Answer:

203.1J

Explanation:

Given parameters:

Mass = 65kg

Speed = 2.5m/s

Unknown:

Kinetic energy of jogger = ?

Solution:

To solve this problem, we use the kinetic energy equation:

K.E = $\frac{1}{2}$ m v²

m is the mass

v is the velocity

Now insert the parameters and solve;

K.E = $\frac{1}{2}$ x 65 x 2.5² = 203.1J

what is the percent efficiency of a light bulb that emits 14 joules of light for every 60 joules of electric energy thst enters

jasenka [17]

If you're using the bulb as a source of light, then it's. 14/60 = 23.3% efficient.
If you're using it to heat a bird nest or a hamster cage, then it's. 46/60 = 76.7% efficient !
It just depends on your point of view, and what you consider 'useful' output.

How does distance from the equator affect the climate of an area?

AVprozaik [17]

Explanation :

There are different factors that affect the climate of an area.The distance from the equator is one of them.

Equator is closest to the sun. The rays from the sun strikes mostly near equator and gets spread over the larger area. Hence, equators are much hot as compared to that of poles.
