Answer:
if the frequency of the wave if tripled then period of wave gets tripled
Answer:
P=160000Pa
Explanation:
You haven't specified what to calculate
But looking at the parameters I think the question is asking to calculate the pressure exerted.
Pressure=Force/Area
P=40000/0.25m²
P=160000Pa
Answer:633.8 KJ
Explanation:
Given
mass of water
Initial temperature
Final temperature
Specific heat of water =4190 J/kg-k
heat of vaporization
Heat required for process=heat to raise water temperature from 20 to 100 +Heat to vapourize water completely

Answer:
d = 18 m
Explanation:
Given that,
The speed of a baseball, v = 36 m/s
We need to find the distance from the mound to home plate if the ball takes 0.5 seconds to leave the pitcher's hand and cross the plate.
Let the distance be d. We can find it using the formula,
Speed = distance/time
or
So, the required distance is equal to 18 m.
Answer:

Explanation:
Image 1- <u>wheels of train</u> showing both translatory motion as well as rotatory motion.
Image 2- <u>rotation of ball</u> shows both rotatory motion as well as translatory motion.
Image 3- <u>the earth rotates</u> about its axis, same time it revolves around the sun thus showing both rotatory motion and curvilinear motion in a fixed time. (perodic motion)
Image 4- while cutting wood, <u>the</u>
<u>carpenter's</u> <u>saw</u> has both
translatory motion and oscillatory
motion, as it moves down while
oscillating.
