Mandarinka [93]

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.

At what distance of separation, or, must two 5.87*10^-8 coulomb charges be positioned in order for the repulsive force between t
kupik [55]

Explanation:

r^2= 9×10^9 × 5.87×5.87×10^-16 / 64.9

=47.7× 10^-8

so taking sq. root

r = 6.9 ×10^-4 m

or

r= 6.9×10^ -2 cm

this gives the required seperation

Select the correct answer.
Triss [41]

Answer:

Jim's kinetic energy is 54.67 J.

Explanation:

Given that,

Mass, m = 15 kg

Velocity, V = 2.7 m/s

We need to find the Jim's kinetic energy. We know that when the object is in motion, it has kinetic energy. This energy is given by :

E=\dfrac{1}{2}mv^2

E=\dfrac{1}{2}\times 15\ kg\times (2.7\ m/s)^2

E = 54.67 J

So, Jim's kinetic energy is 54.67 J. Hence, this is the required solution.
