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
=>
=>
=>
=>
Answer:
By dropping a pencil from a certain fixed height again and again it will make the target super messay with marks of dot everywhere on the target and some even out side the target.
Explanation:
We can first calculate the net force using the given information.
By Newton's second law, F(net) = ma:
F(net) = 25 * 4.3 = 107.5
We can now calculate the frictional force, f, which is working against the applied force, F(app) (this is why the net force is a bit lower):
f = F(net) - F(app) = 150 - 107.5 = 42.5 N
Now we can calculate the coefficient of friction, u, using the normal force, F(N):
f = uF(n) --> u = f/F(N)
u = 42.5/[25(9.8)]
u = 0.17
The gravitational force on two objects can be determined by the following equation:
Where G is the gravitational constant m1 is mass 1, m2 is the second mass nad r^2 is distance between these objects. Therefore, let m1 = mass of Sun 1.99x10^30 kg, m2= mass of Jupiter 1.90x10^27 kg, r is the average distance between the Sun and Jupiter 7.78x10^11 m. By plugging these values in we have:
F=4.17x10^23 N
