Answer: The equilibrium constant can help us understand whether the reaction tends to have a higher concentration of products or reactants at equilibrium. We can also use K c K_\text c KcK, start subscript, start text, c, end text, end subscript to determine if the reaction is already at equilibrium.
Explanation:
Answer:
The beat frequency is 6.378 Hz.
Explanation:
Given that,
Length of wire = 10000 m
Weight = 81.34 N
Distance = 0.660 m
Tension = 52 N
Frequency = 196 Hz
We need to calculate the mass of the wire
Using formula of weight


Put the value into the formula


The mass per unit length of the wire

Put the value into the formula


We need to calculate the frequency in the wire
Using formula of frequency

Put the value into the formula


We need to calculate the beat frequency
Using formula of beat frequency

Put the value into the formula


Hence, The beat frequency is 6.378 Hz.
Solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose
The kinetic energy of the object just after it starts its motion from the Earth surface is

where m is the object mass and

its initial speed.
When it reaches its maximum height, the object speed is zero and all its kinetic energy converted into gravitational potential energy, which is

where

and h is the maximum height reached by the object.
Since the energy of the object must be conserved, K=U, therefore we can write

and we can solve to find h, the maximum height:
Answer:
a) Suzie’s average acceleration = -6.46 m/s²
b) Force exerted to stop Suzie = 271.52 N
Explanation:
a) We have equation of motion, v = u + at
Final velocity, v = 0 m/s
Initial velocity, u = 32 mph = 14.22 m/s
Time, t =2.2 s
Substituting
0 = 14.22 + a x 2.2
a = -6.46 m/s²
Suzie’s average acceleration = -6.46 m/s²
b) Mass of Suzie = 42 kg
Force = Mass x Acceleration
F = Ma
F = 42 x -6.46 =-271.52 N
Force exerted to stop Suzie = 271.52 N
