Answer:
Because it comprises both physical and mental activities.
Explanation:
Orienteering is a sport that is known for its physical and mental activities. It is an ideal sport for the most promotion of physical activity and lifetime sports because it involves moving through the wild or difficult terrain. This takes energy to be competitive, and it also requires participants to take challenging decisions now and then.
People of different ages can participate and allows them to apply real-world decision-making skills to the competition. It also gives participants the chance to learn about themselves more and how to face different situations.
Answer:
The induced current is 
Explanation:
From the question we are told that
The number of turns is 
The cross-sectional area is 
The initial magnetic field is 
The magnetic field at time = 1.02 s is 
The resistance is 
The induced emf is mathematically represented as
The negative sign tells us that the induced emf is moving opposite to the change in magnetic flux
Here 
is the change in magnetic flux which is mathematically represented as
Where dB is the change in magnetic field which is mathematically represented as
substituting values
Thus
So
The induced current i mathematically represented as
substituting values
Copper is a better conductor.
Answer:
- A book lying on a table - Balanced force
- An airplane cruising in level flight - Balanced
- A rock falling from a cliff - Unbalanced force
- A bridge collapsing in an earthquake - Unbalanced force
- A man sitting on a park bench - Balanced force
- A space shuttle taking off - Unbalanced force
- A car maintaining a constant speed on a straight road - Balanced force
- An airplane landing - Unbalanced force
Explanation:
Usually, one or more forces act on a body at an instant of time. When these forces acting on a body and bring the body in the equilibrium position, the force is said to be balanced. The unbalanced force changes the equilibrium state of the body.
As in the case of an airplane cruising in a level flight, the weight of the plane will be equal to the lift force and the thrust is equal to the drag. So the plane is experiencing a balanced force.
