Answer:
W= F × d
W= 2kn × 3.6
W= 7.2 J
Work is measured in Joules!
Answer:
The chemical processes maintaining balance within the living organism
Explanation:
- Homeostasis is a state or mechanism of the internal physical and the chemical conditions that are maintained by the living system. It is a condition that states the optimal functioning of the organism and include variables like body temperature and fluid balances.
Answer:
Explanation:
A hand-pumped water gun is held level at a height of 0.75 m, this part miss of the question so now:
h=0.75 m
x=7.3 m
Gauge Pressure can be find
The frequency of the nth-harmonic of a standing wave is an integer multiple of the fundamental frequency of the string, according to:
(1)
where
is the fundamental frequency.
We know the frequency of the 4th overtone (44 kHz), which corresponds to the 5th harmonic (n=5). Therefore, we can find the fundamental frequency of the string by rearranging equation (1):
And by using the same formula we can find the following harmonics:
And since the audible range for human goes from 20 Hz to 20 kHz, we see that onlyt the first two harmonics (8.8 kHz and 17.6 kHz) will be audible to a human.
Answer:
Explanation:
Given
velocity of boat with respect to river
velocity of river is
River is 3.5 km wide
Suppose boat leaves at an angle of with vertical such that it reaches exactly opposite end of initial Point
Therefore
component will balance the river Flowso that sin component helps to cross the river
