1. A group of experienced climbers are going rock climbing. What simple machine should they bring to help with the climbing? Why? 2. The children at the local pool have noticed that the bottom of the pool is very slippery. You have been asked to come up with a plan for increasing the friction on the pool bottom. What would you suggest?

I will give you brainiest if you answer me please help me

Pickax and  rope and a hook the reason why the pickax to pick on the rocks and the hook to hook your self safely on the rocks and the rope to hold you on the hook

2, Dycem material because is the ideal non-slip material choice for improving grip, providing stability

Explanation:

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
