Which of the following can lower the activation energy of a system?

Physics

exis [7]3 years ago
8 0
Catalysts
a catalyst is something added to a reaction that speeds it up (or lowers the activation energy)

increasing the temp would speed up the whole reaction but not lower the activation energy
so B.

A projectile is fired directly upward from the ground with an initial velocity of 112 f/sec its distance s above the ground afte
Travka [436]

Answer:

3.48 seconds

Explanation:

At maximum height Vf=0 m/s

Vf= Vi - g*t

⇒g*t= Vi

⇒t= Vi/g

⇒t= 112/32.17 sec

⇒ t= 3.48 s

so the projectile will achieve its maximum height in 3.48 seconds.

a ball drops some distance and loses 30 j of gravitational potential energy. do not ignore air resistance. how much kinetic ener
aniked [119]

Thus, more than 30 J of potential energy can be loosed by the ball. Thus, the gravitational potential energy of the ball is more than 30 J.

If there is no air resistance, the ball's potential energy is entirely transformed into kinetic energy. When air resistance is taken into account, a portion of the potential energy is used to overcome it. Thus, AU > AKE. In the current scenario, a ball gains 30 J of kinetic energy while falling and is treated as encountering air resistance. The energy that an object retains due to its position in relation to other objects, internal stresses, electric charge, or other factors is known as potential energy in physics. The potential energy will be transformed into kinetic energy if the stones fall. High on the tree, branches have the potential to fall, which gives them energy. Chemical potential energy exists in the food we eat.

The handles of the tools like screwdrivers and pliers used by electricians for repair work usually have plastic or rubber covers
fenix001 [56]

Answer:

Rubber or plastic covers are bad conductors of electricity. So they do not allow the electric current to pass through it.

Explanation:

Rubber and plastic are bad conductors of electricity, therefore when handling a tool with a rubber handle, the electricity will not pass through it.
