
we get
sin(I)/sin(r) = U2/U1
• where U2 represent the water's refractive index and U1 represent air's refractive index
thus
sin45°sin(r) = 1.33/1
1/√2*1.33 = sin(r)
1/1.88 = sin(r)
0.531 = sin(r)
thus the refractive angle is 32°

A 0.80 kg basketball traveling upward at 5.0 m/s impacts an 8.0 10 kg tennis ball traveling downward at 5.0 m/s. The basketball’
vlabodo [156]

To solve this problem we will apply the concepts related to the conservation of momentum. This can be defined as the product between the mass and the velocity of each object, and by conservation it will be understood that the amount of the initial momentum is equal to the amount of the final momentum. By the law of conservation of momentum,

m_1u_1+m_2u_2 = m_1v_1+m_2v_2

Here,

m_1 = Mass of Basketball

m_2 = Mass of Tennis ball

u_1 = Initial velocity of Basketball

u_2 = Initial Velocity of Tennis ball

v_1 = Final velocity of Basketball

v_2 = Final velocity of the tennis ball

Replacing,

(0.8)(0.5)+(0.1)(-5.0)=(0.8)(0.3)+(0.1)v_2

Solving for the final velocity of the tennis ball

v_2 = 11m/s^2

Therefore the velocity of the tennis ball after collision is 11 m/s
