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:
780 m to travel north
Explanation:
6 m over = 750
53 degree so it will take about 2 min to reach the destination
A flashlight is charged by shaking an internal magnet back and forth through coiled wires.
Explanation:
Charging a flashlight by shaking an internal magnet back and forth through coiled wires can cause electromagnetic induction to occur. The wire is in the vicinity of changing magnetic fields.
- Electromagnetic induction or induction is the production of electromotive force(EMF) by varying the magnetic field in an electrical conductor.
- The wire serves as the electrical conductor.
- As the magnetic flux on it changes, the electromotive force is then produced.

Answer: This is due to the Magnus Effect
Explanation: "Which is the force exerted on a rapidly spinning cylinder or sphere moving through air or another fluid in a direction at an angle to the axis of spin. This force is responsible for the swerving of balls when hit or thrown with spin."
Answer:
12N to the right.
Explanation:
There is a force of 12N upwards and a force of 12N downwards: these cancel out.
Assign a negative value to forces towards the left, and a positive value to the forces towards the right: -3N and +15N
Combine them: -3N+15N = 12N
The net force has a magnitude of 12N, and since our answer was positive, it acts towards the right.
