Answer:
The value is
Explanation:
From the question we are told that
The number of students is
The metabolic rate for each student is
The time duration is
The molar specific heat of air is
The volume is
The pressure is
The initial temperature is
Generally the metabolic rate of the students is
=>
=>
The total heat generated by the students is
=>
=>
From the ideal gas law we can evaluate n (number of moles ) as
Here R is the gas constant with value
So
=>
Generally the heat generated is mathematically represented as
=>
=>
=>
=>
Waves transfer energy over distance without moving matter the entire distance. So your answer would be energy.
Answer:
the maximum force will be equal to 134.84 N
Explanation:
We have given mass m = 43 kg
Coefficient of static friction
Acceleration due to gravity
We have to find the maximum force which , when applied there is no movement of crates
This maximum force will be equal to frictional force
Frictional force is given by
So the maximum force will be equal to 134.84 N
Answer:
t = 6 [s]
Explanation:
In order to solve this problem we must first use this equation of kinematics.
where:
Vf = final velocity = 0 (the car comes to rest)
Vo = initial velocity = 72 [km/h]
a = acceleration [m/s²]
x = distance = 60 [m]
First we must convert the velocity from kilometers per hour to meters per second.
Now using this other equation of kinematics.
0 = 20-3.33*t
t = 6[s]
